How are the clusters being used?
The small cluster, Anchorage, has proven effective for testing, debugging, and small model runs for scientific research. The new cluster, Bangkok, currently (25Nov03) has network limitations that prevent performance from scaling past 16 processors (8 nodes). Until upgrades can be fitted, it is expect to provide a similar role as Anchorage, with the added benefit of more job capacity. Calgary (26Jan04) is similar to Bangkok in hardware, with the addtion of Infiniband as the network fabric. Currently only 8 nodes are attached. As budget becomes available, nodes will be moved from Bangkok and attached to Calgary.
