I just cross-verified the timestamps of the dlls and they look alright. Make sure that you have the date/timestamps right on all the hosts involved.<BR>

Hi,<BR>
I spoke too soon. We have discontinued supporting sshm channel and that<BR>
is the reason that you have an old version of sshm related dlls in your<BR>
system32 directory.<BR>
<BR>

Jayesh<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>

Hi Jayesh,<BR>
<BR>
Great to hear from you. I will try your suggestions (icpi.c and slow<BR>
response).<BR>
<BR>
Also here is the output you requested. I have been wondering why the<BR>
dates on mpich2sshm.dll and mpich2sshmp.dll seem so old (from 2005)???<BR>
...I should have mentioned it sooner.<BR>
<BR>
Thanks,<BR>
Tim<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>

Jayesh<BR>

The socket/channel connection between the MPI processes take place<BR>
during<BR>
MPI_Bcast() (not before that in fpi.f).<BR>

The firewall has been disabled.<BR>
<BR>
The inputs were from me entering values for estimating pi...I wanted to<BR>
make sure the program ran through all the logic.<BR>
<BR>
I will send the other debug output a little later.<BR>
<BR>
Also, as an fyi, we have been running MPICH on thousands of PC's for<BR>
years now. The other strange part is that over a year ago I did<BR>
successfully run MPICH2 on over 30 processors. My first thought was<BR>
the<BR>
firewall as well.<BR>

The setup is homogenous (both 32-bit). The output is attached.<BR>

you specify ipaddresses of the hosts involved),<BR>

No this does not work...the behavior is the same. The UNC's<BR>
should/have<BR>
worked regardless of whether a user a user is logged in. We have never<BR>
relied on drive network drive mappings since they are intermittently an<BR>
"interactive" feature.<BR>

You should try,<BR>

mpiexec.exe -map y:\\hostA\temp -hosts 2 hostA hostB y:\fpi.exe<BR>
<<A HREF="file://hosta/temp/fpi.exe">file://hosta/temp/fpi.exe</A>><BR>

Let us know if it works for you.<BR>

(PS: The shared drive is accessible across machines because the drive<BR>
is<BR>
accessible/mapped by the user logged on to the machines. SMPD runs as a<BR>

The exe can be directly accessed from hostB by executing<BR>
\\hostA\temp\fpi.exe, that is, you could type it directly into a<BR>
command<BR>
prompt from hostB if you wanted. Note also that \temp directory is a<BR>
shared location. I am not sure physically how this is setup on our<BR>
network but this has worked with out any "mapping" for MPICH (MPICH1).<BR>
<BR>
Note: I did try: mpiexec.exe -map y:\\hostA\temp -hosts 2 hostA hostB<BR>
\\hostA\temp\fpi.exe but that still hangs in the MPI_Bcast call.<BR>
<BR>
The interesting part is that it gets through the initialization:<BR>
<BR>
call MPI_INIT( ierr )<BR>
call MPI_COMM_RANK( MPI_COMM_WORLD, myid, ierr )<BR>
call MPI_COMM_SIZE( MPI_COMM_WORLD, numprocs, ierr )<BR>
<BR>
<BR>
All execute.<BR>
<BR>

Thanks Jayesh for the quick reply. This is a network availabe UNC path<BR>
-<BR>
why do I need to map a drive?<BR>
<BR>
I am familiar with the machines file - I was just using the command<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>
Regards,<BR>
Jayesh<BR>

Component: mpich2 |<BR>

<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>
<\\hostA\temp\fpi.exe><BR>
<BR>
mpiexec.exe -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 \\hostA\temp\fpi.exe<BR>
<\\hostA\temp\fpi.exe><BR>
<BR>
<BR>
Any suggestions would be appreciated. Also let me know if you want<BR>
me<BR>
to<BR>
send debug output.<BR>
<BR>
Thanks,<BR>
Tim<BR>
