Is compiling OpenMPI without CUDA, but with a CUDA-aware UCX a feasible approach to offer CUDA support? If not (yet), will it be at some point in the future? A clear answer on this will really help the EasyBuild community in deciding how to support building OpenMPI/UCX going forward :...
cuda: When the library is compiled with CUDA-aware support, it provides two things. First, a macro MPIX_CUDA_AWARE_SUPPORT. Secondly, the function MPIX_Query_cuda_support() that can be used to query for support. example: A non-functional extension; its only purpose is to provide an examp...
Compiling OpenMPI 1.7.2 with CUDA and Intel Compilers 13 If you are intending to compile OpenMPI with CUDA Support, do note that you have to download thefeature version of OpenMPI. The version I used for compiling OpenMPI with CUDA is version 1.7.2. The current stable version of OpenMPI 1.6...

We may want to wait for UCX 1.18.0. On our systems at JSC, we encountered issues with CUDA-aware MPI with UCX 1.17.0, either showing error messages or crashing ifUCX_TLS=[...],gdr_copyis set (which we do by default). Right now, we work around this by also settingUCX_CUDA_COPY...
