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 |
Inferno2 and Cauldron are accessed via a queuing system via the head
nodes charon1.arc.vt.edu or charon2.arc.vt.edu, see details SGI Queuing System.
Direct logins to an SGI Altix interactive node, inferno.arc.vt.edu, are available. It is to be used for applications requiring interactive sessions (such as GUIs) and for debug purposes. This is a relatively small server: please do not run large jobs on inferno; try to limit debug jobs on inferno to 2 - 4 processors.
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.
