Exploring HPC parallelism with data-driven multithreating
Christofides, Constantinos; Michael, G.; Trancoso, Pedro; Evripidou, Paraskevas (IEEE Computer Society, 2013)The switch to Multi-core systems has ended the reliance on the single processor for increase in performance and moved into Parallelism. However, the exponential growth in performance of the single processor in the 80's and ...
