 In cases when not all CPUs of one node are required, the machines file can be modified to guarantee the right behaviour of mpirun. The $TMPDIR/machines file on VSC-1 consists of a number of machine/node names. Each name stands for one CPU on the given machine/node. For an exclusive job on 2 nodes the machine file looks like: In cases when not all CPUs of one node are required, the machines file can be modified to guarantee the right behaviour of mpirun.
