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.
