Task #3077
Feature #2816: GPU offload / optimization for update&constraits, buffer ops and multi-gpu communication
Feature #2891: PME/PP GPU communications
PME/PP GPU Comms unique pointer deletion causes seg fault when CUDA calls exist in destructor
Description
When the unique pointer used for the PME-PP GPU communications objects are automatically deleted, the code sometimes seg-faults. I originally thought this was only the case when CUDA calls exist in the destructor, but have now also seen it happen even with default destructors. I have reverted to regular pointers for now. This should be investigated further, with unique pointers reinstated.
