Tariq will present his best paper at EuroPar'2020 at the virtual EuroPar'2020 conference in Warsaw, Poland.
The reverse time migration (RTM) method is critical in seismic imaging for oil and gas industries. He demonstrates the effectiveness of his Multilayer Buffer System (MLBS) framework on Shaheen-2 (using 2048 compute nodes) and Summit supercomputers (using 2048 compute nodes equipped with a total of 12288 GPUs. MLBS achieves up to 2.5X and 1.4X performance speedups compared to the reference RTM implementation for a large 3D solution grid on Shaheen-2 and Summit, respectively.
