A framework to accelerate sequential programs on homogeneous multicores

This paper presents a light-weight dynamic optimization framework for homogeneous multicores. Our system profiles applications at runtime to detect hot program paths, and offloads the optimization of these paths to a Partner core. Our work contributes two insights: (1) that the dynamic optimization process is highly insensitive to runtime factors in homogeneous multicores and (2) that the Partner core´s view of application hot paths can be noisy, allowing the entire optimization process to be implemented with very little dedicated hardware in a multicore.
