Hi,
We are working on a portals4 components and we have found a bug (causing a
segmentation fault ) which must be related to the coll/basic component.
Due to a lack of time, we cannot investigate further but this seems to be
caused by a "free(disps);" (around line 300 in coll_basic_reduce_sca
Hello Emmanuel,
Which version of Open MPI are you using?

I installed intel PSM2 and then configured open mpi as follow.
./configure \
--prefix=$HOME/ompi_install \
--with-psm2=$HOME/PSM2_install/usr \
--with-psm2-libdir=$HOME/PSM2_install/usr/lib64
however, when I ran a Hello prgram, it said
mpirun -n 2 hi0
mca_base_component_reposit
How did you compile your app? Using mpicc?

Emmanuel,
I tried with both 2.x and master (they are only syntactically different
with regard to reduce_scatter) and I can't reproduce your issue. I run the
OSU test with the following command line:
mpirun -n 97 --mca coll basic,libnbc,self --mca pml ob1
./osu_reduce_scatter -m 524288: -i 1 -x 0
Hi,
this looks like the expected behavior to me.
can you try to
./configure --enable-mpirun-prefix-by-default ...
and rebuild again ?
iirc, this should add $HOME/PSM2_install/usr/lib64 to the rpath of Open
MPI, and you
will no more need to add it to your LD_LIBRARY_PATH
Cheers,
Gilles

I have no objections to this.
Unfortunately, I don't have the time to work on it, but we'd be glad to look at
pull requests to introduce this functionality. :-)

Folks,
mpirun -np 3 --oversubscribe --mca coll basic,libnbc,self --mca pml ob1
--mca btl tcp,self valgrind ./osu_reduce_scatter -m 65536:65536 -i 1 -x 0
issues some warnings such as
