| + | ===== Who am I ===== | ||
| + | |||
| + | I am a third-year master student under the supervision of [[binyu_zang|Prof. Binyu Zang]] and [[/haibo_chen|Dr. Haibo Chen]]. My research interests are mainly on distributed systems. I share some interesting stuff on my [[http://xoyo.name|blog]]. | ||
| + | |||
| + | ===== Education ===== | ||
| + | * M.Sci. in Software School, Fudan University, P.R.China (2009.9 ~ Now) | ||
| + | * B.Eng. in Software School, Fudan University, P.R.China (2005.9 ~ 2009.6) | ||
| + | * B.Eng. in Computer Science, University College Dublin. (Joint-degree) (2005.9 ~ 2009.6) | ||
| + | |||
| + | ===== Research Area ===== | ||
| + | |||
| + | * MapReduce and Hadoop on multicore clusters | ||
| + | * NoSQL storage and HBase | ||
| + | |||
| + | ===== Research Projects ===== | ||
| + | |||
| + | * (07/2011 ~ 10/2011) Visiting student, Rice University | ||
| + | * Project Description: Implementing ZPL programs on MapReduce and HBase cluster. ZPL is an array language for scientific computation on parallel machines. | ||
| + | * Current Status: Under implementation based on our initial design. | ||
| + | |||
| + | * (07/2010 ~ Now) Distributed NoSQL storage performance | ||
| + | * Project Description: Firstly we evaluate HBase with some real applications, and then study the HBase implementation to seek for optimization or better design. | ||
| + | * Current Status: HBase falsely sequetializes irrelative put operations and thus causes long lock acquiring time. We’re attempting to parallelize these operations. | ||
| + | |||
| + | * (03/2008 ~ Now) MapReduce performance on cluster with multi-core nodes | ||
| + | * Project Description: We studied the MapReduce performance on multi-core cluster. We tried to exploit the power of multi-core machines to maximize MapReduce efficiency. | ||
| + | * Results: The poor performance of Hadoop mainly comes from object creation, large memory footprint, naive data structure and lack of good multithreading support. We have implemented a prototype system Azwraith, which outperforms the original MapReduce implementation from 1.4X to 3.5X. | ||
| + | * Current Status: Identify the interrupt handling issues in Hadoop. Propose a federated schedule model for MapReduce. | ||
| + | |||
| + | * (09/2009 ~ 11/2009) Worked on understanding the characteristics of IO in Hadoop and surveyed applying SSD to Hadoop and HBase | ||
| + | * Results: Mixed workloads incur a random disk access pattern in Hadoop. Using SSD as a disk cache and intermediate storage would gain a good speedup. | ||
| + | |||
| + | * (03/2009 ~ 04/2009) Evaluated parallel shared-memory applications with MapReduce cluster | ||
| + | * Results: Frequent communications in this kind of applications cause significant overhead on cluster. We proposed some extensions to the MapReduce model in our APPT’09 paper. | ||
| + | |||
