Ok, I got more issues. Maybe someone on the list can help me:
Open MPI version: 4.1.1 download from github source
Compile on Centos 8.4 using GCC 8.4.1
Configured is:
./configure --enable-shared --enable-static \
--without-tm \
--enable-mpi-cxx \
--enable-wrapper-runpath \
--enable-mpirun-prefix-by-default \
--enable-mpi-thread-multiple \
--enable-mpi-fortran=yes \
--prefix=/p/app/compilers/mpi/openmpi/4.1.1 2>&1 \
| tee config.log
Intel HPC system, 850 nodes trying to launch IOR benchmark.
Top portion of the mpi command:
-------------------------------------------------------------------------------------
export OMPI_MCA_btl_openib_allow_ib=1
export OMPI_MCA_btl_openib_if_include="mlx5_0:1"
mpirun -machinefile ${hostlist} \
--mca opal_common_ucx_opal_mem_hooks 1 \
\
-np ${NP} \
--map-by node \
-N ${rpn} \
-vv \
---------------------------------------------------------------------------------------------------------
I am getting the message <node name:pid> [##] mca_sharedfp_lockedfile_file_open
: Error during file open
on all the nodes.
I've tried it with the --mca sharedfp lockedfile and without, I still get the
errors.
What Have I done wrong ?
Thanks ..
