[Wien] MPIRUN command

[Valerie Base]

 Hello,


In the command: mpirun -np _NP_ -machinefile _HOSTS_ _EXEC_


does _NP_ denote the number of processors and _HOSTS__EXEC denote the host
list? Is the host list the same as the .machines file.

The system that I'm running WIEN2k on launches MPI job in a slightly
different way (ibrun is used instead of mpirun) so knowing how WIEN2k
launches MPI jobs will aid my sys. admin help me.

Thank you.
