swapdata communication test
This test was added after introducing different communication schemes in PSBLAS.
It focuses on direct halo exchange through the swapdata path:
- index list type: halo (
psb_comm_halo_) - exchange API:
psi_swapdata - phases:
start,wait, andsync(depending on test section)
Communication patterns exercised:
- baseline point-to-point (
isend/irecv) - neighbor collective (
ineighbor_alltoallv) - persistent neighbor collective (
persistent_ineighbor_alltoallv)
This test validates the low-level communication behavior in isolation, without the full SpMV overlap pipeline.
Run options
- Synthetic 3D stencil descriptor (default):
./runs/psb_comm_test [--dim N] [--iters N] [--mode both|baseline|neighbor|persistent]
- External matrix descriptor:
./runs/psb_comm_test [--iters N] [--mode both|baseline|neighbor|persistent] --matrix <path> [--fmt MM|HB]
With --matrix, the descriptor is built from the distributed input matrix pattern.
