Description
Dalton is a small cluster featuring both IBM Power PC and Intel Xeon CPU's. It is equipped with the following hardware/software:
- 8 nodes with 2 x CPU Ibm PPC6 (8 cores), 24 GB of RAM, 1 x 140 GB HD SAS, Infiniband, OS Red Hat Linux Server Enterprise release 5.3.
- 6 nodes with 2 x CPU Intel Xeon X5650 2.6 GHz (12 cores), 48 GB of RAM, 2 x 300 GB HD SAS, Infiniband, OS Red Hat Linux Server Enterprise release 5.5.
for a total of 14 nodes, 208 cores.
Access
- Linux and Mac OS users can login using a terminal with the command:
ssh account@192.168.9.14
- 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 LL for the IBM nodes and PBS for the Intel nodes. The following queues are available:
- dalton-IBM: max nodes 8, max walltime 2 weeks (336 hours)
- b: max nodes 6, max walltime 2 weeks (336 hours)
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 dalton-intel #PBS -l nodes=n #PBS -w time in hh:mm:ss format commands to execute
while a typical LL input file script will be as follow (see the Support page for more help):
TODO commands to execute
where the parts in italic should be changed as appropriate.
