Features coming in V5

[ashwinstar]

Fascinating project - curious to lean the set of features and enhancements coming in Version 5 of the release
(Also, semi-curious on why bump from V3 to V5).

Trying to part self answer my question based on CHANGELOG...

* Sun Sep 17 2023 KaiGai Kohei <[email protected]> - 5.0-beta
- The code base is re-designed entirely.
- GPU code generator now generates 'kexp' pseudo code, instead of
  CUDA C++ native code. (and, run-time compile stuff by NVRTC was
  removed.)
- Now only GPU-Direct Storage is supported, and our nvme_strom.ko
  became obsolete.
- Process model was revised, unlike v3.x, 5.x series launches
  a background worker that handles all the GPU requests under
  multi-threading model. It saves device memory consumption.
- GPU-Cache is now built based on CUDA managed memory that allows
  memory overcommit.
