mpptest (http://www.mcs.anl.gov/research/projects/mpi/mpptest/) has a halo exchange test. Rajeev On Nov 14, 2012, at 10:15 AM, Kokron, Daniel S. (GSFC-610.1)[Computer Sciences Corporation] wrote:
All,
I am putting together a halo-exchange benchmark that measures the impact of various strategies including Irecv/Send vs . Irecv/Isend vs use of MPI_datatypes instead of manual pack/unpack. Most importanly, I'd like to measure the impact of using the new MPI_Neighbor_alltoallw.
I have a few pieces of working code, but would love to leverage existing work in this area. I get some tantalizing hits on "simple halo exchange program". Does anyone know where I can get the code for "halocompare"
