Techstaff details about this are here

Fortran:
• Makefile (example)
• bsort.pf
C:
• Makefile (example)
• dsum.pc

make (after downloading above files)

prun N mchf [other-mpirun-arguments] program-name [arguments]
prun 3 N mchf -v -t ./bsort

 or 

mpirun -np N -machinefile mchf program-name [arguments]

(mpirun -np 3 -machinefile mchf ./bsort)

where mchf must be a file listing available computers (in our case):

• Don't forget stop at the end of Fortran programs (see the example)
• Be sure following commands are whorking whitout asking the password:
  > ssh union ls
  > ssh the-400 ls



• Use this script (it will be incoporated in prun) for testing the list of available machines at a given moment if your application is not starting (save it as checkm and run: "chmod 755 checkm; checkm mchf"). All are running 24/7, but ...
