Creating intelligent cyberinfrastructure for democratizing AI

Dhabaleswar K. Panda, Vipin Chaudhary, Eric Fosler‐Lussier, Raghu Machiraju et autres

Abstract Artificial intelligence (AI) has the potential for vast societal and economic gain; yet applications are developed in a largely ad hoc manner, lacking coherent, standardized, modular, and reusable infrastructures. The NSF‐funded Intelligent CyberInfrastructure with Computational Learning in the Environment AI Institute …

Optimizing Amber for Device-to-Device GPU Communication

Samuel Khuvis, Karen Tomko, Scott R. Brozell, Chen-Chun Chen et autres

Although direct GPU-to-GPU communication has been possible in MPI libraries for over a decade, the limited availability of compatible hardware at academic HPC centers has discouraged the development of algorithms in scientific applications that take advantage of this capability. In this paper, …
