Details
- Extended Tarang, a parallel computational fluid dynamics simulator, to enable GPU-based FFTs.
- Developed MPI and CuFFT-XT-based variable precision 1D and 3D scalable forward and inverse FFTs.
- Achieved upto 1650× single-node speed-up over FFTW on DGX-A100 and linear strong and weak scaling.
- Compared DGX-A100’s performance in PARAM Siddhi AI with EPCC Cirrus cluster with 6 V100 GPUs per node.
