The name of the Phase II system is seaborg.nersc.gov . It consists of 158 IBM Nighthawk II 375 MHz 16-way SMP nodes with a Colony switch that allows 16 MPI tasks per node. Slots one through four of the Top 500 list are occupied by ASCI machines at DOE's three defense labs. These 140 nodes have 12 GB of memory each. The 16 GPFS nodes and 2 network nodes each have 8 GB of memory.
Current availability is regularly updated below.
Current Queue Status Access is available through ssh only. On first login ssh to sadmin.nersc.gov to change your password. After one hour the changes should propagate out. While very similar to the phase I system, gseaborg, there are several differences which should be noted. You may also wish to investigate OpenMP More memory, 12GB per node.
