SM Nodes

IBM3755.jpg

We have 11 IBM System X3755 M3 nodes for high memory jobs. These nodes have been restricted to only allow jobs which utilise at least 256GB RAM.

SM IBM System X3755 M3
Count 11
Processor 4 x 12 Core AMD Opteron 6234 (Bulldozer)
Cores/Node 48
RAM 512GB
TMP Size 1.9TB
Interconnect 10Gb Ethernet

Notes

  • On a core-by-core comparison, the sm nodes have the slowest individual core speed. Avoid excluding your jobs from faster nodes due to restrictive configuration options (too much memory requested vs memory used, specifying a specific node_type). If your jobs regularly require large memory requirements, consider optimisation or splitting the job into smaller components.
  • sm nodes also have the largest local temporary folder space. Using tmpdir rather than central storage can result in considerable performance improvements.
