Kadeploy: use of UUID partition identifiers and faster deployments
Up to now, kadeploy was identifying disk partitions with their block device names (e.g. /dev/sda3) when deploying a system. This no longer works reliably because of disk inversion issues with recent kernels. As a result, we have changed kadeploy to use filesystem UUIDs instead.
This change affects the root partition passed to the kernel command line as well as the generated /etc/fstab file on the system.
If you want to keep identifying the partitions using block device names, you can use the "--bootloader no-uuid" and the "--fstab no-uuid" options of g5k-postinstall, in the postinstalls/script of the description of your environment. Please refer to the "Customizing the postinstalls" section of the "Advanced Kadeploy" page: Advanced_Kadeploy#Using_g5k-postinstall
As an additional change, Kadeploy now tries to use kexec more often, which should make the first deployment of a job noticeably faster.

New monitoring service with Kwollect is now stable
The new Grid'5000 monitoring service based on Kwollect is now stable. Kwollect will now serve requests adressed to Grid'5000 "Metrology API", i.e., from this URL:
The former API based on Ganglia is no longer available, and Ganglia will be removed from Grid'5000 environments starting from the next Debian version (debian11).
Main features of Kwollect are:
- Focus on "environmental" monitoring, i.e. metrics not available from inside the nodes: electrical consumption, temperature, metrics from network equipments or nodes' BMC… but Kwollect also monitors node's metrics from Prometheus exporters
- Support for Grid'5000 wattmeters at high frequency
- On-demand activation of optional metrics
- Custom metrics can be pushed by users
- Grafana-based vizualisation
Its usage of this new service is described at: Monitoring_Using_Kwollect
Here are the main other changes since the last annoucement on December:
- Monitoring related entries in Reference API have been cleaned (nodes' "sensors" and "wattmetre" keys removed, "pdu" moved at top level), OAR property wattmeter=SHARED and wattmeter=MULTIPLE removed
- Visualization now uses Grafana
- Metrics naming and polling period have been updated
- Grid'5000 documentation has been updated
- Bugs and performance fixes

Upgrade of the graffiti-13 node in Nancy
We are happy to announce that the graffiti-13 node on the Nancy site in production queue has been upgraded: its 4 GeForce RTX 2080 Ti 11GB have been replaced by 4 RTX 6000 24GB GDDR6.
Reservation example : oarsub -q production -p "host='graffiti-13.nancy.grid5000.fr'" -I

Yeti nodes now equipped with 2 NVMe of 1.6 TB and made exotic resources
The yeti nodes of the Grenoble site now have 2 NVMe drives of 1.6TB again (back to their original configuration of 2018) and the troll nodes have new NVMe (1.6TB also, but newer model).
The 4 new NVMe were financed by the Software Heritage project. Many Thanks.
Since the 4 yeti nodes are the only quadri-cpu resources of Grid'5000 and with 2 NVMe, they are now defined as exotic resources, and must be reserved with `-t exotic` in the oarsub arguments.

Docker cache available inside Grid5000
With the growing use of Docker, you might have experienced some rate limiting when pulling images due to the Docker Hub recent policy change.
As a result, we now provide a Docker cache accessible from inside Grid'5000 at the following address http://docker-cache.grid5000.fr
For configuration instructions and more information, see: Using docker-cache.grid5000.fr

Grid'5000 environments now use zstd compression
We are moving the default image archive format used for Grid'5000 environments from tar.gz to tar.zst. Switching to zstd allows for significantly faster decompression speed.
This change is transparent for most usages. Kadeploy will use zstd transparently for environments using it (e.g. new environments), the main impact is that deployment will be faster. If kameleon is used to generate an environment (thus creating an environment description file and an image archive), it will now automatically use zstd by default.
However if you manually modify the description of an environment and/or regenerate an image archive with tgz-g5k (using the -z switch for zstd), you may have to make sure that both use the same compression.
This change is part of a larger effort to improve the performance of kadeploy.

Guix package manager available on Grid'5000
We now offer the possibility to use Guix on Grid'5000 as a package manager to install new software or build container images without the need to be root.
It is available on frontends and nodes (on standard or deployed *-nfs or *-big environments with your user).
This work has been done in collaboration with the Guix HPC team.

