Hello. I currently administer and write software for an 8 node cluster at the Naval Surface Warfare Center in Bethesda MD. All of our machines have AMD 1000MHz processors, dual 80GB ATA100 Raid 0, 512 MB PC 133, and 3Com 100bT NICs. We are running Red Hat 7.1, which uses kernel 2.4.2. As of yesterday, the entire cluster, which is used for production work almost daily, had an uptime of 99 days. The software I have written uses lam-mpi for communication. The software is for high volume data analysis, of ship and submarine test data, in the time and frequency domains, which is very network, memory, and cpu intensive. Because of our software design and the size of the data files, we have not experienced heavy swapping, so I cannot comment on the speed or stability of the VM portion of the kernel. Some of our analysis jobs take 6-8 hours to complete at 99.9% cpu load on the compute nodes. I am pleased with 2.4*.
