Hi,
 Try copying the *.dlls to C:\mpich2\bin and let us know if it works.

Regards,
Jayesh

Jayesh, 


Thanks for the information regarding smpd.exe. 


I still have a question as to how I would run without installing smpd. I've tried the following: 
I copied smpd.exe, mpiexec.exe to a dir named C:\mpich2\bin, I then added this dir my to my PATH. I also copied mpich2mpi.dll, mpich2nemesis.dll, and cpi.exe to C:\mpich2 . I then unistalled mpich2-1.3.3rc1 and rebooted. Next I tried the following in the c:\mpich2 dir ".\bin\mpiexec.exe -localonly 2 cpi.exe" The following output is what I get: 

C:\mpich2>.\bin\mpiexec.exe -localonly 2 .\cpi.exe 
Unknown option: -d 
Error while connecting to host, No connection could be made because the 
target machine actively refused it. (10061) 
Connect on sock (host=bhunter-lt.erdc.hpc.mil, port=8676) failed, 
exhaused all end points 
Unable to connect to 'bhunter-lt.erdc.hpc.mil:8676', 
sock error: Error = -1 

ReadFile() failed, error 109 
unable to start the local smpd manager. 


C:\mpich2> 




Note: I don't have admin privileges on the machine. 


Thanks for any help.

Hi, 
MPICH2 1.3.3 did not remove the requirement for smpd.exe . 
When using the "-localonly' option with mpiexec you do not need to have SMPD installed on the system. MPICH2 1.3.3 removed firewall issues when starting MPI jobs with the "-localonly" option. 
So you still need SMPD to be available, but you don't need to install SMPD or worry about firewall issues when running all MPI processes on the local node.

I came across a note @ boinc.berkley.edu that stated mpich2-1.3.3 should remove the requirement for smpd.exe, as well as no firewall issues on Windows. I've downloaded and tried this method with the mpich-1.3.3r1-win-ia32 install and using the following command line "mpiexec -localonly -n 2 -channel nemesis:none cpi.exe" but it simply returns the following error "Uknown option -d". Will these functionality be included in the MPICH2-1.3.3 release? 

Thanks, 

Bobby
