Hello,
I have udapl over Gen2 setup on our cluster and am able to run udapl
programs. However, sometimes I get this error (after a few runs of the
same program):
open_hca: ERR ib_at_ips_by_gid for mthca0
dapls_ib_open_hca failed 40000
uDAPL uses uAT to get the IP address using the GID (ATS records via SA)
of the local device/port. The SA query for this record is failing for
some reason. Did your SM bounce during this time? Did you bounce or
reconfigure the IPoIB network device?
You can set "env DAPL_DBG_TYPE=0xffff" for more information.

I'd really appreciate if someone could help me understand what might be
going wrong.
Thanks,
Sayantan.
