Improving Per-Node Efficiency in the Datacenter with New OS
... Ideally, applications would like both high throughput and low latency. With clever kernel scheduling and a large number of cores, an operating system can provide both. The Akaros kernel scheduler achieves this by using different time quanta on separate cores, based on their workload. In traditional ...

For example, most computers don’t have an instruction to move a bit but do have one to move a byte. A less common term is word, wh ...
