I am using Intel Fortran v10, MPI, and Math Kernel Libraryon a cluster. I imported a scaLAPACK program that worksOK on another cluster, but fails now.A call to blacs_gridinit crashes. The call is like "call blacs_gridinit(ictxt, 'R', nprow, npcol). The nprow and npcol are defined as integer parameters = 5. When I change them to normal integer variables and set them to 5in the program,it works. Why? All the docs say they are normal input varaiables, not in and out.
Thanks for any ideas.
