Hi, How mxm was installed? by copying?
The rpm based installation places mxm into /opt/mellanox/mxm and not into /usr/lib64/libmxm.so. Do you use HPCx (pack of OMPI and MXM and FCA)? You can download HPCX, extract it anywhere and compile OMPI pointing to mxm location under HPCX. Also, HPCx contains rpms for mxm and fca.