New cluster "grouille" available in Nancy
We have the pleasure to announce that a new cluster named "grouille" is available in Nancy in the default queue. It features 2 Dell R7525 nodes with two AMD EPYC 7452 32-Core CPUs, two NVidia A100-PCIE-40GB GPUs, 128GB of DDR-4 RAM, one 1.8TB SAS SSD and one 900GB SATA SSD (reservable). The reservation of the Grouille nodes requires using the "exotic" OAR job type.
This cluster has been funded by CPER Cyber Entreprises.

New Jupyter Notebooks interface
We are pleased to announce that Grid'5000 now offers a web interface to run and edit notebooks on the testbed. Available at https://intranet.grid5000.fr/notebooks/ , this interface allows users to start notebook applications on site's frontends or in OAR jobs.
Computational notebooks combine in a single file text, code cells, and the recorded outputs of the execution of the code. They can be used to track the evolution of an experiment during the exploratory phase, by recording one thought process in the text cells and the experiments in the code cells. Or to create self-generating experiment reports where the general explanation is in the text and the precise data points are generated by the code in the output cells.
More info is available at Notebooks .

Change in the Omnipath network of Grenoble's site: all nodes now connected to a single switch
The Intel Omnipath network of the Grenoble site was changed recently due to technical constraints : It is now composed of only 1 Omnipath switch with all nodes connected to it (32 dahu + 4 yeti + 4 troll), while in the past the network was shared with the compute nodes of the HPC center of Université Grenoble Alpes, with the yeti and troll nodes connected to a different switch than the dahu nodes.
Please take that change into consideration in your experimentation.

IBM POWER8 cluster "drac" with P100 GPUs fully available in Grenoble
After a few months of testing, we are happy to announce that the new cluster "drac" is now available in the default queue in Grenoble.
The cluster has 12 "Minsky" nodes from IBM, more precisely "Power Systems S822LC for HPC". Each node has 2x10 POWER8 CPU cores, 4 Tesla P100 GPU, and 128 GB of RAM. The GPUs are interconnected pair-wise with a NVLINK fabric that is also connected to the CPUs (unlike the DGX-1 gemini nodes for instance). The nodes are interconnected with a high-speed Infiniband network with 2x100 Gbit/s on each node.
Be aware that this cluster is using an exotic architecture, and as such it may be more difficult than usual to install software. In particular, if you need to install to deep learning frameworks on these nodes, make sure to read our documentation:
In addition, when reserving the nodes, you need to explicitly ask for an "exotic" job type. For instance, to obtain a single node:
grenoble> oarsub -I -t exotic -p "cluster='drac'"
Acknowledgment: This cluster was donated by [GENCI https://www.genci.fr/en] (it was formerly known as the Ouessant platform of Genci's Cellule de Veille Technologique), many thanks to them.
More information on the hardware is available at Grenoble:Hardware#drac

Troll and Gemini clusters are now exotic resources (change in the way to reserve them)
Clusters Troll on Grenoble and Gemini on Lyon are now considered exotic resources, and must be reserved using the exotic OAR job type. When a cluster on Grid'5000 has a hardware specificity that makes it too different from a "standard" configuration, it is reservable only using the exotic OAR job type. There are 2 reasons for this:
- It ensures that your experiment won't run on potentially incompatible hardware, unless you explicitly allow it. (for example, you don't want to get a aarch64 cluster if your experiment is built for x86)
- By not allocating these resources to jobs by default, it makes them more easily available for users who are looking specifically for this kind of hardware.
There is an example of usage of the exotic job type in the getting started : https://www.grid5000.fr/w/Getting_Started#Selecting_specific_resources
You can see if a cluster is exotic in the reference API or on the Hardware page of the wiki : https://www.grid5000.fr/w/Hardware#Clusters There are currently 4 clusters which needs the exotic job type to be reserved :
- pyxis because it has a non-x86 CPU architecture (aarch64)
- drac because it has a non-x86 CPU architecture (ppc64)
- troll because it has PMEM ( https://www.grid5000.fr/w/PMEM )
- gemini because it has 8 V100 GPU per node, and only 2 nodes

New Grid'5000 API's documentation and specification
Grid'5000 API's documentation has been updated. Before this update, the documentation contained both the specification and tutorials of the API (with some parts also present in the wiki).
To be more consistent, https://api.grid5000.fr/doc/ provides now only the specification (HTTP paths, parameters, payload, …). All tutorials were moved (along with being updated) to the Grid'5000's wiki.
Please note that the specification may contain errors. Please report any of such errors to Support Staff.

