Thank you for taking the time to submit an issue!

Details of the problem

There are around 40 ibm test suite failures for ompi v5.0.x with tcp path. Full test report can be found in this mtt report

There seems to be multiple issues. The following PR fixed one:

#10462

with this PR, 1sided pass.

[wzamazon]

Another PR

#10463

This fixed the segfault of pp_1sided and halo_1sided_put_alloc_mem

[wzamazon]

The hang with c_accumulate with efa turns out to be a bug in libfabric EFA installer. Fix is in ofiwg/libfabric#7829. It will take a while for mtt to ingest the change.

Remaining issue are:

1. c_put_dynamic_self/c_get_dynamic_set always hangs, even for 2 ranks.
2. When btl/tcp is used, there are segfaults with c_get_accumulate_ddt1 and c_get_accumulate_ddt2
3. When btl/tcp is used, c_accumulate is quite slow, not sure it is normal or not.

[wzamazon]

c_put_dynamic_self/c_get_dynamic_self hang will be fixed by PR #10473

[wzamazon]

Remaining issues:

With btl/ofi, mt_1sided segfault.

With btl/tcp,

1. multiple tests (1sided, c_accumulate, etc) hang.
2. c_get_accumulate_ddt1 and c_get_accumulate_ddt2 segfault.
