LITMUSRT: AStatusReport

This paper describes a real-time extension to Linux called LITMUSRT, which is being designed to support real-time workloads on multiprocessor and multicore platforms. The recent shift by chip makers to multi- core designs, combined with building interest within the open-source community in supporting real-time features in Linux, makes this research quite timely. The devel- opment of LITMUSRT was driven by a desire to bridge the gap between those working on algorithmic issues pertaining to multiprocessor real-time resource alloca- tion and operating-systems researchers working to im- prove real-time support within operating systems such as Linux.
