A Unified Operating System for Clouds and Manycore: Fos

Single chip processors with thousands of cores will be available in the next ten years and clouds of multicore processors afford the operating system designer thousands of cores today. Constructing operating systems for manycore and cloud systems face similar challenges. This paper identifies these shared challenges and introduces them solution: a factored operating system (fos) designed to meet the scalability, faultiness, variability of demand, and programming challenges of OS's for single-chip thousand-core manycore systems as well as current day cloud computers.
