16 full cores are requested and 2 GPUs. The 16x4 (virtual) cpus are used for 4 MPI tasks and 16 OMP threads per task. The -m flag in the srun command specifies the desired process distribution between nodes/socket/cores (the default is block:cyclic). Please refer to srun manual for more details on the processes distribution and binding. The --map-by socket:PE=4 will assign and bind 4 physical consecutive cores to each process (see process mapping and binding on the official IBM Spectrum MPI manual).

Here you can find Other batch job examples on M100 . You can find more information on process mapping and binding on the official IBM Spectrum MPI manual.
Graphic session
If a graphic session is desired we recommend to use the tool RCM (Remote Connection Manager). For additional information visit Remote Visualization section on our User Guide.
