Wu, Jun; Kuo, Tei-Wei; Hsueh, Chih-Wen RCPCP: A ceiling-based protocol for multiple-disk environments. (English) Zbl 1031.68016 The Computer Journal 46, No. 2, 161-173 (2003). Summary: Processes running in a multiple-disk environment may share non-preemptible resources on the processor and, at the same time, request services from disk subsystems. We propose a methodology which is efficient and easy to implement for scheduling processes in multiple-disk environments. In other words, our methodology addresses the scheduling of real-time processes which may stop to wait for disk I/O without releasing any locked semaphores. Our proposed methodology is a variation of the well-known priority ceiling protocol to schedule processes running in multiple-disk environments. The capability of the proposed methodology is verified by a series of simulation experiments under different workloads of CPU-bound and I/O-bound processes in multiple-disk environments, for which we have some encouraging experimental results.
