General Notes ------------- MPI startup command: mpiexec.hydra command was used to start MPI jobs. 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 2x8-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 40/80/120/160 ranks. PBS Pro was used for job submission. It has no impact on performance.
