About


Hi, I am Yuanjiang Ni. I'm currently a Ph.D. student at UC Santa Cruz. I received my Bachelor degree in Sichuan University, China in 2015. Then, I worked in the Strorage System Group, ICT for 1 year.

My research interests lie in computer systems, especially stroage systems. My previous work focus on optimizing the usage of Flash-based SSD as caches. If you want to know more more me, you can download my CV.

Projects


ONE.Efficient SSD Caching policy for Data Center Workloads(Feb. 2015 - Apr. 2016)

1.Classified 6 I/O access patterns among data-center workloads using a cost-benefit analysis

2.Proposed a novel SSD cache policy to cache data-center workloads with much weaker locality

3.Evaluated our cache policy against the state-of-the-art cache policies


TWO.Collaborative SSD cache design for high overall performance(Aug. 2014 - Jun. 2015)

1.Co-designed cache manager and flash manager to reduce write amplification

2.Implemented the cache manager in linux kernel

3.Carried out extensive evaluation to show the efficiency of our cache design
