In this paper, we explore the challenges in scaling on-chip networks towards kilo-core processors. Current low-radix topologies optimize for fast local communication, but do not scale well to kilo-core systems because of the large number of routers required. These increase both power and hop count. In contrast, symmetric high-radix topologies optimize for(More)
The exponentially growing complexity of modern processors intensifies verification challenges. Traditional pre-silicon verification covers less and less of the design space, resulting in increasing post-silicon validation effort. A critical challenge is the manual debugging of intermittent failures on prototype chips, where multiple executions of a same(More)
— Virtual CPU (VCPU) scheduling algorithms that efficiently manage processing-resource at the machine virtualization layer are key to facilitate resource sharing and workload consolidation in Clouds. Such algorithms are mostly inherited from pre-virtualization designs, thus need to be revamped and re-evaluated. This paper presents a simulation framework(More)
