Abstract :
Resource sharing unpredictably affects per-thread performance in multithreaded architectures, but system software assumes all coexecuting threads make equal progress. Per-thread cycle accounting addresses this problem by tracking per-thread progress rates for each coexecuting thread. This approach has the potential to improve Quality Of Service (QoS), Service-Level Agreements (SLA), performance predictability, service differentiation, and proportional-share performance on multithreaded architectures.
