A digital simulation of the COVID-19 (SARS-CoV-2) spike protein that was run on the Frontera supercomputer at the Texas Advanced Computing Center (TACC) may provide needed insights for the design of potential vaccines and drugs being developed against the virus. Understanding the structure of the spike protein is crucial because the virus uses this component to infect human cells. Since this simulation provides a level of structural detail beyond that which is achievable by experiment, it promises to help researchers figure out how the virus is able to infect humans so effectively.
ORNL Announces Newest Leadership HPC: It’s More Than Just Exaflops
The Department of Energy at Oak Ridge National Laboratory (ORNL) recently announced plans for the development of a 1.5 exaflops system called Frontier to be delivered in 2021. US HPC maker Cray and chip maker AMD are the two key US commercial partners in this effort. Despite numerous press articles centered on the 1.5 exaflops peak performance of Frontier, ORNL's original RFP released in April of 2018 clearly called out the diverse workload requirements that Frontier would have to successfully handle that span the traditional modeling and simulation sector, big data analysis, and AI applications, while demonstrating a 50X improvement in solving key DOE science problems that today run at the 20 petaflops level. To meet those ambitious goals, strong support from DOE's companion $1.7 billion Exascale Computing Project (ECP) will be critical.

RIKEN Supercomputer Is Number One in the World on the Demanding HPCG Benchmark Test
Alex Larzelere, Bob Sorensen, Earl Joseph, Steve Conway and Alex Norton
At SC17 in Denver, the Japanese RIKEN K computer emerged for the third straight time as the world's most powerful supercomputer based on the High Performance Conjugate Gradient (HPCG) benchmark list. Although China's Tianhe-2 supercomputer has been widely seen as number one in the world based on its LINPAC rating, the HPCG test that the K computer excelled on may be more representative of the range of real-world HPC problems encounter by users. Riken's K computer has been either number one or two since the HPCG list came out in 2014.
