Hello all,
I tried to use MPI_Bcast with an intercommunicator from a Fortran
program. I included mpif.h. The call got me an error message saying
that the root for the communicator was invalid and so I investigated a
little and found out that there is no MPI_ROOT in mpif.h. I found it in
mpi.h (set to -4), copied that into my Fortran program (sort of) and
voila it works now.
I dug a bit into mpif.h.in and didn't see it there either so I believe
now that this might be an oversight/bug.
Well maybe I am wrong and I misconfigured the whole thing. Here is some
of my specs.
Lam-7.1.1 recompiled for ifort-8.1 and disabled your malloc
implementation since it interferes with large memory block allocations
(different subject).
Opteron x86_64, SuSE-9.2 Linux
Hope this is enough information but a look into your codebase should
suffice to tell me whether I am full of it....
Best regards and many thanks for your help
Roland
