[mpich-discuss] Hydra process manager on Condor

[Pavan Balaji]

Hydra does not understand Condor's parameters.  But you can emulate the 
behavior you want by setting these options for mpiexec:

  -outfile-pattern ho.out -errfile-pattern he.err

You can also do more fancy things like:

  -outfile-pattern ho.%r.out -errfile-pattern he.%r.err

which uses different files for each rank.

See mpiexec -outfile-pattern -help for more information on other patterns.
