How to access and work on Talc
From LORIA network
| mypc:
| ssh -p 2222 jdoe@access.nancy.grid5000.fr |
From external
Use the national access.
|
| mypc:
| ssh jdoe@access.grid5000.fr |
Then, connect to the frontend for Talc.
|
| access:
| ssh talc.nancy |
These two steps can be automatized using ~/.ssh/config :
Host access
HostName access.grid5000.fr
User jdoe
Port 22
IdentityFile /home/doe/.ssh/id_dsa
ForwardAgent no
Host *.user
User jdoe
ProxyCommand ssh access "nc -q 0 `basename %h .user` %p"
ForwardAgent no
|
| mypc:
| ssh talc.nancy.user |
Disks utilization
You can use tmp directory during your reservation. Prefer local disk to nfs home during your experiments for better performance. Once your reservation is terminated, tmp will be formatted.
| Note |
|---|---|
- access.nancy.grid5000.fr is not the frontend for Talc. It's just the access machine used for the ssh redirection. | |
How to access data in Inria/Loria environment
loria1.loria.fr is an access machine hosted on Loria side. That machine can be used to access all services on Inria/Loria environment.
You need to use Ssh ProxyCommand for that purpose.
Adapt following lines for your ~/.ssh/config
Host accessloria
HostName loria1.loria.fr
User jdoe
Port 22
IdentityFile /home/jdoe/.ssh/id_dsa
ForwardAgent no
Host *.loria
User jdoe
ProxyCommand ssh accessloria "nc `basename %h .loria` %p"
IdentityFile /home/jdoe/.ssh/id_dsa
With that setup, you can now use :
- Rsync to synchronize your data on Inria/Loria environment and data on your local home on Talc frontend
- Sshfs to mount directly your data directory on Inria/Loria environment under your local home.
eg:
|
| ftalc:
| sshfs -o idmap=user jdoe@tregastel.loria:/users/myteam/jdoe ~/remote_dir |
To unmount the remote filesystem:
|
| ftalc:
| fusermount -u ~/remote_dir |
|
| Note |
|---|---|
The password for your Inria/Loria account will be asked twice if you don't specify a ssh key. | |

- Without permission, any user experiments on the cluster do not must take more than 3840hours for CPU (eg: 10 nodes for 48hours).
