Parallel file system
(PFS)
None None None Traditionally used for temporary files, PFS's are now used for all kinds of storage. Researcher request s for storage are routinely 10 to 20TB, compared to 50 to 100GB two to three years ago

Legend
[1] :

  • Applies also to Cores and RAM
  • Red numbers mean that the nodes are Out of Warranty
  • Green numbers mean that the nodes are In Warranty

[2] : "DMS" refers to the Department of Mathematical Sciences. DMS owns the Stheno cluster.

[3] : "Private Access" refers to cluster hardware purchased by individual researchers. That hardqare is dedicated to those reserachers

High-speed node interconnect and parallel file system

Roles of inetrnal network and PFS

HPC cluster storage

Storage accessible to HPC clusters
