2/23/2021 Allie Arp, CSL Last spring, several CSL students’ research was selected to be the focus of a reproducibility competition at SC20, the flagship supercomputing conference in November. The continuation of that research resulted in the students, sponsored by the IBM-Illinois Center for Cognitive Computing Systems Research (C 3SR), winning two additional awards at that same conference, for their research that will be used by governmental agencies for years to come. In addition to the Association for Computing Machinery (ACM) Special Interest Group on High Performance Certificate of Appreciation from the reproducibility competition, a paper on the research, “Petascale XCT: 3D Image Reconstruction with Hierarchical Communications on Multi-GPU Nodes,” won the SC20 Best Paper Award. The team comprises computational scientists, physicists, computer architects, computer scientists, and electrical engineers from the University of Illinois Urbana-Champaign, Argonne National Laboratory, Barcelona Supercomputing Center, and College of William & Marry. The lead author on the paper, Mert Hidayetoglu, also won first place in the ACM Graduate Student Research Competition, sponsored by Microsoft, for “Memory-Centric 3D Image Reconstruction with Hierarchical Communications on Multi-GPU Node Architecture.”
