[petsc-users] PETSc-dev and OpenMP

[Barry Smith]

   Sorry I did not respond sooner. I've been trying to interface PETSc to superlu_mt for a couple of days but haven't completed it yet. I'll let you know if I get it working.

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?
