[MPICH] MPICH.NT and MPICH2 issue on Windows 2003 R2

[Watford, Christopher A (GE Infra, Energy)]

(Apologies for the double post, our email system is not the best.)
 
It also appears that I have no problems submitting from host A to host B
to run (solely on host B). I can watch it work fine on host B via the
command prompt on host A (where mpiexec was called). Yet it appears as
soon as I have a job that spans two Win2k3r2 hosts I run into a problem.

	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.
