Abstract
Quality-of-Service (QoS) support has become important features for various computer systems in recent years. This thesis explores real-time resource scheduling issues for QoS support starting from a central processing unit (CPU) to
redundant inexpensive/independent array disks (RAID) together in providing collaborative services. We first exploit real-time resource scheduling issues for computer systems with an advanced simultaneously multithreading (SMT) architecture, that are widely adopted in many system platforms. Specifically, we propose real-time task scheduling algorithms for SMT processors with the considerations of timing constraints and task synchronization to control the access of shared data. We then conduct a performance study on real-time request scheduling for disk-array-based I/O module disk systems to minimize the miss ratio and to improve the average response time. We consider potential data dependency among disks with an objective to minimize response time such that better system services are possible.
