Good afternoon, I'm getting an error message I'm not sure how to use to debug an issue. I'll try to give you all of the pertinent about the setup, but I didn't build the system nor install the software. It's an NVIDIA SuperPod system with Base Command Manager 10.0.
I'm building IOR but I'm really interested in mdtest. "module list" says I'm using the following modules: gcc/64/4.1.5a1 ucx/1.10.1 openmpi4/gcc/4.1.5 There are no problems building the code. I'm using Slurm to run mdtest using a script. The output from the script and Slurm is the following (the command to run it is included). /cm/shared/apps/openmpi4/gcc/4.1.5/bin/mpirun --mca btl '^openib' -np 1 -map-by ppr:1:node --allow-run-as-root --mca btl_openib_warn_default_gid_prefix 0 --mca btl_openib_if_exclude mlx5_0,mlx5_5,mlx5_6 --mca plm_base_verbose 0 --mca plm rsh /home/bcm/bin/bin/mdtest -i 3 -I 4 -z 3 -b 8 -u -u -d /raid/bcm/mdtest -------------------------------------------------------------------------- A requested component was not found, or was unable to be opened. This means that this component is either not installed or is unable to be used on your system (e.g., sometimes this means that shared libraries that the component requires are unable to be found/loaded). Note that Open MPI stopped checking at the first component that it did not find.
