OpenMPI CUDA and CUDPP

I have mpi program to distribute the large array amongst several processes on cluster.

Each process calculates its own sum of array elements and returns the result to host.

I want to run parallel prefix scan on array elements of each process.

Any idea whether it is possible with CUDPP. ?

Has anyone used openmpi and cudpp together?

Solution

  • There's no reason why you can't combine CUDPP and MPI in the same application. They are orthogonal.

    You could also consider using Thrust's scan implementation, if you're using Fortran then see this blog post for some guidance.
