To use it, make sure you have the NVIDIA CUDA Toolkit v12.8 (or later) installed, and that the NVIDIA CUPTI library is available in the toolkit (located at \texttt{CUDA\_INSTALLATION\_PATH/extras/CUPTI}). Tracing CUDA requires the creation of a Tracy CUDA context using the macro \texttt{TracyCUDAContext()}, which returns an instance of a \texttt{tracy::CUDACtx} object. TracyCUDA allows only a single \texttt{tracy::CUDACtx} object at any given time. Subsequent calls to \texttt{TracyCUDAContext()} will return the same reference-counted object. There is no need for clients to instantiate multiple \texttt{tracy::CUDACtx} objects, as a single context is capable of instrumenting all CUDA contexts and streams. diff --git a/public/tracy/TracyCUDA.hpp b/public/tracy/TracyCUDA.hpp index 132e1564..7a297146 100644 --- a/public/tracy/TracyCUDA.hpp +++ b/public/tracy/TracyCUDA.hpp @@ -19,6 +19,10 @@ using CUDACtx = std::nullptr_t; #else #include +#if CUDA_VERSION < 12080 +#error "CUDA v12.8 (or later) is required by TracyCUDA.hpp" +#endif + #include #include #include
