No, it is not going to work out of the box, sorry.  There is a lot of 
extra work that would need to happen that the Condor checkpoint library 
does not deal with (like flushing data in transit on the wire, and 
coordination with the other ranks).

You may want to check out the LAM mpi implementation.  IIRC, LAM 
supports checkpointing with help from the berkely checkpoint library. 
And Condor's parallel universe has been used to manage LAM jobs...

Good luck,
Todd
