BIOGRAPHY
I am currently a PhD student in the Department of Electrical & Computer Engineering at the Stony Brook University. I am also a member of High Performance Data Transfer Tool Group, working with Prof. Dantong Yu and Prof. Shudong Jin. All of my past and current research projects are from the department of CSC at BNL.
I received M.S. from Xidian University in 2009, and B.S. degree in Electrical and Information Engineering from Huazhong University of Science and Technology (HUST) in 2006.
Here is my Resume.

RESEARCH
My research interest is generally in parallel processing and multicore optimizations. More specifically, I am intrigued by the problems that are related to optimize the end-system to maximize the the end-to-end performance of high-speed Ethernet/InfiniBand networks. The techniques I am usually using include multithreading, asynchronous processing, event-driven design, resource-conscious scheduling, multicore-awareness (NUMA-awareness), and kernel-bypass operations (RDMA, direct I/O, sendfile and etc). I am also interested in developing novel methodology to characterizing, modeling and pinpointing the performance bottleneck in sophisticated parallel/pipelined systems. The tools I am using here include CPU event counters (Intel VTune, OProfile, Linux perf), resource affinity (Linux numactl and libnuma utilities), and cache-coherency protocols (Intel Snoop and AMD HyperTransport). Following are the cool projects that funding my research:
Multicore-Aware Data Transfer Middleware (MDTM) . MDTM is an ongoing project of Fermilab and Brookhaven National Lab, whose goal is to design and build middleware and data transfer application to accelerate data movement at multicore systems.
See our Demo and Poster at IEEE/ACM Supercomputing 2014
FTP100. This project is to design, implement, and evaluate a ultra-high speed data transfer software, RFTP, which take advantage of RDMA and other kernel bypass techniques. I participated in the development and evaluation of RFTP software at 2010, and this project ended at 2013.

SOFTWARE
MultiCore-aware Data Transfer (Source code link) MCDT is a novel data transfer tool that adopts I/O-related resource abstraction, capacity-aware thread pools preallocation, storage-centric task mapping and thread-dependent NUMA-aware scheduler to scale up end-to-end data transfer performance over multicore systems. It is proven to be the best-performing TCP/IP-based data transfer tool for multicore servers and 40G/100G LAN/WAN Ethernet networks.
numademo with iomodel A new test module (iomodel) has been extended to linux numademo utility. It takes advantage of memory semantics to simulate I/O operations and model the I/O bandwidth performance for modern high-end NUMA systems. The resulted model can then be used to predict the I/O performance and assist the I/O related resource scheduling.
RFTP RFTP is an RDMA-based data transfer software for high performance networks, such as InfiniBand, RoCE, and iWARP. In the meantime, Linux TCP zero-copy interfaces, sendfile and splice, are also integrated into RFTP to accommodate network environments without RDMA supports. It also integrates an asynchronous I/O module for efficient disk access. The software architecture of RFTP is a combination of event-driven and multi-threaded programming model to maximize network and disk bandwidth utilization and minimize CPU utilization.
