Running src/measure-buf-exchange with --smpiargs="-gpu" yields CUDA Hook Library: Failed to find symbol mem_find_dreg_entries, python: undefined symbol: __PAMI_Invalidate_region

The code works for a while, and then silently exits at a later CUDA Runtime call.

Removing the --smpiargs="-gpu" option causes this to work
