Parallel Computing Hits the Power Wall

Arthur Francisco Lorenzon received his Dr. degree from Federal University of Rio Grande do Sul (UFRGS), Brazil, in 2018. Currently, he is a professor at Federal University of Pampa (UNIPAMPA), in charge of Parallel Computing, Embedded Systems, and Computer Organization disciplines at the undergraduate and graduate levels. His primary research interests include the parallelism exploitation in multicore systems, evaluation of different parallel programming interfaces, and the design of approaches to automate and optimize the thread-level parallelism exploitation. Antonio Carlos Schneider Beck Filho received his Dr. degree from UFRGS, Brazil, in 2008. Currently, he is a professor at the Applied Informatics Department at the Informatics Institute of UFRGS, in charge of Embedded Systems and Computer Organization disciplines at the undergraduate and graduate levels. His primary research interests include computer architectures and embedded systems design, focusing on power consumption.
