Exascale Computing Project (ECP)

Highlights

With this work we looked at the overheads of in-transit and in-line visualization at various scales. We demonstrate that in-transit techniques can provide not only a time…

Scaling off-chip bandwidth is challenging due to fundamental limitations such as fixed pin count and plateauing signaling rates. Recently, vendors have turned to 2.5D and 3D stacking to closely…

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 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…

This paper describes how the OpenACC data model is implemented in current OpenACC compilers, ranging from research compilers (OpenUH and OpenARC) to a commercial compiler (the PGI…

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