It looks like v3.0 is clean - probably best to update when it is released. We know there are issues with dynamics in the 2.x series, and put a special effort to eliminate them in 3.x. > On Apr 28, 2017, at 8:48 AM, Austin Herrema wrote: > > OMPI version 2.1.0. Should have clarified that initi

[OMPI users] Closing pipes associated with repeated MPI comm spawns

2017-04-28 Thread Austin Herrema
Hello all, I am using mpi4py in an optimization code that iteratively spawns an MPI analysis code (fortran-based) via "MPI.COMM_SELF.Spawn" (I gather that this is not an ideal use for comm spawn but I don't have too many other options at this juncture). I am calling "child_comm.Disconnect()" on th
