Hi Khai,

I finally implemented LIS solver (linear algebra library, http://www.ssisc.org/lis/index.en.html) to support the OpenMP and hybrid MPI-OpenMP since the old PETSc version with OpenMP is not officially supported any more. LIS is pretty easy to be implemented if you have already implemented PETSc. You can still use PETSc DMDA to do domain decomposition but just replace the linear solver for the hybrid version.

Hi All,

I searched for the information about Petsc with OpenMP support. I came cross Danyang Su question a couple of month ago at https://lists.mcs.anl.gov/pipermail/petsc-users/2017-June/032975.htmlhttps://lists.mcs.anl.gov/pipermail/petsc-users/2017-June/032975.html . I tried to configure Petsc version 3.5.4 but it said that "Please use petsc master (git branch) for OpenMP functionality". As Barry mentioned, one has to use an older version of petsc for OpenMp support. Could you please tell me what the the last version of petsc which supports OpenMP? Thanks!
