Q&A

1. Because you talked about FFTW3, is there something I can do to use a distributed FFT on GPUs? I checked and there is only the intra-node hipFFTXt.

   • We can support 3^rd party libraries also if we know which ones users want.

     In one of the talks tomorrow you will see that supporting distributed libraries is not trivial for a vendor, as they need to be compiled specifically for the right MPI library, which is why it is hard to do for AMD.

   • There is work in progress from AMD but I can not say for any timeline. You can check this one: https://icl.utk.edu/fft/ but I htink I heard that the performance is not great.
