Hi Gus, Ompi_info --all lists its info regarding fortran right after C. In my case: Fort real size: 4 Fort real4 size: 4 Fort real8 size: 8 Fort real16 size: 16 Fort dbl prec size: 4 Does it make any sense to you?
Hi Hugo No, dbl prec size 4 sounds weird, should be 8, I suppose, same as real8, right? It doesn't make sense, but that's what I have (now that you told me that "dbl" , not "double", is the string to search for): $ Fort dbl prec size: 4 Fort dbl cplx size: 4 Fort dbl prec align: 4 Fort dbl cplx align: 4 Is this a bug in OpenMPI perhaps? I didn't come across to this problem, most likely because the codes here don't use "double precision" but real*8 or similar. Also make sure you are picking the right ompi_info, mpif90/f77, mpiexec. Often times old versions and tangled PATH make things very confusing. Gus Correa
