[petsc-users] MPI+OpenMP+MKL

Hello petsc-users,
I am trying to use a code that is parallelized with a combination of OpenMP
and MKL parallelisms, where OpenMP threads are able to spawn MPI processes.
I have carefully scheduled the processes such that the right amount is
launched, at the right time.
When trying to use my code inside a MatShell (for later use in an FGMRES
KSPSolver), MKL processes are not being used.
I am sorry if this has been asked before.
What configuration should I use in order to profit from MPI+OpenMP+MKL
parallelism?
Thank you!
