Hi, I did an update and compiled PETSc in Frontier with gnu compilers. When
compiling my code with PETSc I see this new error pop up:
Building mpich_gnu_frontier

-cpp -DGITHASH_PP=\"FDS-6.9.1-894-g0b77ae0-FireX\"
to:
module load craype-accel-nvidia80
And then rebuild PETSc, your application
And have the same list of modules loaded at runtime.

Hi all, it seems the modules in Polaris have changed (can't find
cudatoolkit-standalone anymore).
Does anyone have recent experience compiling the library with gnu and cuda in
the machine?
Thank you!

Hi Satish,
Ok thank you for clarifying. I don't need to include Metis in the config phase
then (not using anywhere else).
Is there a way
o *.so |grep METIS_PartGraphKway
libcholmod.so:0026e500 T SuiteSparse_metis_METIS_PartGraphKway
<<<
And metis routines are already in -lcholmod [with some namespace fixes]

Hi all, I'm wondering.. Is it possible to get SuiteSparse to use Metis at
configure time with PETSc? Using Metis for reordering at symbolic factorization
phase gives lower filling for factorization matrices than AMD in some cases
(faster solution phase).

Hi all, we are trying to compile PETSc in Frontier using the structured matrix
hierarchical solver strumpack, which uses GPU and might be a good candidate for
our Poisson discretization.
The list of libs I used for PETSc in this case is:

we can see what parameters you used.
The last 100 in this row:

We are interested in doing chemistry using GPUs and already have interfaces to
PETSc from our code.

Then, check again with nvidia-smi to see if GPU memory is evenly allocated.

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

It says in the script it has allocated 2.4GB

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
