Sapelo decommissioned

The original Sapelo cluster (sapelo1.gacrc.uga.edu) is now fully decommissioned and all nodes that were originally part of Sapelo were migrated into Sapelo2.


New hardware added into Sapelo2

In addition to the nodes that were originally part of Sapelo, we have added the following new hardware into Sapelo2:

  • 44 compute nodes with Intel Xeon Skylake processors (32 cores and 188GB of RAM per node)
  • 4 compute nodes with Intel Xeon Skylake processors (32 cores and 188GB of RAM) and 1 NVIDIA P100 GPU card per node
  • DDN SFA14KX Lustre appliance (1.26PB), serving /scratch and /work areas
  • An EDR Infiniband network that provides internodal communication among a subset of compute nodes and between these nodes and the storage devices serving the users home directories and the scratch and work directories. The subset of nodes that are connected to the EDR IB fabric are the new Intel Skylake nodes and and Intel Broadwell nodes that were already on Sapelo2.


Changes in the storage systems on Sapelo2
