Hello, thanks for your help. So Open MPI is OS dependent and actually it dont support Windows plattforms.I would want to know if (Open) MPI sipports data decomposition and\ or task level parallelism. I think that MPI supports task level parallelism. But i also think that OpenMPI dont support data decomposition (like here described: http://www.netlib.org/pvm3/book/node32.html ) "out-of- the-box".
"Out-of-the-box" ? Open MPI support everything in the MPI standard, which include several functions for data decomposition. However, these functions have to be explicitly called by the application, MPI (read all MPI libraries) is unable to do any magic otherwise.