Important changes in the privileges levels of users
Each Grid'5000 user is a member of at least one granting access group, which depends on their situation (location, laboratory, ...). Each group is given a privilege level (bronze, silver, gold), depending on how the related organization is involved in Grid'5000's development and support.
Until now, however, these levels had no impact on how Grid'5000 could be used.
Starting from December 10th, 2020, each user will be granted different usages on the testbed depending on their privileges level. In particular:
- While every level continues to give access to the Grid'5000 default queue (most of Grid'5000 resources) ;
- Access to the production and besteffort queues will only be granted to silver and gold levels.
The complete description of each level of privileges is available here.
The privilege level of the groups a user is a member of is shown in the "group" tab of the management interface.
Note that if a user is a member of several groups, one is set as default and is implicitly used when submitting jobs. But the "--project" OAR option can also set explicitly which group the job should use. For instance:
oarsub-I -q production --project=
Do not hesitate to contact the Support Staff for any questions related to the privilege levels.

oarsub -t night ... to submit a job to run during the coming (or current) night (or week-end on Friday). As such:
- It will be forced to run after 19:00, and before 9:00 for week nights (Monday to Thursday nights), or before 9:00 on the next Monday for a job which runs during a week-end.
- If a job could not be scheduled during the current night because not enough resources are available, it will be kept in the queue for an automatic retry the next night (hour constraints will be changed to the next night slot), that for 7 days.
- If the walltime of the job is more than 14h, the job will obviously not run before a weekend.
- the maximum walltime for a night is 14h, but due to some overhead in the system (resources state changes, reboots...), it is strongly advised to limit walltime to at most 13h30. Furthermore, a shorter walltime (max a few hours)? will result in more chances to get a job scheduled in case many jobs are already in queue.
- jobs with a walltime greater than 14h will be required to run during the week-ends. But even if submitted at the beginning of the week, they will not be scheduled before the Friday morning. Thus, any advance reservation done before Friday will take precedence. Also, given that the rescheduling happens on a daily basis for the next night, advance reservations take precedence if they are submitted before the daily rescheduling. In practice, this mechanism thus provides a low priority way to submit batch jobs during nights and week-ends.
- a waiting job will be kept max 7 days in queue before deletion if it could not run because of lack of resources.

New ARM cluster "Pyxis" available on Lyon (testing queue)
We have the pleasure to announce that a new cluster named "pyxis" is available in the testing queue in Lyon. It is the first cluster with ARM CPU (ThunderX2 9980) in Grid'5000 ! This cluster is composed of 4 nodes, each of them with 2 ThunderX2 9980 CPU (32 cores/CPU, 4 threads/cores), 256 GB RAM, 2 x 250 GB HDD, 10 Gbps Ethernet. Each node's power consumption is monitored with the wattmetre of Lyon (although it is currently broken¹). It is planned to add Infiniband network to Pyxis.
Pyxis nodes can be reserved in the testing queue with the exotic job type (add "-q testing -t exotic -p cluster='pyxis'" to your OAR submission) and arm64 environments are available to be deployed on this cluster. Beware that as it is a different CPU architecture, compiled programs targeting x86 (such as those provided by module) won't execute. Any feedback is welcome.
This cluster has been funded by the CPER LECO++ Project (FEDER, Région Auvergne-Rhone-Alpes, DRRT, Inria).

Important change in the User Management System - Groups which Grant Access to the testbed
An important update to the Grid'5000 User Management System just happened. This update brings a new concept: users now get granted access to the testbed through a group membership.
These Groups which Grant Access (GGAs) allow a dispatch of the management and reporting tasks for the usage of the platform to closer managers than the Grid’5000 site managers.
Every user has to be a member of a GGA to be allowed access to the platform. The memberships are currently being worked by the staff, the site managers and new GGA managers.
You may receive emails about moves regarding your account: Don't worry. The transition to GGA should not impact your use of the platform and experimentations.
As a reminder, if you encounter problems or have questions, please report them either on the users mailing list or to the support staff, as described in the Support page. More information about this change is available in the User Management Service documentation page.

