Do benchmark for vulkan compute pipeline
We will need glslc from shaderc projec.
- For Macos, It can be installed by:
brew install shaderc - For Linux, It can be installed by:
sudo apt install glslc
Then compile and run:
cmake -S . -B build
cmake --build build
./build/vkcompbench
Note for fp64 benchmark:
- _Float64 did not get supported in clang, use double instead
Note for fp16 benchmark:
- _Float16 need gcc-12 at least
C23 features will support std::float16_t and std::float64_t, but not all current active compilers will work with new features.
- fp64: float point 64
- int64: integer 64
- fp32: float point 32
- int32: integer 32
- fp16: float point 16
- int16: integer 16
- int8: integer 8
- int8dot: integer 8 dot product
- int8dotaccsat: integer 8 dot product with accumulate and saturation
- int8dot4x8packed: integer 8 dot product with 4x8 packed
