WebNov 30, 2024 · Apple. Apple is rethinking how components should exist and operate inside a laptop. With M1 chips in new Macs, Apple has a new “Unified Memory Architecture” (UMA) that dramatically speeds up memory performance. Here’s how memory works on Apple Silicon. 0 seconds of 1 minute, 13 secondsVolume 0%. 00:25. WebMar 17, 2024 · The data copy is done using cuFFT's API, so please refer to the multi-GPU example in cuFFT documentation linked in my post. What's done in CuPy's low-level API is an almost 1-to-1 translation of that. It is interesting to explore if managed (unified) memory can be of any help, but I didn't pay much attention during development. –