Using GNU Parallel in Grid'5000
The GNU Parallel tool, which is very relevant to complement OAR for many-tasks workloads following for instance the SPMD / embarrassingly parallel scheme, now benefits from a documentation page for its usage in Grid'5000.
GNU Parallel can be used within a OAR job, as the launcher for the many tasks. Thanks to oarsh, it can also dispatch many single GPU tasks on many GPUs.
See the the documentation page: GNU Parallel.

Major update of BIOS and other firmware and future strategy
In the recent months, we have performed a campaign of firmware updates (BIOS, Network interface Cards, RAID adapters…) of the nodes of most Grid'5000 clusters.
Those updates improved the overall reliability of our deployment process, but they also included mitigations for security issues such as Spectre/Meltdown.
It was also an opportunity to align clusters with similar hardware on the same firmware versions.
Unfortunately, we understand that those changes may have an impact on your experiments (particularly in terms of performance). This is a difficult issue where there is no good solution, as it is often hard or impossible to downgrade BIOS versions.
However, those firmware versions are included in the reference API. We recommend that you use this information to track down changes that could affect your experiment.
For instance, in https://api.grid5000.fr/stable/sites/nancy/clusters/gros/nodes/gros-1.json?pretty=1 , see bios.version and firmware_version. You can also browse previous versions using the API ¹, or using the Github commit history ²
We will continue to update such firmware in the future, about twice a year, keeping similar hardware in sync, and documenting the versions in the reference API.

New cluster available in Nancy: gros (124 nodes with reservable disks)
We have the pleasure to announce that the Gros cluster in Nancy (default queue) is now available:
It features 124 Dell R640 servers nodes with one Intel Gold 5220 (18 cores / 36 threads), 96 GB DDR4, 1x480 GB SSD + 1x960 GB reservable SSD  and 2x25Gbps Ethernet interfaces.
However, the installation of this cluster is not yet fully completed:
- Two nodes (gros-3 and gros-4) are in an artificial Dead state due to a kavlan issue we still have to fix with the new model of the network switches of Gros network.
- This cluster will be equipped with a high precision monitoring system for electrical power consumption (Multilab-R, from Omegawatt ) that is already used in Grid'5000 at Lyon  or Grenoble . It will be available for general use by the beginning of December.
- At the present time, the uplink between the Gros cluster and the Grid5000 network operates at 10Gbs. It will improved up to 2x40Gb/s in the next month.
This cluster has been funded by the CPER Cyber Entreprises project (Contrat de plan État / Région Lorraine 2015-2020).
Again, many thanks go to the former SIC and SG services at LORIA / Inria Nancy Grand Est for their help and support during this operation.
About the name: Gros is a french adjective which usually means large, big or fat, but when used as a noun in Lorraine (which is the region Nancy belongs to), it means something else. It is used here generally to talk about people one cares (friends, children, companions). Some examples:
- Comment que c'est gros ? (how do you do buddy ?). This is the most famous one, and we are pleased to shout it out loud when we enter into gros's server room. It seems to be spreading outside Lorraine as well.
- Les gros sont à l'école (children are at school)
- Wha gros c'est schteuff ! (Listen my friend, it's amazing !)

A new version of tgz-g5k has been released
We have released a new version of tgz-g5k. Tgz-g5k is a a tool that allow you to extract a Grid'5000 environment tarball from a running node. The tarball can therefore be used by kadeploy to re-deploy the image on different nodes/reservations (see Advanced Kadeploy for more details)
The new version has two major improvements:
- tgz-g5k is now compatible with Ubuntu and Centos
- tgz-g5k is directly usable on frontends (you do not need to use it through ssh anymore).
To use tgz-g5k from a frontend, you can execute the following command:
frontend$ tgz-g5k -m MY_NODE -f ~/MY_TARBALL.tgz
In case of specific or non-deployed environments: - tgz-g5k can use a specific user id to access nodes, by using the parameter -u (by default tgz-g5k accesses nodes as root) - tgz-g5k can access node with oarsh/oarcp instead of ssh/scp, by using the parameter -o (by default tgz-g5k uses ssh/scp)
Note that tg5-g5k is still compatible with the previous command line. For the record, you had to use previously the following command:
frontend$ ssh root@MY_NODE tgz-g5k > ~/MY_TARBALL.tgz

