[mpich-discuss] MPICH2 On Windows 64 bit and Mingw-w64 compilers

[Jayesh Krishna]

Hi,
 Can you try running the job from an administrator command prompt (Note that opening a command prompt from an administrator account does not give you an admin command prompt. Right-click on the command prompt icon and select "Run as administrator" to get an admin command prompt) and see if it works ?
 Can you also check the status of the MPICH2 process manager (Type "smpd -status" at the command prompt)?

Regards,
Jayesh

Hi Jayesh

I tried that. It did not help. Here is the response:

"
C:\tmp>"C:\Program Files\MPICH2\bin"\mpiexec.exe -n 2 -localroot icpi.exe

Unable to open the HKEY_LOCAL_MACHINE\SOFTWARE\MPICH\SMPD\process\6308 
registry key, error 5, Access is denied.
Unable to open the HKEY_LOCAL_MACHINE\SOFTWARE\MPICH\SMPD\process\808 
registry k ey, error 5, Access is denied.
"

When I killed the job by <CTRL> C, the following messages appeared:

"
mpiexec aborting job...
received suspend command for a pmi context that doesn't exist: unmatched 
id = 1

job aborted:
rank: node: exit code[: error message]
0: Arun-PC: -1073741819: mpiexec aborting job
1: Arun-PC: -1073741819
Terminate batch job (Y/N)? y
"

When I tried the same thing on the pre-built "cpi.exe", I get the same 
messages that I got with "icpi.exe", but it still works:

"
C:\tmp>"C:\Program Files\MPICH2\bin"\mpiexec.exe -n 2 -localroot cpi

When I killed this job by <CTRL> C, the following messages appeared:

Does it have anything to do with an incorrect node (-1073741819) on 
which mpiexec is trying to launch the processes? Thanks for your help.

Best Regards
Arun
