  • 1 node with 2 x CPU Intel Xeon L5640 2.27 GHz (12 cores), 48 GB of RAM, 2 x 140 GB HD SAS (connected in Raid 1), 2 x 1 TB HD SATA (connected in Raid 1), OS Red Hat Enterprise Linux release 5.5.
  • 1 node with 4 x CPU AMD Opteron 6282 SE (32 cores), 256 GB of RAM, 5 x 600 GB HD SAS (connected in Raid 5 + spare disk), Infiniband, OS Red Hat Enterprise Linux release 5.5.

for a total of 2 nodes, 64 cores.


Access

The Pierre cluster is being migrated to the new system. Access information will be updated as soon as the migration is complete.
