Our original but still operational Beowulf cluster was first brought online in 2005. The original cluster had 48 nodes and as of July 2020 there are still 18 nodes plus the master in operation. In comparison, each of those original nodes included dual 2GHz 64 bit AMD Opteron 246 (K8 Sledgehammer) processors and 1GB of RAM (although now several nodes have been upgraded to 2GB of RAM from the RAM of non-functional nodes.) This cluster was built as a farm of dual socket tower servers from Aspen Systems interconnected with a standard 1Gbps ethernet switch. This cluster was primarily used to run CitCom finite element analysis by students and researchers working with Professor Slava Solomatov.
