Hello I was able to correctly install and test OpenMPI 4.0.1 functionality on my Mac. However, I am running into another problem. I am running an astrophysical code named PLUTO which uses certain old routines which have been discontinued in the newer MPI versions. As a result, I face errors during the ‘make’ process. The error log is attached as a text file. Can someone guide me as to how I can fix that and make use of new routines?

That is interesting. And yes, Having a CUDA aware MPI API list would be very useful. --Junchao Zhang On Mon, Aug 19, 2019 at 10:23 AM Fang, Leo <leof...@bnl.gov<mailto:leof...@bnl.gov>> wrote: Hi Junchao, First, for your second question, the answer is here: https://firstname.lastname@example.org/msg33279.html. I know this because I also asked it earlier 😊 It'd be nice to have this documented in the Q&A though. As for your first question, I am also interested. It'd be nice for Open MPI core devs to keep the supported API list up-to-date. We recently added support of CUDA-aware MPI to mpi4py, and such a list is important for us to keep track upstream support so that we know whether a test fails due to lack of CUDA-awareness or because we messed up (much less likely).
