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! -- Astor
