WebApr 15, 2014 · Unified Memory simplifies GPU memory management by providing a unified pool of memory accessible to code running on either the CPU or the GPU. ... CUDA 6 introduces XT Library interfaces which provide automatic scaling of cuBLAS level 3 and 2D/3D cuFFT routines to 2 or more GPUs. This means that if you have one or more dual … WebWhen working with multiple devices, you need to be careful with allocated memory: Allocations are tied to the device that was active when requesting the memory, and cannot be used with another device. That means you cannot allocate a CuArray, switch devices, and use that object. Similar restrictions apply to library objects, like CUFFT plans.

CUFFT_INVALID_VALUE The user specifies a … WebcuFFT provides FFT callbacks for merging pre- and/or post- processing kernels with the FFT routines so as to reduce the access to global memory. This capability is supported experimentally by CuPy. Users need to supply custom load and/or store kernels as strings, and set up a context manager via set_cufft_callbacks ().

WebJun 29, 2024 · I don’t know of any restrictions on the number of rows in a 2D CUFFT transform. Unified memory should work ok.
