Submit Notes

The config file option 'submit' was used.

General Notes

 MPI startup command:
   mpiexec.hydra command was used to start MPI jobs.

 BIOS settings:
   Intel Hyper-Threading Technology (SMT): Enabled (default is Enabled)
   Intel Turbo Boost Technology (Turbo)  : Disabled (default is Enabled)

 RAM configuration:
   Compute nodes have 2x8-GB RDIMM on each memory channel.

 Network:
   Forty six 36-port switches: 18 core switches and 28 leaf switches.
   Each leaf has one link to each core. Remaining 18 ports on 25 of 28 leafs
   are used for compute nodes. On the remaining 3 leafs the ports are used
   for FS nodes and other peripherals.

 Job placement:
   Each MPI job was assigned to a topologically compact set of nodes, i.e.
   the minimal needed number of leaf switches was used for each job: 1 switch
   for 16/32/64/128/256 ranks, 2 switches for 512 ranks, 4 switches for 1024 ranks,
   8 switches for 2048 ranks.

 Platform LSF was used for job submission. It has no impact on performance.
