Sorry, I spoke too soon... Reversing the order between mpi4py and petsc4py imports does work *only* on the master code side, but not on the child process code side. In that case, the program hangs after the children processes are fired up and fails the same way as reported before... cheers Rodrigo ________________________________________ From: [email protected] [[email protected]] on behalf of Rodrigo Felicio [[email protected]] Sent: Wednesday, March 01, 2017 2:31 PM To: Barry Smith Cc: [email protected] Subject: Re: [petsc-users] petsc4py and MPI.COMM_SELF.Spawn
