Hello,
for developing my small project, I would like to test MPI library support. I compiled OpenMPI with UCX 1.6.1. Due to limitations of my project, I need to make sure that among all ibverbs primitives UCX only uses Reliable Connections (RC). Namely, I want to make sure, that UCX does not rely on UD, DC connection types, or RDMA CM (librdmacm).
So far, I've been unsuccessful in making this setup work. I don't know what is the reason for that, but to exclude some of the option, I would be glad, if you could confirm that UCX is expected to work with RC only.
I'm trying to run the setup inside a docker container. Here is the dockerfile for creating the container. And as a Infiniband device I use SoftRoCE.
