Hi Kari, Due to lack of developer resources, MPICH no longer supports the Windows platform. Please refer to our FAQ for more information: http://wiki.mpich.org/mpich/index.php/Frequently_Asked_Questions#Q:_Why_can.... We recommend you use Microsoft MPI, which can be found here: http://msdn.microsoft.com/en-us/library/bb524831(v=vs.85).aspx — Huiwei Lu Postdoc Appointee Mathematics and Computer Science Division, Argonne National Laboratory http://www.mcs.anl.gov/~huiweilu/ On Feb 26, 2014, at 2:30 AM, Karl Broich <[email protected]> wrote:

Hello,

I am trying to run dynamic process mangement using MPI4PY.

For first studies I used on Windows XP (dont laugh:-) : - MPICH 1.4.1-p 32bit - Mingw Gnu Fortran compiler with link libary libfmpich2g.a - python 2.6 with MPI4PY - test cases 1 : mandelbrot-master.py + mandelbrot-worker.f90 (I had to replace "use mpi" with "mpif.h".) - test case 2 : master.py + pi.py

I can run both testcases without errors or warnings, but the processes hang. If I interupt, the following output is given. (Note: test without dynamic process mangement work well.)

I first assumed, that there is a problem with spawning/releasing the processes from MPI4PY. But then Mr. Dalcin advised me to write a fortran master for test case 1. I did this and noticed the same behaviour. Therefore it is obviously a problem with MPICH2-installation.

Is this a known problem? If yes, is there a solution?

Thank you very much in advance. Karl
