This was my point - BLACS_PINFO has nothing to do with OMPI, so I don't know how we could help you debug it. It sounds like you have a bad blacs library. You might try ensuring it is installed correctly, you have a "good" version built from a compatible compiler, etc. > > I am using following environment: > OS: Windows 7 64-bit > Compilers: Visual Studio 2008 32bit and Intel ifort 32bit > OpenMPI: OpenMPI-1.5.3 pre-built libraries and also with > OpenMPI-1.5.2. locally built libraries > BLACS: pre-built libraries taken from > http://icl.cs.utk.edu/lapack-for-windows/scalapack/index.html#librairies > > Thank you. > -Hiral > > On Tue, Apr 19, 2011 at 6:56 PM, Ralph Castain <r...@open-mpi.org> wrote: >> Just a suggestion: have you looked at it in a debugger?
