Video: Multi-GPU FFT Performance on Different Hardware Configurations

Kevin Roe from the Maui High Performance Computing Center gave this talk at the GPU Technology Conference. “We will characterize the performance of multi-GPU systems in an effort to determine their viability for running physics-based applications using Fast Fourier Transforms (FFTs). Additionally, we’ll discuss how multi-GPU FFTs allow available memory to exceed the limits of a single GPU and how they can reduce computational time for larger problem sizes.”
