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?

Thanks
Riddhi

Leo,
  Thanks for the info. That is interesting.  And yes, Having a CUDA aware MPI 
API list would be very useful.

Hi Junchao,





First, for your second question, the answer is here: 
https://www.mail-archive.com/users@lists.open-mpi.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).



Thanks.




Sincerely,
Leo

主旨: Re: [OMPI users] CUDA supported APIs

Another question: If MPI_Allgatherv(const void *sendbuf, int sendcount, 
MPI_Datatype sendtype, void *recvbuf, const int recvcounts[],const int 
displs[], MPI_Datatype recvtype, MPI_Comm comm) is cuda aware, are recvcounts, 
displs in CPU memory or GPU memory?

 latest? I could not find MPI_Neighbor_xxx and MPI_Reduce_local.
  Thanks.
