Hi Junchao, both the slurm scontrol show job_id -dd and looking at
CUDA_VISIBLE_DEVICES does not provide information about which MPI process is
associated to which GPU in the node in our system. I can see this with
nvidia-smi, but if you have any other suggestion using slurm I would like to
hear it.
I've been trying to compile the code+Petsc in summit, but have been having all
sorts of issues related to spectrum-mpi, and the different compilers they
provide (I tried gcc, nvhpc, pgi, xl. Some of them don't handle Fortran 2018,
others give issues of repeated MPI definitions, etc.).
I also wanted to ask you, do you know if it is possible to compile PETSc with
the xl/16.1.1-10 suite?
Thanks!
I configured the library --with-cuda and when compiling I get a compilation
error with CUDAC:

That is a good question. Looking at
https://slurm.schedmd.com/gres.html#GPU_Management, I was wondering if you can
share the output of your job so we can search CUDA_VISIBLE_DEVICES and see how
GPUs were allocated.

Ok thanks Junchao, so is GPU 0 actually allocating memory for the 8 MPI

It says in the script it has allocated 2.4GB
Best,

Hi, Macros,
If you look at the PIDs of the nvidia-smi output, you will only find 8 unique
PIDs, which is expected since you allocated 8 MPI ranks per node.
The duplicate PIDs are usually for threads spawned by the MPI runtime (for
example, progress threads in MPI implementation). So your job script and
output are all good.
Thanks.

Hi Junchao, something I'm noting related to running with cuda enabled linear
solvers (CG+HYPRE, CG+GAMG) is that for multi cpu-multi gpu calculations, the
GPU 0 in the node is taking what seems to be all sub-matrices corresponding to
all the MPI processes in the node. This is the result of the nvidia-smi command
on a node with 8 MPI processes (each advancing the same number of unknowns in
the calculation) and 4 GPU V100s:

You can see that GPU 0 is connected to all 8 MPI Processes, each taking about
300MB on it, whereas GPUs 1,2 and 3 are working with 2 MPI Processes. I'm
wondering if this is expected or there are some changes I need to do on my
submission script/runtime parameters.
This is the script in this case (2 nodes, 8 MPI processes/node, 4 GPU/node):
