CuPy is an open-source matrix library accelerated with NVIDIA CUDA. It also uses CUDA-related libraries including cuBLAS, cuDNN, cuRand, cuSolver, cuSPARSE, cuFFT, and NCCL to make full use of the GPU architecture. It is an implementation of a NumPy-compatible multi-dimensional array on CUDA.

The run time for numpy was: 0.032. While the run time for cupy was: 0.484. To clarify from the answers, the ONLY work this code does on the GPU is create the random integers. Everything else is on the CPU with many small operations to just copy data from ...
WebTLDR: PyTorch GPU fastest and is 4.5 times faster than TensorFlow GPU and CuPy, and the PyTorch CPU version outperforms every other CPU implementation by at least 57 times (including PyFFTW). My best guess on why the PyTorch cpu solution is better is that it possibly better at taking advantage of the multi-core CPU system the code ran on. In [1 ... WebBecause GPU executions run asynchronously with respect to CPU executions, a common pitfall in GPU programming is to mistakenly measure the elapsed time using CPU timing utilities (such as time.perf_counter () from the Python Standard Library or the %timeit magic from IPython), which have no knowledge in the GPU runtime. cupyx.profiler.benchmark …
