Hi everyone,
I'm facing an issue with the typing of the performance variables I try
to register.
They are basically counters of type MCA_BASE_PVAR_CLASS_AGGREGATE,
MCA_BASE_PVAR_CLASS_COUNTER, or MCA_BASE_PVAR_CLASS_SIZE depending on
the case. In order to silence some warnings when using
op
Hi all,
when trying to run an OpenMPI + OpenMP application, using OpenMPI
v1.10.2, compiled with multi-threading support, and the OpenIB BTL, the
latter disable itself with this message:
btl:openib: MPI_THREAD_MULTIPLE not suppported; skipping this component
select: init of component openib return
Enrico,
this is fixed in Open MPI 2.1.0
fwiw, you only need MPI_THREAD_MULTIPLE if you invoke MPI subroutines
within an OpenMP parallel. if MPI is only used outside of OpenMP parallel,
then MPI_THREAD_SINGLE is very likely enough.
Cheers,
Gilles

Can you add
-mca oob_tcp_if_include eth0 ...
to your mpirun command line and see if it helps ?
if the error is still there, please follow-up in a new thread (since
this error is unlikely related to openib and multi threading)
Cheers,

Clement,
I would continue to use the SIZE_T atomics but define the PVARs type
accordingly (UNSIGNED_LONG or UNSIGNED_LONG_LONG depending on which of
their size match the one from size_t).
