A Scalability-Aware Kernel Executive for Many-Core Operating Systems

Abstract

Number, variety, and organization of the on-chip processing elements of many-core processors demand a radical rethink in operating systems design. One may come from a multitude of allocatable units that bestows every execution thread its own core: single-threaded cores will be usual, multi-threaded cores will be unusual. The paper presents a scalability-aware kernel executive, Sake, that is currently designed against such background targeting at large-scale heterogeneous manycore systems. Benchmarks on a 48-core machine motivate custom system software and special purpose systems for such modern machines.
