PECS'21: The First Workshop on Performance and Energy-efficiency of Concurrent Systems
Romolo Marotta, Francesco Quaglia · 2021
Concurrent systems, based on (distributed) multi/many-core processing units, are the nowadays reference computing architecture. The (continuously-growing) level of hardware parallelism they offer has led these platforms to play a central role at any scale, ranging from data centers, to personal (mobile) devices. Optimizing performance and/or ensuring energy efficiency when running complex software stacks on top of these systems is extremely challenging due to several aspects, like data dependencies or resource sharing (and interference) among application threads, as well as VMs. Furthermore, hardware accelerators like GPGPUs or FPGAs introduce a level of heterogeneity that can potentially offer further opportunities for combined gain in performance and energy efficiency, if correctly exploited.
