[petsc-users] Petsc with OpenMP

[Danyang Su]

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.

Regards,

Danyang
