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

[Jayesh Krishna]

Hi,
 We would recommend that you migrate to MPICH2. All of our current
development efforts are going into MPICH2.
 Meanwhile, do you have the same problem with OS flavors other than Win 2003
R2 ? Do you see the same problem with sample MPI applications like cpi.c ?
 
Regards,
Jayesh

(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.
