Real-Time Scheduling for Parallel Task Models on Multi-core Processors - A critical review

Multi-core processor technology has been enhanced spectacularly and it is reasonably good in performance than single core processors thereby having the potential to enable computationintensive real-time applications with precise timing constraints. Mostly traditional multiprocessor real - time scheduling is stick to Sequential models which ignore intra-task parallelism while Parallel models such as OpenMP have the capability to parallelize specific segments of tasks, thereby leading to shorter response times when possible. In this paper various research papers have been reviewed and are categorized as Sequential Real-Time Task based Research and Parallel Real-Time Task based Research. Also various approaches such as task splitting techniques, scheduling policies and techniques used are considered for comparing real time task scheduling in multi-core processors.
