Re: [OMPI users] undefined reference error related to ucx
Unless you are using OSMEM I do not recommend using UCX on a Cray. You will likely get better performance with the built-in uGNI support. -Nathan > On Jun 25, 2019, at 1:51 AM, Passant A.

Re: [OMPI users] undefined reference error related to ucx
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 On 6/25/2019 5:51 PM, Passant A.

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 On Tue, Jun 25, 2019 at 5:13 PM Passant A.
