The HPC Center within Research Computing currently maintains the following resources for calculations requiring large amounts of physical memory.

  1. 21 Intel (E5462, 8x 2.8 GHz cores) servers with 64 GB of RAM (physical memory)
  2. 1 Intel (X7560, 16x 2.2 GHz cores) server with 128 GB of RAM.
  3. 1 AMD (Opteron 6174, 48x 2.2 GHz cores) server with 512 GB of RAM
Large Memory Servers
Host Architecture Processor Cores RAM (GB)
r12a-s38 emt64 Intel X7560 16 128
r12a-s40 amd64 Opteron 6174 48 512

The 128 GB and 512 GB machines are available only via a restricted queue (bigmem). To submit jobs to this queue you will need to add the #PBS -q bigmem directive to your job script or use "-q bigmem" option on the qsub command line.

Before attempting to run jobs via the bigmem queue, you should request access to the bigmem queue via a support request ( Please also be aware that memory is not free and servers with hundreds of gigabytes of RAM are still fairly expensive. For this reason and so that resources can be allocated fairly, resource requests are considered on the basis of processor equivalents.
