Submit Notes

The config file option 'submit' was used.
For benchmarks that used 2048 or 2560 MPI ranks, four ranks
were assigned to each CPU chip, leaving 2 cores per chip idle.

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 080016
   Hyper-Threading Technology enabled (default)
   Intel Turbo Boost Technology enabled (default)
   Intel Turbo Boost Technology activated in the OS via
     /etc/init.d/acpid start
     /etc/init.d/powersaved start
     powersave -f

 Job Placement:
   In the run with 3072 and 4608 ranks, each MPI job was
   assigned to a topologically compact set of nodes with
   64 switches for 3072 ranks and 96 switches for 4608 ranks.
   In the run with 2048 and 2560 MPI ranks, four ranks were
   assigned to each CPU chip, leaving 2 cores per chip idle.
   There were 64 switches used for 2048 ranks and 80 switches
   used for 2560 ranks, with topology compact configurations
   in both cases.

 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).