Enabling GPU level resource reservation in OAR
We have now put in service the GPU level resource reservation in OAR in Grid'5000. OAR now allows one to reserve one (or some) of the GPUs of a server hosting many GPUs, letting the other GPUs of the server available for other jobs.
Only the reserved GPUs will be available for computing in the job, as reported by the nvidia-smi command for instance.
- To reserve one GPU in a site, one can now run: $ oarsub -l gpu=1 ...
- To reserve 2 GPUs on a host which possibly has more than 2 GPUs, one can run: $ oarsub -l host=1/gpu=2 ...
- To reserve whole nodes (servers) with all GPUs, one can still run: $ oarsub -l host=3 -p "gpu_count > 0"
- To reserve specific GPU models, one can use the "gpu_model" property in a filter: $ oarsub -l gpu=1 -p "gpu_model = 'Tesla V100'"
- One can also filter on the cluster name after looking at the hardware pages for the description of the clusters: $ oarsub -l gpu=1 -p "cluster = 'chifflet'"
Finally, please notice that the drawgantts offer options to display GPUs.

OAR properties upgrade for jobs using GPUs
In order to allow GPU level resource reservations in OAR, we have to adapt some OAR properties.
Currently, there are two GPU-related properties that one can use in OAR: gpu and gpu_count (see: https://www.grid5000.fr/w/OAR_Properties#gpu ).
They can for instance allow one to reserve 3 hosts equipped with 2 GPUs GTX 1080 Ti: $ oarsub -p "gpu='GTX 1080 Ti' and gpu_count='2'" -l host=3 ...
The first required change is to rename the 'gpu' property to 'gpu_model'. The new oarsub command will hence become: $ oarsub -p "gpu_model='GTX 1080 Ti' and gpu_count='2'" -l host=3 ...
(the gpu property will later be repurposed to give the identifier of the GPU resource instead of the model)
Please make sure to update your scripts according to this change.
A maintenance will be operated on 2019-06-13 between 10:00 and 12:00 where all Grid'5000 will be unavailable for reservation, in order to achieve this change.
In second stage, in a future maintainance, we will add new OAR properties, allowing GPU level resource reservations.

New group storage service in beta testing, to replace storage5k
In order provide large, persistent and shareable storage among a group of user, we are introducing a new storage service. This service is now available for beta testing at Lille: if you need to store large amounts of data in Grid'5000, we recommend that you try it!
See https://www.grid5000.fr/w/Group_Storage for details.
The service will be extended to some other sites after the beta testing phase.
This service aims at replacing storage5k, and existing storage5k services will be shutdown. On Nancy and Luxembourg, the storage5k service will be retired on 2019-03-19, to free space in the server room for new machines. Other storage5k servers (on other sites) will be shutdown after the end of the beta phase of the new service.
If you are currently using Storage5k, your best options are:
- move data to your home directory (after requesting a disk quota extension if needed)
- move data to OSIRIM
- move data to the group storage service in Lille
See https://www.grid5000.fr/w/Storage for an overview of our storage options. (Note that we currently have two open issues with quota extensions and OSIRIM. If you submit a quota extension but do not receive a reply, or if you cannot access OSIRIM, please contact firstname.lastname@example.org)

After some investigations, we made these actions to fix the problems:
- Network monitoring has been disabled in Kwapi (servers were overloaded)
- Code has been optimized and many bugs have been fixed.
- Reliability problems with measurements made on some Power Delivery Units have been identified and Kwapi has been disabled on clusters where these problems are too important.
- The time resolution of some PDUs has been updated in the reference API
Some details about PDU measurements issues can be found here: https://www.grid5000.fr/mediawiki/index.php/Power_Monitoring_Devices#measurement_artifacts_and_pitfalls
The current status of Kwapi energy monitoring can be checked here: https://intranet.grid5000.fr/jenkins-status/?job=test_kwapi For every clusters marked "green", Kwapi can be considered to be functional.
Cluster where dedicated monitoring devices are available (Lyon and Grenoble) are still fully fonctional.

