[mpich-discuss] Running MPIEXEC on Windows 7

[Alan L Flint]

I have been successfully running all my parallel codes on Windows NT. I've 
had one computer converted to Windows 7 and cannot get mpiexec to run even 
the simple cpi example.  My command in an Adminstrator MS-DOS prompt is:

mpiexec -n 4 cpi

I get back the following error:

Error while connecting to host, No connection could be made because the 
target machine actively refused it. (10061)
Connect on sock (host=igswcawwws1889.gs.doi.net, port=8676) failed, 
exhaused all end points
Unable to connect to 'igswcawwws1889.gs.doi.net:8676',
sock error: Error = -1


I've also run it using wmpiexec and get the same result.  I've allow 
mpiexec and cpi to run under the Windows firewall so I'm not sure what to 
look for in Windows 7.

Thanks.

Alan
