The config file option 'submit' was used.
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. 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).
