Intro

My name is Ying Ye(叶颖), a sixth year PhD student at Computer Science department in Boston University. I got my Bachelor's Degree in Tongji University back in China. My advisor is Professor Richard West. Currently, I'm interested in performance isolation on multi-core, NUMA resource management and real-time system design. My resume can be found here

Projects

  1. Developed a memory management framework in Linux, trying to provide isolation among co-running applications accessing the shared cache via page coloring. The main problem addressed in this work is the dynamic cache partitioning mechanism, e.g. when and how re-partitioning is performed, both efficiently and effectively.

  2. Developed a real-time multicore scheduling framework in a prototype RTOS Quest. It aims at regulating resource contention for shared caches and memory bus while improving CPU utilization in a mixed criticality system. For hard real-time periodic applications, they benefit from less hardware contention and more predictable execution; for non-periodic applications, they are provided with a base level service guarantee, yet can have better performance when resource is available. A novel performance metric called average memory request latency was proposed, which outperforms the widely used memory bandwidth metric.

Miscellaneous

I'm a good climber. I spend a lot of free time on climbing at CRG (or MetroRock, sometimes outdoor). Anyone who wants to join me is welcome!
