| | Update: 21 Sept 09 |
| | |
| | Cluster sharptail has undergone some changes. Courtesy of ITS, 2 more blade enclosures have permanently been added. Another 3 blade enclosures have temporarily been added (destined for another ITS project so they may disappear in the future but in the meantime I figure it could be put to good use). That means |
| | |
| | Cluster sharptail has 129 compute nodes, 258 job slots, and a total memory footprint of 2,328 GB Cluster swallowtail has 36 compute nodes, 288 job slots, and a total memory footprint of 244 GB |
| | |
| | On cluster sharptail, four queues have been set up. Also, Gaussian optimized for AMD Opteron chips as well as a Linda version are available. |
| | |
| | https://dokuwiki.wesleyan.edu/doku.php?id=cluster:73#gaussian |
| | |
| | We’ll have some documentation soon, but in the meantime there are links to resources on the web. |
| | |
| | Queue ‘bss12’ and ‘bss24’ are comprised of nodes with either 22 GB or 24 GB of memory per node (2 single core CPUs). When using Linda, the target node names need to be listed (somewhat silly) instead of letting the scheduler find free nodes. So queues ‘bss12g16’ and ‘bss24g16’ have been set up with 8 predefined hosts each. These queues will not accept jobs requiring less than 16 job slots, the idea being you submit Linda jobs with #BSUB –n 16 and %NProcs=16. |

| The operating system is **[[http://centos.org|CentOS]]**, version 5.3 at this time. This is much like Redhat but not completely. All software compiled in /share/apps has been compiled under RHEL 5.1 and hence may not work in CentOS 5.3. We will recompiled software when requested and post it in /share/apps/centos53 ... all commercial software will only run on petaltail and swallowtail. | The operating system is **[[http://centos.org|CentOS]]**, version 5.3 at this time.

| The scheduler is **[[http://hpccommunity.org|Lava]]**, that is, a recent version of LSF but not the latest. All regular commands for submitting jobs work the same way. The only difference is the advanced queue settings are missing like fairshare, pre-emption, backfill etc. | The scheduler is **[[http://hpccommunity.org|Lava]]**, that is, a recent version of LSF but not the latest.

| If one or more libraries are missing, you could run this command on petaltail or swallowtail, observe were the libraries are located, and if they exist on sharptail, add that path to LD_LIBRARY_PATH. Otherwise the programs need to be recompiled if they are supported on CentOS 5.3 x86_64. | If one or more libraries are missing, you could run this command on petaltail or swallowtail, observe were the libraries are located, and if they exist on sharptail, add that path to LD_LIBRARY_PATH.
