Two new LinuxBIOS-based clusters at LANL
LANL is installing two new LinuxBIOS-based K8 clusters, Blue Steel (a.k.a. Orange) and Lighting. Both also use the Bproc 3.0 software, available at the clustermatic site. Blue Steel has a 288-port Infiniband interconnect from Mellanox Networks. Lightning has a 2048-port Myrinet interconnect. Blue Steel will run in 64-bit mode; Lightning will run in 32-bit mode. Both systems are from Linux NetWorx and use the Evolocity packaging. Note that both systems have more ports than nodes so that other systems can be cabled into the network backplane as needed.
This was reported on Slashdot a while ago, but today the cluster is finally being installed (Just got done eating lunch with the Linux Networx team, in fact). Why the larger cluster, Lightning, will only run in 32-bit mode I don't know. Lightning is the production cluster, Blue Steel is the R&D cluster.
I'd also like to add that Linux Networx is a great bunch of people
