Hey,

Try setting export FI_LOG_LEVEL={warn/info/debug}

Best,
Seth

Hi all!


I've got an error from IntelMPI saying that fi_getinfo() has failed.


MPIR_Init_thread(189)........:
MPID_Init(1561)..............:
MPIDI_OFI_mpi_init_hook(1584):
open_fabric(2663)............:
find_provider(2823)..........: OFI fi_getinfo() failure


Looking at source code of fi_getinfo I see that there are some debug
logs possible which may explain the reason to me,
e.g. there is a line FI_WARN(&core_prov, FI_LOG_CORE, "fi_getinfo:
provider %s output empty list\n", prov->provider->name);
and there are also some lines with FI_DBG(...)
see: https://github.com/ofiwg/libfabric/blob/main/src/fabric.c#L1231 <https://github.com/ofiwg/libfabric/blob/main/src/fabric.c#L1231>


How to enable logging in order to see these logs somewhere? Where do
they appear (log file, stdout?)


Is there any better way to resolve why fi_getinfo() has failed?


Regards,


Łukasz
