[libfabric-users] Problems running fabtests

[Ankush Jain]

Hi all,

I'm having some trouble getting libfabric+verbs to work on my machine.

It's running Ubuntu 18.04 with Mellanox MT27710 CX-4 NICs. I am able to run
ib_send_bw with both RC and UD (and other ib_* benchmarks), and get
reasonable performance numbers.

I see both verbs and "verbs;ofi_rxm" providers if I run fi_info.
fi_pingpong also runs fine without any flags.

However if I run fi_pingpong with the flag "-p verbs", I get the
error: fi_getinfo(): util/pingpong.c:1436, ret=-61 (No data available) on
one side, and "util/pingpong.c:558 : ctrl/read: no data or remote
connection closed" on the other side.

I'm using libfabric 1.5.1, with the default mlx5_core drivers that come
with Ubuntu 18.04. I tried installing libfabric 1.7 manually and got a
different set of errors ("util/pingpong.c:1523: fi_av_insert: number of
addresses inserted = 0; number of addresses given = 1") and now I'm out of
ideas on how to get fabtests to work.

Any help would be appreciated.

Thanks,
Ankush
