Research Status

My research has mainly focused on cloud computing, big data storage and processing in recent years, with the following results achieved:

1. For cloud computing, targeting issues with cluster such as monotonous usage mode, limited application types support, and management complexity, I put forward a new virtualization model for multiple computing resources, which can support customization and auto deployment at the levels of hardware, operating system and applications, and developed a virtual computing system accordingly. In addition, I proposed a deduplication-based virtual machine (VM) image storage and transfer method that can both reduce space consumption and boost image distribution, and presented an approach for fast live cross-datacenter VM migration.

2. For big data storage, I devised a method to combine SSD (solid state drive) and HDD (hard disk drive) to meet the requirements of big data processing and showed how to use it to accelerate MapReduce execution. Also, I studied the issues of cloud-based data storage and sharing, and co-developed MeePo, a high available cloud storage system that had been applied to China Unicom Guangdong Branch, Huawei, ZTE, CNPC, Chinese Academy of Sciences, Peking University and so on, serving more than 1.5 million registered users and 6000 enrolled communities in total, and that won the State Technological Invention Award, 2nd class in 2015.

3. For big data processing, to deal with MapReduce performance degradation on heterogeneous clusters, I put forward ActCap, a method that reduces inter-node data transfer (key cause of performance degradation) by node-capability-aware data placement; to improve MapReduce with skewed input data, I devised Skew--, a coordinated systematic solution that adopts complexity-aware keys assignment, a post-Map keys allocation scheme taking into account not only the number of keys, but also the Reduce task complexity and the key group size to balance the loads among Reducers, and other data locality and resource scheduling enhanced mechanisms to guarantee the benefit of post-Map keys allocation. ActCap can gain an average speedup of 49.8% over standard Hadoop YARN and 9.8% over Tarazu, whereas Skew-- can get an average speedup of 1.98x over standard Hadoop YARN, and 1.63x, 1.77x, and 1.41x (Reduce phase only) over SkewTune, Online Balancer, and TopCluster respectively.
