I've run into an interesting problem with both MPICH.NT and MPICH2 on
Windows 2003 R2. With MPICH.NT our application, given N processors
across M machines, will have at most 2 processes going at once (across
all machines). On MPICH2, if the N processors span more than one machine
nothing happens. Process 0 can make forward progress, but no other
machines talk to one another, which is similar to the problem we are
seeing with MPICH.NT, but not quite the same.
