Hi David,
could you specify which version of OpenMPI you are using ?
I've also some parallel I/O trouble with one code but still have not
investigated.
Thanks

I have also this problem on servers I'm benching at DELL's lab with
OpenMPI-4.0.3. I've tried a new build of OpenMPI with "--with-pmi2". No
change.
Finally my work around in the slurm script was to launch my code with
mpirun. As mpirun was only finding one slot per nodes I have used
Hi OpenMPI maintainers,
I have temporary access to servers with AMD Epyc processors running RHEL7.
I'm trying to deploy OpenMPI with several setup but each time "make
check" fails on *opal_path_nfs*. This test freeze for ever consuming no
cpu resources.
After nearly one hour I have killed the

Hi all,
I've built OpenMPI 4.3.0 with GCC 9.3.0 but on the server ucx was not
available when I set --with-ucx. I remove this option and it compiles
fine without ucx. However I have a strange behavior as when using mpirun
I must explicitely remove ucx to avoid an error: in my module file I
have to

Hi Ha Chi
do you use a batch scheduler with Rocks Cluster or do you log on the
node with ssh ?
If ssh, can you check that you can ssh from one node to the other
without password ?
Ping just says the network is alive, not that you can connect.

but deeper in the code I think.

Hi,
I'm trying to solve a memory leak since my new implementation of
communications based on MPI_AllToAllW and MPI_type_Create_SubArray
calls. Arrays of SubArray types are created/destroyed at each time step
and used for communications.
On my laptop the code runs fine (running for 15000

Hi,
I'm using an old (but required by the codes) version of hdf5 (1.8.12) in
parallel mode in 2 fortran applications. It relies on MPI/IO. The
storage is NFS mounted on the nodes of a small cluster.
With OpenMPI 1.7 it runs fine but using modern OpenMPI 3.1 or 4.0.5 the
I/Os are 10x to 100x

Thanks all for your help and the workaround provided.
