Exascale Across Scales!

Associate Professor, Computer Engineering
Rutgers University
Abstract
We discuss three different scales at which RADICAL-Cybertools are being designed and developed to support exascale computing. At the wide area distributed computing scale, we discuss the concepts and abstractions underlying the RADICAL-WLMS (Workload Management System). We demonstrate advantages to distributed workload management by integrating resource and application information on heterogeneous and dynamic resources such as OSG and XSEDE. At the application level we discuss multiple domain specific workflow systems and libraries, each of which utilizes RADICAL-Pilot middleware to support thousands (and soon tens of thousands) of concurrent and coupled simulations. At the system level we discuss how RADICAL-Pilot is being interfaced with Open Runtime Environment (ORTE) from the Open MPI Project to support the effective execution of tens of thousands of simulations.
Bio
Shantenu Jha is an Associate Professor of Computer Engineering at Rutgers University. His research interests lie at the triple point of High-performance & Distributed Computing, Computational Science and Cyberinfrastructure. Shantenu leads the the RADICAL-Cybertools project which are a suite of standards-driven and abstractions-based tools used to support large-scale science and engineering applications. He collaborates extensively with scientists from multiple domains -- including but not limited to Molecular Sciences, Earth Sciences and High-Energy Physics. He is a recipient of the NSF CAREER Award (2013) and several prizes at SC'xy and ISC'xy. He was appointed a Rutgers Chancellor's Scholar (2015-2020) and awarded a Chancellor's Excellence in Research (2016). More details can be found at http://radical.rutgers.edu/shantenu
