PNNL-Led Co-Design Center to Enhance Graph Algorithms for Exascale Computing Project

ExaGraph: Combinatorial Methods for Enabling Exascale Applications, was selected as the fifth Exascale Computing Project Co-Design Center. The PNNL-led center will focus on graph analytics, primarily combinatorial (graph) kernels that can access computing system resources to enhance data analytic computing applications. Mahantesh Halappanavar, of ACMD Division’s Data Sciences group, will lead the new ECP center.

Setting the Standards

In a collaboration with the World Wide Web Consortium, known as W3C, PNNL data scientists Eric Stephan and Sumit Purohit were recognized for their contributions to Data on the Web Best Practices, a standards guide documenting best practices for data on the Web that recently was published as a formal Recommendation. These best practices offer data-sharing solutions for assuring scientific data have lasting impact.
