Petascale Cloud Computing

A recent study shows that EDGE can sustain petascale performance in the public cloud. By using a total of 27,648 c5.18xlarge cores, the solver reached a 32-bit non-zero performance of 1.09 PFLOPS when simulating seismic wave propagation. This corresponds to a hardware utilization of over 20% at an assumed stable AVX512 frequency of 2.9 GHz. Such performance was previously only possible through on-premises bare-metal supercomputing infrastructure. We will present details on high performance cloud computing at ISC High Performance 2019 with EDGE as application. Stay tuned for the date and time of the technical paper presentation. Documentation on the AWS and GCP cloud setups is available from EDGE’s user guide.

Colors denote the South-North particle velocities of eight South-North point forces after eight simulated seconds. Warm colors denote positive velocities, cold colors negative ones. The entire run covered 16 fused settings. A recent study shows that public cloud solutions can run similar settings at high performance.
