Hi Barry,
Thanks so much.
Which solvers are current OpenMP parallel currently? Can I use the
external package (e.g., SuperLU OpenMP version) with OpenMP through PETSc?
Is there any document or examples available for the usage of PETSc with
OpenMP?
Thanks again,
Danyang

You can utilize the "OpenMP version of PETSc" with your OpenMP program but
not all the solvers are OpenMP parallel currently.
Use petsc-dev and configure PETSc with ./configure --with-mpi=0
--with-openmp see http://www.mcs.anl.gov/petsc/developers/index.html

Hi All,
I have a parallel Fortran project utilizing OpenMP parallelism. Before porting
to PETSc utilizing MPICH, I want to know if it is possible to use PETSc solver
with OpenMP. There is some information for petsc-dev openmp benchmarking as can
be found here,
http://lists.mcs.anl.gov/pipermail/petsc-dev/2012-March/007817.html. If this is
possible, I would like to have a OpenMP version of PETSc solver first,
otherwise, the project will be ported to PETSc utilizing MPI. Could anybody
give me some advice on this?
Thanks and regards,
Danyang
