WebOct 29, 2024 · In trying to optimize/parallelize performing as many 1d fft’s as replicas I have, I use 1d batched cufft. I took this code as a starting point: [url] cuda - 1D batched FFTs of real arrays - Stack Overflow. To minimize the number of memory transfers I calculate the maximum batch size that will fit on my GPU based on my memory size.

WebTo control and query plan caches of a non-default device, you can index the torch.backends.cuda.cufft_plan_cache object with either a torch.device object or a device index, and access one of the above attributes. E.g., to set the capacity of the cache for device 1, one can write torch.backends.cuda.cufft_plan_cache[1].max_size = 10. WebFeb 15, 2024 · Thank you very much. I made some modification based on your code: static const char *_cufftGetErrorEnum (cufftResult error) {. switch (error) {. case CUFFT_SUCCESS: return “CUFFT_SUCCESS”; case CUFFT_INVALID_PLAN: return "The plan parameter is not a valid handle"; case CUFFT_ALLOC_FAILED: return "The …

Dear siwakorn_sukharom, I think that such combination (NVHPC + intel mkl + MPICH) should be possible. What appears to be a problem? In the makefile.include you need to provide the paths for the libraries and the compilers (see the details here ).
