FluidGPU C++ Runtime

This module packages the FluidGPU C++/CUDA runtime sources as a standalone static library target.

Source layout:

  • cpp_runtime/include/common.*
  • cpp_runtime/include/comm_backend.*
  • cpp_runtime/include/runtime.*
  • cpp_runtime/include/logger.h
  • cpp_runtime/include/utask.h

Build:

bash scripts/build_cpp_runtime.sh

The build requires CUDA Toolkit, CMake, a C++ compiler, libibverbs-dev, and librdmacm-dev. The nlohmann/json single header is vendored under third_party/nlohmann/ (v3.11.3, MIT-licensed) and used by default, so no extra JSON system package is needed. To force a system-installed nlohmann_json instead, pass -DFLUIDGPU_USE_SYSTEM_NLOHMANN_JSON=ON to CMake.

Missing dependencies cause the build script or CMake configure step to fail with an explicit reason.
