Real-Time Performance and Middleware for Multiprocessor and Multicore Linux Platforms

Free registration required

Executive Summary

An increasing number of distributed real-time applications are running on multicore platforms. However, existing real-time middleware (e.g., Real-Time CORBA) lacks adequate support for ensuring the timing constraints of soft real-time tasks on multicore platforms, and thus is dependent on (Potentially inadequate) support from the underlying operating system. This paper makes three contributions to the state of the art in real-time system software for multicore platforms.
