General Notes

 MPI startup command:
   mpirun command was used to start MPI jobs. This command starts
   an independent ring of mpd daemons, launches an MPI job, and shuts
   down the mpd ring upon the job termination.
   The mpirun command automatically detects if an MPI job is submitted
   in a session allocated using a job scheduler (like PBS Pro). In this
   case, the mpirun command extracts the host list from the respective
   environment and uses these nodes automatically.

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

 RAM configuration:
   Compute nodes have 1x4-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 ranks, 2 switches for 256 ranks, 4 switches for 512 ranks.

 Fileserver:
   Intel SR1560SF systems connected via IB to DataDirect Networks S2A9900
   storage which is: 160 disks, 300GB/disk, 48TB total, 35TB available.

 PBS Pro was used for job submission. It has no impact on performance.
