VT SGI System Descriptions
VT ARC currently has three SGI Enterprise
ALTIX 3700 Superclusters which provide Virginia Tech researchers with
access to high performance computing on SGI hardware:
| Hostname | CPUs-Speed | Memory | Operating System |
inferno.cc.vt.edu | 20-1.3 GHz | 32 GB | SLES10-ProPack5 |
inferno2.cc.vt.edu | 128-1.6 GHz | 512 GB | SLES10-ProPack5 |
cauldron.arc.vt.edu | 64-1.5 GHz | 320 GB | SLES10-ProPack5 |
A queuing system, similar to what SystemX uses, is currently
implemented on Cauldron and will also be made available on Inferno2 in
the near future. Until then, please follow these guidelines when
submitting your jobs.
| inferno |
- short running jobs not to exceed 4 hours
- memory requirements (1 GB per processor)
|
|---|
| inferno2 |
- long running jobs
- memory requirements (1-4 GB per processor)
|
|---|
| cauldron |
- long running jobs
- memory requirements (1-5 GB per processor)
|
|---|
If you require a large number of processors (up to 128) special
arrangements will be made. A brief writeup on the project and
a summarization of results are required. Please contact either
Dr. Terry Herdman or
Dr. Kevin Shinpaugh
for these needs.
The special scheduling for runs, requiring large numbers of
processors, may take an extended period. Active jobs will have
to finish, or be stopped, and new jobs submitted on an alternate
system. Please make alterations to all jobs, so they are restartable
at a check point, to prevent the loss of previous calculations.
