<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>
