I finally managed to build openmpi in static library in visual studio (
thanks for your help), and then tried to run a program using
mpiexec -n 4 program.exe.
The answer to that was :
Cannot open configuration file
Error parsing data file mpiexec: Not found
I checked and there are *-wrapper-data.txt for the compiler wrappers ( in
the folder "share") but nothing for mpiexec. In addition, I did not
completely understand openmpi philosophy, mpic++ are supposed to be compiler
wrapper, but when are they used in the process ? and what about exact
mpiexec and mpirun roles ? I find it quite difficult to get a proper
documentation and to understand the whole picture. Could you pls direct me
to a good source of info or explain quickly how the project is structured ?
