[petsc-users] SuperLU + GPUs

Back to SuperLU + GPUs (adding Sherry)

I get this error (appended) running 'check', as I said before. It looks
like ex19 is *failing* with CUDA but it is not clear it has anything to do
with SuperLU. I can not find these diagnostics that got printed after the
error in PETSc or SuperLU.

So this is a problem, but moving on to my code (plex/ex11 in
mark/feature-xgc-interface-rebase-v2, configure script appended). It runs.
I use superlu and GPUs, but they do not seem to be used in SuperLU:

------------------------------------------------------------------------------------------------------------------------

0.00e+00  0*

No CUDA version. The times are the same and no GPU communication above. So
SuperLU does not seem to be using GPUs.

------------------------------------------------------------------------------------------------------------------------
Event                Count      Time (sec)     Flop
     --- Global ---  --- Stage ----  Total

0.0e+00  5  0  0  0  0   5  0  0  0  0     0

There are some differences: ex19 use DMDA and I use DMPlex, 'check' is run
in my home directory, where files can not be written, and I run my code in
the project areas.

The timings are different without superlu so I think superlu is being
used.  THis is how I run this (w and w/o -mat_superlu_equil -dm_mat_type
sell)

jsrun -n 1 -a 1 -c 2 -g 1 ./ex113d_no_cuda -dim 3 -dm_view hdf5:re33d.h5

-sub_thread_block_size 4 -options_left -log_view -pc_factor_mat_solver_type
superlu -mat_superlu_equil -dm_mat_type sell

So there is a bug in ex19 on SUMMIT and I am not getting GPUs turned on in
SuperLU.
Thoughts?

Thanks,
Mark
