Comment (by Jayesh Krishna):<BR><BR> Hi,<BR>
Hmmm... This looks like the problem that I mentioned in my
email.<BR> *sshm*.dll s should have the same datestamp as other dlls
(should not be<BR> from 2005!).<BR> Please try the
following,<BR><BR> # Uninstall MPICH2 on the hosts involved in your
job.<BR> # Manually delete the MPICH2 dlls from windows\system32
directory (Please<BR> be careful! Make sure that you delete only
mpich2*.dll & mpe*.dll) #<BR> Re-install MPICH2 1.0.7 (stable
version) on the hosts/nodes .<BR> # Re-compile cpi.c/fpi.c and try
running your job.<BR><BR> Let us know the
results.<BR><BR> Regards,<BR> Jayesh<BR><BR>

Krishna):<BR><BR>
Hi,<BR> The logs sent by you show that the
communication btw the process<BR> managers on the hosts
is good. The problem looks to be with the<BR>
communication btw the MPI processes.<BR><BR> # Can you
try compiling icpi.c (MPICH2\examples) and run the program
in<BR> your setup (Make sure that the problem is not
related to fortran<BR>
bindings).<BR> # I have seen that some times that the
uninstall/install of MPICH2 does<BR> not result in
the dlls being updated correctly (This has lead to
some<BR> wierd-difficult-to-debug hangs in our tests.
This is not usual but it<BR> does<BR> not hurt to
check for it though). To make sure that you have the
right<BR> dlls try listing the MPICH2 dlls in your
windows system32 directory on<BR> both the
hosts,<BR><BR> >>> dir
c:\windows\system32\mpich2*.dll<BR> >>> dir
c:\windows\system32\mpe*.dll<BR><BR> Send us
the results for verification (Sanity check- they should have<BR>
the<BR> same datestamp)<BR><BR>
# Also when running fpi.exe using your setup try leaving the job (or<BR>
may<BR> be specify a timeout of 10 mins or so) for
10mins or so and see if it<BR> reports any errors. You
might want to run netstat (or use "Process<BR> explorer"
from microsoft and check the TCP/IP tab in the<BR>
process->properties) to see what happens to the connections btw the
MPI<BR> processes from both
hosts.<BR><BR> (PS: The MPICH2 1.1.0a1
release<BR><BR><BR> (<A
href="http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=dow">http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=dow</A><BR>
nloads) is aimed at MPICH2 devs and not for production machines.
)<BR><BR> Regards,<BR>

Hi,<BR> If you are running your executable
from a shared network drive you<BR> need<BR> to
map (see "--map" option of mpiexec in the window's developer's<BR>
guide)<BR> the network drive with mpiexec when launching
your job.<BR> Also make sure that you have
turned the windows firewall (or any<BR> other<BR>
firewalls) off on the machines involved in the
job.<BR> Try specifying the ip addresses of
the machines instead of the<BR>
hostnames.<BR> Let us know the
results.<BR><BR> (PS: Instead of the "-hosts" option you
could try using the<BR> "-machinefile"<BR> option
available with mpiexec. See the window's developer's guide
for<BR> details.)<BR><BR>

I am testing MPICH2 MPICH2-1.0.7 Windows XP (sp2). I have
installed<BR> it<BR>
on<BR> 2<BR> hosts
(hostA, hostB) and trying to run the fpi.exe built
with<BR> fmpich2.lib.<BR>
The code is hanging in a MPI_Bcast call. The fpi.exe source is<BR>
attached.<BR><BR> The following tests work fine
from hostA, both prompt for a number of<BR> intervals,
accept input, and produce and estimate of
PI<BR><BR> mpiexec.exe -hosts 2 hostA hostA
\\hostA\temp\fpi.exe<BR>

-hosts 2 hostB hostB \\hostA\temp\fpi.exe<BR>
<\\hostA\temp\fpi.exe><BR><BR><BR><BR> The
following test hangs when submitted from hostA (in
MPI_Bcast).<BR> It<BR> does prompt for input
(number of intervals) but once entered it hangs.<BR>
I<BR> have launched the smpd process using smpd -d
but see no output from<BR> the<BR> smpd
after I enter an interval value<BR><BR>
mpiexec.exe -hosts 2 hostA hostB

want<BR> me<BR>
to<BR> send debug
output.<BR><BR>