New clusters available in Grenoble
We have the pleasure to announce that the 2 new clusters in Grenoble are now fully operational:
- dahu: 32x Dell PE C6420, 2 x Intel Xeon Gold 6130 (Skylake, 2.10GHz, 16 cores), 192 GiB RAM, 240+480 GB SSD + 4.0 TB HDD, 10 Gbps Ethernet + 100 Gbps Omni-Path
- yeti: 4x Dell PE R940, 4 x Intel Xeon Gold 6130 (Skylake, 2.10GHz, 16 cores), 768 GiB RAM, 480 GB SSD + 2x 1.6 TB NVME SSD + 3x 2.0 TB HDD, 10 Gbps Ethernet + 100 Gbps Omni-Path
These nodes share a Omnipath network with 40 additionnal "dahu"s, operated by GRICAD (Mésocentre HPC of Univ. Grenoble-Alpes) and are equipped with high frequency power monitoring devices (same wattmeters as in Lyon). This equippement was mainly funded by the LECO CPER (FEDER, Région Auvergne-Rhone-Alpes, DRRT, Inria), and the COMUE Univ. Grenoble-Alpes.

New environnements available for testing: Centos 7, Ubuntu 18.04, Debian testing
Three new environments are now available, and registered on all sites with Kadeploy: Centos 7 (centos7-x64-min), Ubuntu 18.04 (ubuntu1804-x64-min), Debian testing (debiantesting-x64-min).
They are in a beta state: at this point, we welcome feedback from users about those environments (issues, missing features, etc.). We also welcome feedback on other environments that would be useful for your experiments, and that are currently missing from the set of environments provided on Grid'5000.
Those environments are built with Kameleon <http://kameleon.imag.fr/>. Recipes are available in the 'newrecipes' branch of the environments-recipes git repository: https://github.com/grid5000/environments-recipes/tree/newrecipes
Our testing indicates that those environments work fine on all clusters, except in those cases:
- Debian testing on granduc (luxembourg) and sagittaire (lyon): deployment fails due to lack of entropy after boot (related to the fix for CVE-2018-1108)
- Debian testing on chifflot (lille): deployment fails because the predictable naming of network interfaces changed

New clusters available in Lille
We have the pleasure to announce that 2 new clusters are available in Lille:
- chifflot : 8 Dell PE R740 nodes with 2 x Intel Xeon Gold 6126 12C/24T, 192GB DDR4, 2 x 447 GB SSD + 4 x 3.639 TB SAS including
- chifflot-[1-6] nodes with 2 Nvidia P100
- chifflot-[7-8] nodes with 2 Nvidia V100
- chiclet : 8 Dell PE R7425 nodes with 2 x AMD EPYC 7301 16C/32T, 128GB DDR4
These nodes are connected with 25Gb Ethernet to a Cisco Nexus9000 switch (reference: 93180YC-EX)
The extension of the hardware equipment at the Lille's site of Grid'5000 is part of the Data (Advanced data science and technologies) CPER project carried by Inria, with the support of the regional council of Hauts-de-France, FEDER and the State.

Change in user's home access
During this week, we will change the access policy of home directories in order to improve the security and the privacy of data stored in your home directory.
This change should be transparent to most users, as:
- You will still have access to your local user home from reserved nodes when using the standard environment or when deploying custom environments such as 'nfs' or 'big'.
- You can still access every user's home from frontends (provided the access permissions allow it).
However, in other situations (give access to your home to other users, mount home directory from another site or inside a virtual machine or from a VLAN, ...), you will need to explicitely allow access using the new Storage Manager API. See https://www.grid5000.fr/w/Storage_Manager
Note that this change requires a switch to autofs to mount /home in user environments. This should be transparent in most cases because g5k-postinstall (used by all reference environments) has been modified. However, if you use an old environment, it might require a change either to switch to g5k-postinstall, or to switch to autofs. Contact us if needed.

New production cluster in Nancy: grvingt
We are happy to announce that a new cluster with 64 compute nodes and 2048 cores is ready in the *production queue* in Nancy !
This is the first Grid'5000 cluster based on the latest generation of Intel CPUs (Skylake).
Each node has:
- two Intel Xeon Gold 6130 (Skylake, 2.10GHz, 2 CPUs/node, 16 cores/CPU)
- 192GB of RAM
- 1TB HDD
- one 10Gbps Ethernet interface
All nodes are also connected with an Intel Omni-Path 100Gbps network (non-blocking).
This new cluster, named "grvingt", is funded by CPER CyberEntreprises (FEDER, Région Grand Est, DRRT, INRIA, CNRS).
As a reminder the specific rules for the "production" queue are listed on https://www.grid5000.fr/w/Grid5000:UsagePolicy#Rules_for_the_production_queue
 Important note regarding pronunciation: despite the Corsican origin, you should pronounce the trailing T as this is how "vingt" is pronounced in Lorraine.

