Update about Kwapi status
For some time now there were several issues with kwapi monitoring of energy consumption and network traffic on Grid5000.
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.

100 Gbps Omni-Path network now available
Omni-Path networking is now available on Nancy's grele and grimani clusters.
On the software side, support is provided in Grid'5000 environments using packages from the Scibian distribution, a Debian-based distribution for high-performance computing started by EDF.
OpenMPI automatically detects and uses Omni-Path when available. To learn more about how to use it, refer to the Run MPI on Grid'5000 tutorial.
More new clusters with Omni-Path networks are in the final stages of installation. Stay tuned for updates!

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 firstname.lastname@example.org.

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.

Changing job walltime
The latest OAR version installed in Grid'5000 now provides the functionality to request a change to the walltime of a running job (duration of the resource reservation). 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 email@example.com.
