This paper considers the problem of testing whether there exists a non‐negative solution to possibly under‐determined system linear equations with known coefficients. hypothesis arises naturally in number settings, including random coefficient, treatment effect, and discrete choice models, as well class programming problems. As first contribution, we obtain novel geometric characterization null...

This work presents LIMITLESS, a HPC framework that provides new strategies for monitoring clusters. LIMITLESS is scalable light-weight monitor integrated with other runtimes in order to obtain holistic view of the system combines both platform and application monitoring. paper description novel components architecture, including approaches reaching higher scalability based on combination in-tra...

The is built upon novel compressed sensing (CS) regularized maximum likelihood (ML) formulation discrete-input detection problem, in which l <sub ...

Abstract Battery safety is a multidisciplinary field that involves addressing challenges at the individual component level, cell as well system level. These concerns are magnified when large, high-energy battery systems for grid-scale, electric vehicle, and aviation applications. This article seeks to introduce common concepts in technical of large rechargeable systems. Lithium-ion batteries re...

Traditionally, synchronization barriers ensure that no cooperating process advances beyond a specified point until all processes have reached that point. In heterogeneous large-scale distributed computing environments, with unreliable network links and machines that may become overloaded and unresponsive, traditional barrier semantics are too strict to be effective for a range of emerging appli...

Building systems from existing applications writConsider an architecture for polylingual systems as shown in ten in two or more languages is common practice. Such systems are polylingual. Polylingual systems are relatively easy to build when the number of APIs needed to achieve language interoperability is small. However, when the number of distinct APIs become large, maintaining and evolving t...
