WebThis library revovles around Cupy tensors pinned to CPU, which can achieve 3.1x faster CPU -> GPU transfer than regular Pytorch Pinned CPU tensors can, and 410x faster GPU -> CPU transfer. Speed depends on amount of data, and number of CPU cores on your system (see the How it Works section for more details) Web1 Pinned Reply. jenkmeister. Adobe Employee, Nov 23, 2024 Nov 23, ...

Weballocator (function): CuPy pinned memory allocator. It must have the: same interface as the :func:`cupy.cuda.alloc_pinned_memory` function, which takes the buffer size as an argument and returns: the device buffer of that size. When ``None`` is specified, raw: memory allocator is used (i.e., memory pool is disabled). """ global _current_allocator WebDec 8, 2024 · The rmm::mr::device_memory_resource class is an abstract base class that defines the interface for allocating and freeing device memory in RMM. It has two key functions: 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.
