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`, and `sync` (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.
