[petsc-users] PETSc-dev and OpenMP

[Danyang Su]

Hi Barry,

Thanks for following up. I just want some PETSc OpenMP example or user 
guide. Looking forward to your work on superlu_mt.

Regards,

Danyang

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?
