Gavin Vaz, Heinrich Riebler, Tobias Kenter and Christian Plessl received the best paper award for their paper “Deferring Accelerator Offloading Decisions to Application Runtime” at the International Conference on Reconfigurable Computing and FPGAs (ReConFig) in Cancun, Mexico.
In this paper, they have challenged the traditional HW/SW codesign approach to decide at compile time which computational expensive parts of an applications are offloaded to accelerators. The studies in the paper have shown that significant performance advantages can be gained, if the offloading decision is deferred to runtime, when more information about the properties of the hotspot are known to balance communication overheads with the expected speedup of the hotspot. An analysis of embedded and general performance workload has shown, that this method is widely applicable.
