Cufft unified memory
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. – WebDec 30, 2015 · 2. Definitely try latest CUDA and driver. Also, if for some reason the host process associated with the program that segfaulted does not actually terminate, then you may not see the memory returned to the system pool, since the OS thinks the process is still running (it may be zombie or in some other wierd state).
