Hi Ole,


Thanks for that. I finally managed to get it all working OK on Windows with Visual Studio 2003 and MPICH2.

For info, here’s what I had to do


I changed setup.py line 112 to replace

output = "gcc -L$MPICH_DIR\SDK.gcc\lib -lmpich -I$MPICH_DIR\SDK.gcc\include"


output = "gcc -L$MPICH_DIR\lib -lmpi -I$MPICH_DIR\include"

since using MPICH2 and not MPICH.


Then in compile.py line 112 (as well!?!) I changed the definition of python_include:

            python_include = os.path.join(sys.exec_prefix, 'include')


Then when running setup.py the compile and link commands printed were slightly wrong. I then ran them manually with those corrections:


"C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\cl.exe" /c /nologo /Ox /MD /W3 /GX /DNDEBUG /I%MPICH_DIR%\include /IC:\Python25\lib\site-packages\numpy\core\include /IC:\Python25\include /IC:\Python25\PC /Tcmpiext.c /Fobuild\temp.win32-2.5\Release\mpiext.obj


"C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\link.exe" /DLL /nologo /INCREMENTAL:NO /LIBPATH:%MPICH_DIR%\lib /LIBPATH:C:\Python25\libs /LIBPATH:C:\Python25\PCBuild mpi.lib /EXPORT:initmpiext build\temp.win32-2.5\Release\mpiext.obj /OUT:build\lib.win32-2.5\pypar\mpiext.pyd /IMPLIB:build\temp.win32-2.5\Release\mpiext.lib


After that, setup.py ran fine with the “build” and “install” targets, and I could run a demo example OK.

Hi Thomas


From what you are saying the problem lies with your MPI system.

The first thing to do is to test a simple C or Fortran based MPI program such as network_timing.c or other examples like that.

If that can’t run, there is no point in trying pypar.


Perhaps you could try OpenMPI which seems to be the most developed MPI implementation at present.


I have CC’d this to the pypar mailing list so that others can chime in.

Dear Oli,


I’m trying to install pypar on a windows machine with MPICH and visual studio 2003. I’m not having much luck though

mpirun -np 2 demo.py consistently returns



"C:\projects\pypar_2.1.0_66\demos>mpirun -np 2 demo.py

Unable to launch 'C:\projects\pypar_2.1.0_66\demos\demo.py', error 8: CreateProcess failed: Not enough storage is available to process this command."


This appears to have something to do with the thread stack size, but I’m not really sure.


I fell back to trying to compile network_timings.c (to try to test the mpich instalation) with the commands


cl network_timing.c /MD "/Ic:/program files/mpich/SDK/include" /Foa.obj

link a.obj "/LIBPATH:c:/program files/mpich/SDK/lib" mpich.lib


but this just results in the error message


C:\Documents and Settings\pou036\Desktop\shared>mpirun -localonly -np 2 a.exe

Wait for process 0 to write port to temporary file timed out


I was just wondering if you had any suggestions…





PS: as you can see I’m not really familiar with MPI on Windows and compilation issues…
