Dear Jeff, Dear all,
I normaly use "USE MPI"
This is the answar fro intel HPC forum:
*If you are switching between intel and openmpi you must remember not to
mix environment. You might use modules to manage this. As the data types
encodings differ, you must take care that all objects are built
When you change environment, that is change between OpenMPI and Intel MPI,
or compiler, it is recommended that you recompile everything.
use mpi
is a module, you cannot mix these between compilers/environments, sadly the
Fortran specification does not enforce a strict module format which is why

Lev:
Can you run with --mca mpi_common_cuda_verbose 100 --mca mpool_rgpusm_verbose
100 and send me (rvandeva...@nvidia.com) the output of that.
Thanks,

Diego,
basically that means "do not build with openmpi and run with intelmpi, or
the other way around" and/or "do not build a part of your app with openmpi
and an other part with intelmpi"
"part" can be your app or the use of third party libraries.
if you use intel scalapack, make you use the lib
Dear Nick, Dear all,
I use mpi.
I recompile everything, every time.
I do not understand what I shall do.
Thanks again

You still havent shown us anything about what goes wrong, you just give us
the error statement and assume it is because of ill-defined type-creation,
it might as well be because you call allreduce erroneously.
Please give us more information...

Diego,
did you update your code to check all MPI calls are successful ?
(e.g. test ierr is MPI_SUCCES after each MPI call)
can you write a short program that reproduce the same issue ?
if not, is your program and input data public ally available ?
Cheers,
Gilles

Hi Diego,
I think the Intel HPC forum comment is about using environment modules to
manage your environment (PATH, LD_LIBRARY_PATH variables).
Most HPC systems use environment modules:
- Tcl ( http://modules.cvs.sourceforge.net/viewvc/modules/modules/tcl/ )
- C/Tcl ( http://sourceforge.net/proje
Dear all, Dear Nick,
you are right.
now will try to erase every time all *.mod file and *.o file. After thar
recompile all *.f90 files.
If I get another error I will tell you also the message.
Thanks again
Diego

There is also the package Lmod, which provides similar functionality
to environment modules. It is maintained by TACC.

but I think the current source code is at
