| Switch Model: | SGI QDR_1.5_HYPR_2454 with Mellanox Device 48438 (Infiniscale IV) |
| Number of Switches: | 64 |

| Firmware: | 5040005 |
| Topology: | Enhanced Hypercube |
| Primary Use: | MPI and I/O traffic |
The config file option 'submit' was used. For peak benchmarks that used 2048 MPI ranks, four ranks were assigned to each CPU chip, leaving 2 cores per chip idle.
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 base run, each MPI job was assigned to a topologically compact
set of nodes, i.e. the minimal needed number of switches was
used for each job: 2 switches for 96 ranks,
4 switches for 192 ranks, 8 switches for 384 ranks,
16 switches for 768 ranks, 32 switches for 1536 ranks,
and 64 switches for 3072 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.
