[mpich-discuss] Problems to run MPI and a Windows 7 64 bits computer

[Hiatt, Dave M]

For whatever it's worth, I'm running 1.2-1.p1 on Windows 7 x64 with no problem, compiling x64 and Win32 modes both, and the apps are running fine.  Did install the 32 bit wmpiexec, wmpiregister, and wmpiconfig from the 32 bit version.  One point to note if you've done that is to make sure you have the proper x64 version of smpd running after putting the x32 version on.  We now make sure that we install that version first, to get those utilities, and then install the x64 and run smpd -install on that, so there are not hiccups.  That mistake did bite us early on.

Hi,
I installed mpich2-1.2-1p1-win-x86-64.msi version of MPICH2.
My program is compiled in 32 bits (but it works on the same computer without in scalar mode).

Any problem to run a non-MPI program

I didn't try to compile and run any simple MPI program on this computer because I didn't have any development environment on it!


In my makefile, I just have a link to the library "fmpich2.lib" and a path to the include directory.
Regards

Christophe

Hi,
 Did you install x64 (64-bit) version of MPICH2 ? Which version of MPICH2 are you using ? Is your application 64-bit ?
 Can you run a non-MPI program (mpiexec -n 2 hostname)?
 Can you compile/run a simple MPI hello world program (https://svn.mcs.anl.gov/repos/mpi/mpich2/trunk/examples/hellow.c)?

(PS: When copying the error message it is helpful to copy-paste the command and the entire command output.) Regards, Jayesh

Hi 



I'm meeting some problems to run my code (Telemac) with MPICH2 on W7 64b 

This software runs for a long time with MPICH2 on XP without any problems. 

On W7, after a long search on internet, I finally install MPICH2 (successfully?). 

The first problem with the SMPD is solved. 

But now I have a new problem in the execution. 

I obtain a message "Unable to open the HKEY_LOCAL_MACHINE\SOFTWARE\MPICH\SMPD\process\1164 registry key, error 5, access denied". 

But I also obtain a message box that indicates me "Impossible to start the program because fmpich2.dll is missing on your computer. Try to re-install the program to solve the problem" 

I check my computer and fmpich2.dll exists in c:\windows\system32. 



Anyone has an idea? 



Regards 



Christophe
