@jeanlucf22 can you print out some entries of xv before & right in the beginning of pdgssvx3d ?

From my eyes, this is a sparse matrix, yes, superlu can handle it. What other specialties does it have?

This is a good suggestion. Your patch has a small error: P0 (root) should also participate in MPI_Bcast(). Instead of merging your PR, I updated the macro files that generate...

Can you try the internal CBLAS/, with cmake install like: cmake .. -DTPL_ENABLE_INTERNAL_BLASLIB=ON

SuprLU_DIST does not have ILU. Sequential SuperLU has good support of ILU. Unfortunately, you cannot directly use SpTRSV, unless you put your ILU0 matrix in the SuperLU's internal L &...

Before you set any environment variable related to OpenMP, can you do this: $ echo $OMP_NUM_THREADS ? I suspect it's a large number.

Are you able to resolve the issue? It is very abnormal that when you increase OMP threads from 1 to 2, the runtime is more than doubled.

Thanks for the fix! -Sherry On Tue, May 24, 2022 at 2:48 PM liuyangzhuan ***@***.***> wrote: > Hi, > The problem is that when both superlu_dist_fortran and > superlu_dist_fortran-static are...

The default size (256MB) to use GPU memory exceeded. You can increase it to something a lot larger by setting the environment variable: export SUPERLU_MAX_BUFFER_SIZE=1024000000 This paper describes the user-tunable...
