COLAB: a collaborative multi-factor scheduler for asymmetric multicore processors

Teng Yu, Pavlos Petoumenos, Vladimir Janjic, Hugh Leather, John Thomson
2020 Proceedings of the 18th ACM/IEEE International Symposium on Code Generation and Optimization  
What we do not have is a scheduler that can handle all runtime factors affecting AMP for multi-threaded multi-programmed workloads.  ...  Increasingly prevalent asymmetric multicore processors (AMP) are necessary for delivering performance in the era of limited power budget and dark silicon.  ...  Acknowledgments This work was partially funded by the UK EPSRC grants Discovery: Pattern Discovery and Program Shaping for Manycore Systems (EP/P020631/1) and ABC: Adaptive Brokerage for Cloud (EP/R010528  ...

POSTER: A Collaborative Multi-Factor Scheduler for Asymmetric Multicore Processors

Teng Yu, Pavlos Petoumenos, Vladimir Janjic, Mingcan Zhu, Hugh Leather, John Thomson
2019 2019 28th International Conference on Parallel Architectures and Compilation Techniques (PACT)  
Asymmetric multicore processors (AMP) are necessary for extracting performance in an era of limited power budget and dark silicon.  ...  We have efficient symmetric schedulers, efficient asymmetric schedulers for single-threaded workloads, and efficient asymmetric schedulers for single program workloads.  ...  Among heterogeneous systems, single-ISA asymmetric multicore processors (AMPs) are becoming increasingly popular.  ...
