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

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

Another question: If MPI_Allgatherv(const void *sendbuf, int sendcount,
MPI_Datatype sendtype, void *recvbuf
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?

Hi,
Are the APIs at https://www.open-mpi.org/faq/?category=runcuda#mpi-apis-cuda
latest? I could not find MPI_Neighbor_xxx and MPI_Reduce_local.
Thanks.
