Education

  • [2015-~] Indiana University-Purdue University, Indianapolis, IN

    PhD student, Computer Science.

  • [2011~2015] Huazhong University of Science & Technology, Wuhan, China

    Bachelor in Computer Science and Technology.

Research Projects

Computer Science Department at IUPUI

Jan 2019~ , Architucture-aware Neural Network

Optimize Neural Networks from the system prospective:

  • Co-locate data in deep/heterogeneous memory hierarchy, so that communication overhead between different components can be minimized.

  • Intelligent scheduling algorithm for computation kernels to enable efficient and large-scale parallelism in modern SIMD and NUMA architectures.

  • Work in progress.

Nov 2017~ Mar 2018, Memory-aware Lattice-Boltzmann Method

Prototype and optimize a memory-aware Lattice-Boltzmann Method (LBM, a computational fluid dynamics approach to simulating complex fluid flows), which can enhance data reuse across multiple time steps.

  • A paper was accepted by SBAC-PAD‘18.

April 2017~ Nov 2017, Performance Analysis of In-situ Methods in HPC

In-depth performance evaluation of various high-performance transport methods (ADIOS, flexpath, DataSpaces, Decaf, DIMEs) in multiple HPC systems.

  • A paper was accepted by HPDC‘18.

Aug 2016 ~ Mar 2017, Machine Learning Workflow in HPC

Working on s software framework for scientific workflows where RDMA technique is used to couple numerical simulation, data analysis and real-time visualization application together.

  • A distributed and optimized anomaly detection method is used to detect vortex and other special patterns from turbulence flows.

  • A paper was accepted by PEARC‘17.

Aug 2015 ~ Apr 2016, KSSR

Working on a kernelized sparse self-representation model(KSSR) and a novel Kernelized Fast Iterative Soft-Thresholding Algorithm(K-FISTA), to recover the underlying nonlinear structure among data.

  • My work mainly includes the implementation, evaluation of the KSSR model and K-FISTA algorithm.

  • A paper was accepted in SDM‘16.

Storage system group at IBM Research, Almaden

May 2018~ Aug 2018, research internship

Working on a high-performance key-value store, which uses NVMe SSD as data storage and keeps critical metadata in the persistent memory (pmem). By utilizing the advantages of persistent memory, the access to metadata such as block allocation and key-value mappings can be both hardened and fast.

May 2017~ Aug 2017, research internship

Working on persistent memory management on NVMe devices. A “collaborative paging” service is designed for extended memory mode. Paging service is lifted to userspace, to avoid expensive context switches and lengthy I/O stacks in legacy kernel designs . DPDK/SPDK tools are used to enable fast access via user space.

  • A paper is accepted in HP3C‘19.

  • My spare time

I like hiking, jogging. I have travelled to many great places in China, and I am planning to visit more places in the US! In my spare time I like playing pingpong or tennis with friends.
