Porting LBM simulation to GPU

You have three choices for the mini-project:

• use pure CUDA/C++ to adapt the C++ serial version from directory cpp
• use OpenACC to port the C++ serial version
• use kokkos or stdpar (for the brave) to port the C++ version to GPU
• use numba and/or CuPy to adapt the python code python/lbmFlowAroundCylinder.py
• use legate/cunumeric to adapt the python code python/lbmFlowAroundCylinder.py (dont be afraid, some feature are not yet implemented in legate/cunumeric, but it is possible to slightly refactor python to make it possible)
