Specify "Requirements" in your submit file - the manual has lots
of examples.  E.g.
   Requirements = Machine == "foo.edu" || Machine == "bar.edu"

Another idea: if you can write a script to detect the situation, 
then you can make a 'hawkeye' plugin (see the manual) to enable
condor to automatically detect the problem and automatically not
start MPI jobs on these problem nodes until they are repaired.