Debian 9 environments now use predictable network interfaces names
All our Debian 9 environments have now been modified to use predictable network interfaces names (eno1, ens1, enp2s0, etc. instead of the traditional eth0, eth1, etc.), which is now the default on Debian and most other distributions. You can read more about this standard on https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames .
Because Grid'5000 nodes use different hardware in each cluster, the default network interface name varies, depending on whether it is included on the motherboard or an external NIC plugged in a PCI Express slot.
The mapping between old and new names is available on each site's Hardware page, such as https://www.grid5000.fr/mediawiki/index.php/Nancy:Hardware .
Some useful commands:
- ip link show up : show network interfaces that are up
- ip -o link show up : show network interfaces that are up (one-line format)
- ip addr show up : show network addresses for interfaces that are up
- ip -4 addr show up : show network addresses for interfaces that are up (IPv4 only)
- ip -o -4 addr show up : show network addresses for interfaces that are up (IPv4 only, one-line format)
If you want to stick with the old behaviour, you can either:
- use older versions of the environments, available in /grid5000
- change the environment description (kadeploy .dsc file) and add "--net traditional-names" to the call to g5k-postinstall.
Typically, that would mean:
- Get the current environment description:
kaenv3 -p debian9-x64-min > myenv.dsc
- edit myenv.dsc, find the "script:" line, and add "--net traditional-names" to make it, for example:
script: g5k-postinstall --net debian --net traditional-names
- deploy using: kadeploy3 -a myenv.dsc -m mynode

Spring cleanup: removal of wheezy environments, and of HTTP proxies
We recently removed some old cruft.
First, the Debian 7 "wheezy" environments were removed from the Kadeploy database. They remain available on each frontend under /grid5000 for the time being. As a reminder, older environments are archived and still available : see /grid5000/ README.unmaintained-envs for details.
Second, we finally removed the HTTP proxies, that were used in the past to access the outside world from Grid'5000. This removal might cause problems if you use old environments that still rely on HTTP proxies. However, you can simply drop their use.
An upcoming change is the switch to predictable names for network interfaces in our Debian9 environments. More information on this will follow when it is deployed.

Looking back at the first Grid'5000-FIT school
The first Grid’5000-FIT school was held in Sophia Antipolis, France from April 3rd to April 6th, 2018.
During three full days, more than 90 researchers (among them 30 PhD and 8 master students) studied jointly the two experimental research infrastructures Grid’5000 and FIT.
In addition to high profile invited speakers and more focused presentations for testbeds users, the program included 30 hours of parallel hands-on sessions. As such, introductory and advanced lab sessions on Grid’5000, FIT IoT-Lab, FIT CorteXlab and FIT R2lab were organized by the testbeds developers, each attracting dozens of attendants. See http://www.silecs.net/1st-grid5000-fit-school/program/ for more details on the presentations and on the hands-on sessions.
The last day, a hackathon involving several participating ad-hoc teams was organized. The hackathon aimed to use heterogeneous testbed resources as a substrate for building an IoT application from collection of IoT-originating data to cloud-based dashboard.
This event is the first public milestone towards the SILECS project that aims at bringing together both infrastructures. See http://www.silecs.net/ for more details on SILECS.

Debian 9 environments updated, with Meltdown patches
As you probably know, a serie of vulnerabilities has recently been discovered in x86 processors[1,2]. This update of our environments is the first to include a mitigation patch for it. However, this patch causes an important performance penalty for syscall-intensive workloads (e.g. performing a lot of I/O). We decided to follow Linux kernel defaults, and activate this patch by default, as it seems that we will all have to live with it for the foreseable future.
However, if you want to avoid this performance penalty for your experiments, you have two options: 1) Use version 2017122808 of our environments (which does not include the updated kernel) 2) Disable Kernel Page Table Isolation, by adding pti=off to the kernel command line. To do that, after deployment, edit /etc/default/grub, add pti=off to GRUB_CMDLINE_LINUX_DEFAULT, run update-grub, reboot
Many evaluations of the performance penalty are available online[3,4].
Here is an instance, measured on the grele cluster, using 'time dd if=/dev/zero of=/dev/zero bs=1 count=20000000', which is very close to a worst-case workload. The results are for one run, but they are fairly stable over time.

