高层工具(High-Level & Productive)包含libcu++提供 C++ 标准库扩展,如cuda::std::variant和cuda::std::optional,便于使用容器和抽象化的功能。以及Thrust提供 CPU/GPU 并行算法,用于快速开发高层算法和数据处理。 中间层工具(中等抽象层次)包含迭代器(Fancy Iterators)如cuda::std::span和cuda::std::mdspan,用于...
voidfoo(cuda::std::optional<int>); If another library,libB.so, is compiled using CCCL versionYand usesfoofromlibA.so, then this can fail if there was an ABI break between versionXandY. Unlike with API breaking changes, ABI breaks usually do not require code changes and only require recom...
void foo(cuda::std::optional<int>);If another library, libB.so, is compiled using CCCL version Y and uses foo from libA.so, then this can fail if there was an ABI break between version X and Y. Unlike with API breaking changes, ABI breaks usually do not require code changes and ...
Instead, it simply returns a std::vector<std::optional<cudaStream_t>>, which is a vector of size equal to the number of messages on the input port. Each value in the vector corresponds to the cudaStream_t specified by the message (or std::nullopt if no stream ID is found). Note ...

Specifying a stream for a kernel launch or host-device memory copy is optional; you can invoke CUDA commands without specifying a stream (or by setting the stream parameter to zero). The following two lines of code both launch a kernel on the default stream. ...
std::cout <<"GPU(s): "<< torch::cuda::device_count() << std::endl; torch::Tensor aa = tensor_image.cuda();while(1); 三个都打印出0,并且一执行tensor_image.cuda();就会奔溃。那么这种情况解决方案是:在cmakelist写 target_link_libraries(psenet c10 c10_cuda torch torch_cuda torch_cpu...
