COMPUTING APPARATUS HAVING MULTI-LEVEL SCHEDULER BASED ON MULTI-CORE AND SCHEDULING METHOD THEREOF

摘要

PURPOSE: A multicore-based computing device and a hierarchical scheduling method thereof are provided to reduce unnecessary cache use and optimize a scheduling process for a multicore system. CONSTITUTION: A computing device (100) has a multicore system with a hierarchical structure (a first hierarchy, a second hierarchy). The first hierarchy includes a physical platform (102) and a virtual machine monitor (103) which runs on the physical platform. The second hierarchy includes virtual platforms (104a, 104b) controlled by the virtual machine monitor (103) and operation systems (105a, 105b) which run on the virtual platforms. A virtual platform includes multiple virtual cores (106a, 106b, 106c, 106d, 106e).
