Quantum field theory (QFT) simulations are a potentially important application for noisy intermediate scale quantum (NISQ) computers. The ability of a quantum…

Among the projects within the Software Technology area of the Exascale Computing Project (ECP) [1] is the SICM project [2] which focuses on delivering a…

The Best Practices for HPC Software Developers (HPC-BP) webinar series is a major component of the outreach efforts of the IDEAS Productivity Project. Since its inception, the project has been…

During the past 20 years, computation has penetrated essentially all areas of research, including science, engineering, technology, and society; advanced modeling, simulation, and data analysis…

The connection between forward backward doubly stochastic differential equations and the optimal filtering problem is established without using the Zakai's equation. The solutions of forward…

Log processing by Spark and Cassandra-based ANalytics (LogSCAN) is a newly developed analytical platform that provides flexible and scalable data gathering, transformation and computation.

Reliability, availability, and serviceability (RAS) events are recorded from almost all components in a high-performance computing (HPC) system and therefore provide useful insights into the…

The most efficient surrogate construction algorithms are carefully tailored towards the specific target model. The tailoring is commonly done on two levels, first selecting the general class of…

We present a quantum-classical algorithm to study the dynamics of the two-spatial-site Schwinger model on IBM's quantum computers. Using rotational symmetries,…

Reliability, availability and serviceability (RAS) logs of HPC resources, when closely investigated in spatial and temporal dimensions, can provide invaluable information regarding system status,…

Toolkit for Adaptive Stochastic Modeling and Non-Intrusive ApproximatioN (TASMANIAN) is an ORNL developed open source library for high dimensional integration and interpolation based…
