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 ...

Heterogeneous- and NUMA-aware scheduling for many-core architectures
Petrides, P.; Trancoso, Pedro (Association for Computing Machinery, Inc, 2017)As the number of cores increases in a single chip processor, several challenges arise: wire delays, contention for out-ofchip accesses, and core heterogeneity. In order to address these issues and the applications demands, ...
