It is well known in the high-performance computing (HPC) community that many (perhaps most) HPC workloads exhibit dynamic performance envelopes that can stress the memory, compute, network, and storage capabilities of modern supercomputers. Optimizing HPC workloads to run efficiently on existing hardware systems is challenging, but attempting to quantify the performance envelopes of HPC workloads to extrapolate performance predictions for HPC workloads on new system architectures is even more challenging, albeit essential. This predictive analysis is beneficial because it helps each data center’s supercomputer procurement team extrapolate to the new machines and system architectures that will deliver the most performance for production workloads at their datacenter. However, once a supercomputer is installed, configured, made available to users, and benchmarked, it is too late to consider fundamental architectural changes.
ExaWind: How Exascale-class HPC Will Help Optimize Skyscraper-sized Wind Turbines of the Future
A wind power revolution is blowing through the U.S. electrical industry, and exascale-class supercomputing is expected to play an increasingly instrumental role in its growth. The Energy Information Administration puts wind power’s share of America’s electricity generation at 8.4 percent in 2020, up from less than 1 percent in 1990. Increasingly competitive on cost and […]

Let’s Talk Exascale: Optimizing the North American Power Grid for Reliability and Decarbonization
In this episode of Let’s Talk Exascale from the Department of Energy’s Exascale Computing Project (ECP) the focus is on an ECP application development project called ExaSGD, shorthand for Optimizing Stochastic Grid Dynamics at Exascale. The word “stochastic” means results are given in terms of probabilities instead of exact predictions — weather forecasting may be […]
