Multi-core Scheduling Optimizations for Soft Real-time Multi-threaded Applications – A Cooperation Aware Approach

The use of SMP architectures to manage tasks with real-time requirements is a matter of a great amount of research today. Parallelization techniques often used for normal tasks might bring some counter effects and overall loss of predictability, which is necessary for real-time tasks. This presentation introduces the concept of task affinity in Linux kernel in order to be able to parallelize code and at the same time having better real-time responses.
