As multi-core processors continue to scale, more and more multiple distributed applications with precedence-constrained tasks simultaneously and widely exist in multi-functional embedded systems. Scheduling multiple DAGs-based applications on heterogeneous multi-core processors faces conflicting high-performance and real-time requirements. This study presents a multiple DAGs-based applications ...

Liu and Layland discovered the famous utilization bound N(2 1 N − 1) for fixed-priority scheduling on singleprocessor systems in the 1970’s. Since then, it has been a long standing open problem to find fixed-priority scheduling algorithms with the same bound for multiprocessor systems. In this paper, we present a partitioning-based fixed-priority multiprocessor scheduling algorithm with Liu and...

In real-time systems fixed priority scheduling techniques are considered superior than the dynamic priority counterparts from implementation perspectives; however the dynamic priority assignments dominate the fixed priority mechanism when it comes to system utilization. Considering this gap, a number of results are added to real-time system literature recently that achieve higher utilization at...

This paper investigates the usefulness of a new priority list for two-processor scheduling problem of program nets. Firstly, we discuss the weakness of a previously proposed priority list and then introduce a new priority list. Through simulation experiment we show that the new priority list is better than the previous one and can generate the same length of schedules as GA scheduling, which im...

In this paper, we investigate a simplified head-of-the-line with priority jumps (HOL-PJ) scheduling discipline. Therefore, we consider a discrete-time single-server queueing system with two priority queues of infinite capacity and with a newly introduced HOL-PJ priority scheme. We derive expressions for the probability generating function of the system contents and the packet delay. Some perfor...

This paper reviews scheduling algorithm available in RTOS to schedule the tasks during execution in the Real Time System considering the static priority and evolution in the static priority scheduling in last decade. Real Time Operating System (RTOS) success depends on completion of task in given deadline. Real Time Operating System (RTOS) used, where we require specific application that meet t...

CPU scheduling is one of the most crucial operations performed by operating systems. Different conventional algorithms like FCFS, SJF, Priority, and RR (Round Robin) are available for CPU Scheduling. The effectiveness of Priority and Round Robin scheduling algorithm completely depends on selection of priority features of processes and on the choice of time quantum. In this paper a new CPU sched...
