 +===== 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.
