Numactl (MAP)

MAP supports launching programs via numactl for MPI programs. It works with or without SLURM. The recommended way to launch via numactl is to use Express Launch (MAP).

map mpiexec -n 4 numactl -m 1 ./myprogram.exe
map srun -n 4 numactl -m 1 ./myprogram.exe

It is also possible to launch via numactl using compatibility mode. When using compatibility mode, you must specify the full path to numactl in the Application field of the Run dialog . You can find the full path by running:

which numactl

Enter the name of the required application in the Arguments field, after all arguments to be passed to numactl. It is not possible to pass any more arguments to the parallel job runner when using this mode for launching.
