Scientific applications are interrupted by the operating system far too often. Historically operating systems have been written efficiently to time-share a single resource, the CPU. We now have an abundance of cores but we are still swapping out the application to run other tasks and therefore increasing the application's time to solution. Current task(More)
The advent of many-core processors is imposing many changes on the operating system. The resources that are under contention have changed; previously, CPU cycles were the resource in demand and required fair and precise sharing. Now compute cycles are plentiful, but the memory per core is decreasing. In the past, scientific applications used all the CPU(More)
