Improving Multicore Resource Efficiency And Performance, Syed Ali Raza Jafri

Open Access Dissertations

With clock speeds stagnating for the last few years and multi-cores having replaced uniprocessors, software development must now turn towards shared memory parallel programming to continue enhancing performance. Shared memory parallel programming; however is significantly more challenging than its sequential counterpart. Conventional shared memory parallel programs can fall victim to deadlocks, livelocks and data races which are hard to detect and debug. Aside from programming complexity chipmultiprocessors need a scalable, low latency, high bandwidth interconnect fabric to deliver performance. Conventional interconnects such as crossbars and buses can deliver low latency but do not scale with increasing number of cores. Researchers …
