General Notes

 Software environment:
   export MPI_REQUEST_MAX=65536
   export MPI_TYPE_MAX=32768
   export MPI_BUFS_THRESHOLD=1
   export MPI_IB_RAILS=2
   ulimit -s unlimited

 BIOS settings:
   AMI BIOS version 2.0

 Job Placement:
   In the base run, each MPI job is assigned to a topologically compact
   set of nodes, i.e. the minimal needed number of switches was
   used for each job: 2 switch for up to 256 ranks, 4 switches
   for 512 ranks, 8 switches for 1024 ranks.

 Additional notes regarding interconnect:
   The Infiniband network consists of two independent planes,
   with half the switches in the system allocated to each plane.
   I/O traffic is restricted to one plane, while MPI traffic can
   use both planes.

   SGI manufactures its own switch blades using unmodified Mellanox
   switch ASICs. The test system has SGI QDR_1.5_HYPR_2454 switch
   with Mellanox 36-port QDR Infiniband switch Device 48438
   (InfiniScale IV).
