Error/segfault in basic test of CUDA-aware MPI

Specific Domains Julia at Scale
8

In the MPI.jl build.log it says:

[ Info: Using MPI library /opt/cray/pe/mpt/7.7.10/gni/mpich-gnu/8.2/lib/libmpich.so

This is in agreement with the information on the loaded cray-mpich module:

(...)
setenv		 CRAY_MPICH_DIR /opt/cray/pe/mpt/7.7.10/gni/mpich-gnu/8.2
(...)

Then doing ldd on it, I get:

There is no CUDA library linked. However, it could be that the CUDA libraries are loaded with dlopen at runtime.

What do you think?
