Dear all,

I am trying to change my MPI finite element code to OPENMP one. I am not
familiar with the usage of OPENMP in PETSc and could anyone give me some

To assemble the matrix in parallel using OpenMP pragmas, can I directly
call MATSETVALUES(ADD_VALUES) or do I need to add some locks around it?
