The objective of maintaining a high efficiency for a shared storage system often has to be compromised with the enforcement of Service-level Agreement (SLA) on quality of service (QoS). From the perspective of I/O scheduling, I/O request service order optimized for disk efficiency can be substantially different from the order required for meeting QoS requirements. When QoS takes priority, the storage...
A parallel system relies on both process scheduling and I/O scheduling for efficient use of resources, and a program's performance hinges on the resource on which it is bottlenecked. Existing process schedulers and I/O schedulers are independent. However, when the bottleneck is I/O, there is an opportunity to alleviate it via cooperation between the I/O and process schedulers: the service efficiency...
