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 ...
Torch C++ API提供了一个工具c10::optional<torch::Tensor>来指定Tensor参数为可选。有了这个,我们可以用.has_value()方法检查是否提供了输入。如果这返回true,我们就可以用.value()方法获取值。 如果.has_value()返回false,那么我们需要创建一个新的张量。ATen有很多创建张量的选项,这些选项在这里有文档(pytorch....
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 ...
%2 as the whole file name indicates standard error channel (stderr). Note: This is the default. %p in the file name string is replaced with the process ID of the application being profiled. %q{<ENV>} in the file name string is replaced with the value of the environment variable ...

It must have an atrocious effect on compilation time. You really must make it optional; and probably break it up into multiple include files. Let us decide whether we want any of that at all, or just parts of it, or none of it. ...
void* device_memory_resource::allocate(std::size_t bytes, cuda_stream_view s)—Returns a pointer to an allocation of the requested size in bytes. void device_memory_resource::deallocate(void* p, std::size_t bytes, cuda_stream_view s)—Reclaims a previous allocation of size bytes pointed...