1st Grid'5000-FIT school: save the date, call for presentations and practical sessions
It is our pleasure to announce the first Grid’5000-FIT school, that will be held in Sophia Antipolis, France from April 3rd to April 6th, 2018. This event is a first public milestone in the SILECS project, that aims at bringing together Grid'5000 and FIT infrastructures.
The program is being polished and will be available soon on http://www.silecs.net/1st-grid5000-fit-school/. The week of work will give priority to practical sessions where you will use the FIT and Grid’5000 platforms and learn how to conduct scientific and rigorous experiments. Moreover, to foster collaboration, we will arrange a special session where you can present your own work (see “call for presentations” below) or propose your own practical session (see “Call for practical session” below).
We would like to stress in this announcement that we hope users will consider presenting their great work during the school, including already published results. The focus of user presentations during the school is not so much on new results but on showcasing great uses of Grid’5000 and/or FIT platforms, singly or together, with a focus on how the results have been derived from the platforms usage.
Registration will be free but mandatory due to the limited number of seats.
Stay tuned for extra details on http://www.silecs.net/1st-grid5000-fit-school/.

Standard environments upgraded to Debian 9 "stretch"
All Grid'5000 nodes now use Debian 9 "stretch" as standard environment (this is the environment available by default when not deploying).
Known remaining problems at this time are: - Lyon, orion cluster: GPUs are no longer supported by CUDA 9 wich is the version now included in debian 9 environments. - Infiniband support: while we think we have resolved everything, we are not 100% sure at this point (it needs further testing). - Virtual machines on the standard environment don't work anymore (but work if you deploy, of course)
Your own scripts or applications might require changes or recompilation to work on Debian 9. If we want to stick with Debian 8 for the time being, you can still manually deploy the jessie-x64-std environment.

Debian 9 "stretch" environments now available for deployments
Kadeploy images are now available for Debian 9.
We used this opportunity to change the naming scheme, so they are named debian9-x64-min, debian9-x64-base, debian9-x64-nfs, debian9-x64-big.
Known regressions and problems are :
- The Xen environment is not available yet
- Network interfaces use the traditional naming scheme (eth0, eth1, ...) not yet the new predictable scheme
- Intel Xeon Phi (for the graphite cluster in Nancy) is not supported yet
- Infiniband network support is currently not tested
We are planning to switch the "std" environment (the one available when not deploying) in the coming weeks. You can beta-test the environment that we plan to switch to (debian9-x64-std).
Please report problems you encounter with the above environments to email@example.com.

Grid'5000 Usage Policy updated
The Grid'5000 Usage Policy has been updated.
In a nutshell, all usage that was previously allowed is still allowed after this update.
However, there are several changes to help increase usage of resources that are immediately available.
- Jobs of duration shorter or equal to one hour, whose submission is done less than 10 minutes before the job starts, are excluded from daily quotas.
- This means that one can always reserve resources for up to one hour when they are immediately available.
- Similarly, job extensions requested less than 10 minutes before the end of the job, and for a duration of one hour or less, are also excluded from daily quotas. Those extensions can be renewed several times (always during the last 10 minutes of the job).
- This means that, when resources are still available, one can always extend jobs for up to one hour.
- Crossing the 19:00 boundary is allowed for jobs submitted at or after 17:00 the same day. The portion of those jobs from 17:00 to 19:00 is excluded from daily quotas.
- This means that if at 17:00 or later on a given day, resources are not reserved for the following night, then it is possible to reserve them and start the night job earlier.
- Crossing the 9:00 boundary is allowed for jobs submitted on the same day. But the portion of those jobs after 9:00 is still included in the daily quota.
- This means that when resources are free in the morning, people are free to start working earlier.
Note that with those changes, it might become harder to get resources if you do not plan at least one hour ahead.
Another change is that the usage policy now includes rules for disk reservations.
Comments about those new rules are welcomed on the users mailing list.

Such a change is granted with respect to the resources occupation by other jobs and the resulting job characteristics still have to comply with the Grid'5000 Usage Policy¹. You may use the oarwalltime command or use the Grid'5000 API to request or query the status of such a change for a job. See the Grid'5000 tutorials and API documentation for more information.
¹ Rules from the Usage Policy still apply on the modified job. We are however considering changing the Usage Policy to take the new feature into account, and would welcome ideas toward doing that. Please feel free to make suggestions on firstname.lastname@example.org.
