[mpich-discuss] No requirement for smpd.exe in MPICH2-1.3.3

[Robert Hunter]

Jayesh,

I believe the problem may lie in the fact that the smpd needs to write to the registry in HKEY_LOCAL_MACHINE, which I don't have permission to write into. I tried the same steps outlined below on a machine that I do have permission to write into HKEY_LOCAL_MACHINE and I was able to run.

Do you know of anyway to override the default value of the registry key? In looking through the source I couldn't find any. Perhaps future versions could allow for registry entries to be written to HKEY_CURRENT_USER?

Thanks,

Bobby

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:

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?
