Whitepaper: Asymmetric Scheduling and Load Balancing for Real-Time on Linux SMP

by Universite des Sciences et Technologies de LilleJan 01, 2008

This paper proposes ARTiS, a scheduler based on a partition of the multiprocessor CPUs into RT processors where tasks are protected from jitter on the expected latencies and NRT processors where all the code that may lead to a jitter is executed. This partition does not exclude a load-balancing of the tasks on the whole machine, it only implies that some tasks are automatically migrated when they are about to become non-preemptible. An implementation of ARTiS was evaluated on a 4-way IA-64 and a
