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.</FONT></SPAN></DIV>

and MPICH2 issue on Windows 2003 R2<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV><SPAN class=052263014-19072007><FONT face=Arial size=2>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.</FONT></SPAN></DIV>
