Gilles,
Applying both of your patches to the 1.8.7rc1 tarball appears to give the
desired results on both of the systems I tested.

Gilles,
If I am correctly understanding the purpose of deprecating the old
interfaces then the openib btl will *eventually* need to support
!OMPI_HAVE_CONNECTX_XRC && OMPI_HAVE_CONNECTX_XRC_DOMAINS
However, I am not in a position to decide if that is really required for
1.8.x or not.

Gilles,
I see now that your patches aren't applying because they have DOS line
endings (CRLF vs LF).
I need to strip those to get the patches applied.
I will report results with your patch on both my "old" and "new" systems as
soon as possible.

Paul,
the openib btl need to be reworked ...
currently, we have
#define HAVE_XRC (1 == OMPI_HAVE_CONNECTX_XRC)
/* and it is impossible to have !OMPI_HAVE_CONNECTX_XRC &&
OMPI_HAVE_CONNECTX_XRC_DOMAINS */
but with your patch, this becomes possible and HAVE_XRC would be zero,
which is incorrec
Paul,
i just applied the patch on the tarball, and it worked for me.
anyway, the IBV_SRQT_XRC test was misplaced (and i just read you already
found out ...)
we need if for XRC_DOMAINS and *not* for XRC
the newly attached patch will (hopefully) fix this
Cheers,
Gilles

Gilles,
I've made another observation about what I believe is an error in the XRC
configure probe.
If I am following the code below correctly, then *both* ConnectX and
ConnectIB depend on ibv_create_xrc_rcv_qp being defined.
However, that function is marked as deprecated (presumably in favor of

Gilles,
The patch didn't apply to the 1.8.7rc1 tarball.
So, I made the change manually and ran autogen.pl.
The result is that one fewer configure test runs, but "ConnectX XRC
support" is still disabled:
Diffing the configure output:
checking for ibv_resize_cq... yes
checking for struct ibv_dev
Thanks Paul,
i just found an other bug ...
(and i should be blamed for it)
here is attached a patch.
basically, xrc was incorrectly disabled on "older" ofed stacks
Cheers,
Gilles

Gilles,
A bzip2-compressed config.log is attached.
I am unsure how to determine the OFED version, because the admins have
prevented normal users from reading the RPM database.
Perhaps the following helps:
$ nm /usr/lib64/libibverbs.a | grep -i xrc
00e0 T ibv_cmd_close_xrc_domain
Paul,
can you please compress and post your config.log ?
what is the OFED version you are running ?
on master, that fix did the trick on mellanox test cluster (recent OFED
version) but did not
enable XRC on lanl test clusters (my best bet is an old OFED library)
Thanks

Preliminary report:
1) I find that "ConnectX XRC support" is still not detected as it was in
1.8.4 and earlier:
$ grep 'ConnectX XRC support' openmpi-1.*-icc-14/LOG/configure.log| sort
-u
openmpi-1.8-linux-x86_64-icc-14/LOG/configure.log:checking if ConnectX XRC
support is enabled... yes
