Passant,
The support for UCX 1.6 has been backported into the v4.0.x branch, but
after Open MPI 4.0.1 was released,
and it will be available in Open MPI 4.0.2.
Meanwhile, you can manually download and apply the patch at
https://patch-diff.githubusercontent.com/raw/open-mpi/ompi/pull/6748.patch
Cheers,
Gilles

Thanks Gilles!
The thing is I'm having this error
ud_iface.c:271 UCX Assertion `qp_init_attr.cap.max_inline_data >=
UCT_UD_MIN_INLINE' failed
and core files.
I looked that up and it was suggested here
https://github.com/openucx/ucx/issues/3336 that the UCX 1.6 might solve this
issue, so I tried the pre-release version to just check if it will.
All the best,

Passant,
UCX 1.6.0 is not yet officially released, and it seems Open MPI
(4.0.1) does not support it yet, and some porting is needed.
Cheers,
Gilles

Hello,
I'm trying to build ompi 4.0.1 with external ucx 1.6.0 but I'm getting
../../../opal/.libs/libopen-pal.so: undefined reference to
`uct_ep_create_connected'
collect2: error: ld returned 1 exit status
configure line for ompi
./configure --prefix=/opt/ompi401_ucx16 --with-slurm --with-hwloc=internal

--with-ucx=/opt/ucx-1.6.0
configure line for ucx
./configure --prefix=/opt/ucx-1.6.0
What could be the reason?
All the best,
