You will need to do this explicitly.

MPI is a standard API for running parallel programs.  MPICH is a 
commonly used implementation of that standard.  Condor supports MPICH, 
but you must explicity design your program to call the various MPI 
routines.

Depending on your job, it may be easier to break your one big job into 
many smaller, independent jobs, and submit those many jobs to Condor all 
at once.  Condor will then run those jobs on as many machines as it can.
