Description
Pierre is a small cluster made of 2 nodes only, but both hosting a large number of cores and large amount of RAM memory. In particular, it is equipped with the following hardware/software:
- 1 node with 2 x CPU Intel Xeon L5640 2.27 GHz (12 cores), Y GB of RAM, 2 x 140 GB HD SAS (connected in Raid 1), 2 x 1 TB HD SATA (connected in Raid 1), OS Linux Red Hat X.Y.
- 1 node with 4 x CPU AMD Opteron 6282 SE (32 cores), 256 GB of RAM, 5 x 600 GB HD SAS (connected in Raid 5 + spare disk), Infiniband, OS Scientific Linux X.Y.
for a total of 2 nodes, 64 cores.
Access
- Linux and Mac OS users can login using a terminal with the command:
ssh account@192.168.9.##
- where "account" is the user's account.
- Windows users can use an interface program to the ssh service, e.g. Putty.
Queues
The queue manager is PBS and the following queues are available:
- pierre: max nodes 1, max cores 12, max walltime 2 weeks (336 hours)
- x...: max nodes 1, max cores 32, max walltime 2 weekd (336 hors)
Example PBS file
A typical PBS input file script will be as follow (see the Support page for more help):
#!/bin/sh --login #PBS -N jobname #PBS -A account #PBS -q queue #PBS -l nodes=n #PBS -w time in hh:mm:ss format commands to execute
where the parts in italic should be changed as appropriate.
