Dear PETSC users, I would like to ask a question about using an external library with MPI+OpenMP in PETSC. For example, within PETSC, I want to use MUMPS with MPI+OpenMP. This means that if one node has 12 MPI processes and 24GB, MUMPS uses 4 MPI processes with 6GB and each MPI process has 3 threads. To do this, what should be done from PETSC installation? After using MUMPS in this way, is there a way to convert from MPI+OpenMP to flat MPI? Thank you!
Regards, Evan
