MPICH2 that I have installed is the 64-bit version. My computer has
windows 7, is a 64-bit operating system, and has an intel core i5 CPU

I think that the issue is still that MPICH2 was not installed
correctly in your system (I verified that 1.4.1p1 works correctly -
without error msgs - on our Srv2008). Please follow the steps below and
let us know if it works for you,<br>
<br>
# Right-click on the command prompt icon and select "Run as

# From the admin command prompt, uninstall SMPD using the "-uninstall"

# Try running mpiexec from a normal command prompt (Type "mpiexec -n 2

Yes, please give us the output of the command with "-verbose" turned on.<br>
And for these tests, run mpiexec with the complete path ("c:\Program

Hi,<br>
<br>
1. Make sure that the process manager, smpd, is running in your system
(Look in the task manager/Process Explorer to see if there is a service
named smpd running. Alternately you can run "smpd -status" to check if
smpd is running)<br>
<br>
2. Run a simple non-MPI program like hostname from the command prompt
using mpiexec (Type "mpiexec -n 2 hostname" ). When prompted for
username/password give a valid Windows username/password.<br>
If mpiexec gives you an error, type "mpiexec -remove" to remove the
existing registered username/password and then type "mpiexec -register"
to register a new/valid Windows username/password. Re-run mpiexec.<br>
<br>
3. Run the sample MPI program, cpi.exe, provided with MPICH2 (mpiexec
-n 2 C:\Progra~1\MPICH2\examples\cpi.exe)<br>
<br>

Alright. I have reinstalled MPICH2 using the method in section 9.4.
However, I am not able to connect to the host it seems. I keep
receiving this message when trying to execute a program:<br>

Also, I am getting an error when I look at the MPICH2 configurable

Hi,<br>
There are two ways you can use MPICH2 on Windows+cygwin,<br>
<br>
# Download MPICH2 source compile/install it on Cygwin. Use mpicc to
compile and use mpiexec (from this installation - NOT the one available
with Windows installer) to run your program.<br>
<br>
# Download MPICH2 Windows installer, install MPICH2 (using installer
gui). Use the cygwin/gcc libs provided with the Windows installation to
compile your code. Use mpiexec from the Windows installation to run
your job.<br>
<br>
Looks like you are mixing the approaches.<br>

Hello,<br>
<br>
I am new to MPI and I went and installed mpich2 1.4.1 onto a windows
system that is being used through cygwin. I have compiled the code that
simply prints the process and rank as shown below.<br>
<br>
<br>
<br>
#include <stdio.h><br>
#include <mpi.h><br>
<br>
int main( int argc, char *argv[]) {<br>
<br>
int numprocs, rank, namelen;<br>
char processor_name[MPI_MAX_PROCESSOR_NAME];<br>
<br>
MPI_Init(&argc, &argv);<br>
MPI_Comm_size(MPI_COMM_WORLD, &numprocs);<br>
MPI_Comm_rank(MPI_COMM_WORLD, &rank);<br>
MPI_Get_processor_name(processor_name, &namelen);<br>
<br>
printf( "Process %d on %s out of %d\n" , rank, processor_name,
numprocs);<br>
<br>
MPI_Finalize();<br>
}<br>
<br>
Nothing too complicated. However, I still receive an error from the
command line in cygwin that simply reads segmentation fault: (core
dumped). The command I used was:<br>
<br>
mpiexec -n 1 a.exe<br>
<br>
No matter what executable I try to run, I still receive the same error.
Any help regarding this would be greatly appreciated!<br>
