Communication scheme tests
This directory contains tests created after adding multiple communication schemes to PSBLAS.
The goal is to exercise and compare communication patterns at different layers:
- direct halo exchange (
psi_swapdata) - overlap exchange for transpose/SpMV workflows (
psi_swaptran+psi_swapdata) - full Krylov solver runs (
CG) using different comm schemes.
Communication schemes covered in this area:
psb_comm_isend_irecv_(baseline point-to-point)psb_comm_ineighbor_alltoallv_(neighbor collective)psb_comm_persistent_ineighbor_alltoallv_(persistent neighbor collective)
See:
swapdata/for a direct halo-exchange test.spmv/for an overlap SpMV test that uses different communication schemes.cg/for a conjugate-gradient solve-time comparison across the three schemes.
