Biography

I am an associate professor at the Institute of Computing Technology, Chinese Academy of Sciences since 2021 and an assistant professor from 2019 to 2021. My research focuses on big data and AI benchmarking, workload characterization, computer architecture, and proxy benchmarks for simulation. I received my Ph.D. degree in 2019 from Institute of Computing Technology, Chinese Academy of Sciences, and University of Chinese Academy of Sciences. Prof. Jianfeng Zhan is my advisor. I received my B.S. degree in 2012 from Huazhong University of Science and Technology in China.

Research

My research interests focus on the following points of Data center computing and benchmarking:
  • Big data and AI benchmarking.
  • Workload Characterization.
  • Computer Architecture.
  • Profiling and tracing in data centers.
  • Proxy benchmarks for simulation.
Undergoing projects
  • ScenarioBench: Modeling, Characterizing, and Optimizing Ultra-scale Real-world or Future Applications and Systems Using Benchmarks. We propose a scenario-distilling methodology that formalizes a real-world or future application scenario as a Directed Acyclic Graph-based model (in short, DAG model). We design and implement a reusing benchmark framework. Based on the framework, we implement the scenario benchmarks---AIBench Scenario, including E-commerce Search Intelligence and Online Translation Intelligence. AIBench Scenario is a benchmarks suite modeling AI-augmented Internet service scenarios, including E-commerce Search Intelligence and Online Translation Intelligence. Each scenario benchmark models the critical paths of a real-world application scenario as a permutation of the AI and non-AI modules.
  • AIBench Training: Balanced AI Training Benchmarks. We present a balanced methodology considering comprehensiveness, representativeness, affordability, and portability. Our methodology widely investigates AI tasks and models and covers the algorithm-level, system-level, and microarchitectural-level factors space to the most considerable extent. We provide nineteen real-world AI workloads to achieve comprehensiveness and representativeness. Besides, we propose two AIBench Training subset: RPR and WC subsets to achieve affordability. We give the hotspot functions as microbenchmarks (AIBench Micro) to achieve portability for simulator-based research after profiling.
  • AIBench Inference: Comprehensive AI Inference Benchmarks. We present a comprehensive AI inference benchmark suite including nineteen real-world AI workloads and covering text processing, image processing, audio processing, video processing, and 3D data processing.
  • HPC AI500: A Benchmark Suite for HPC AI Systems. HPC AI500 presents a comprehensive methodology, tools, Roofline performance models, and innovative metrics for benchmarking, optimizing, and ranking HPC AI systems. We abstract the HPC AI system into nine independent layers, and present explicit benchmarking rules and procedures to assure equivalence of each layer, repeatability, and replicability.
  • Data Motifs: A Lens towards Fully Understanding Big Data and AI Workloads. Identifying abstractions of time-consuming units of computation is an important step toward domain-specific hardware and software co-design. Straightforwardly, we can tailor the architecture to characteristics of an application, several applications, or even a domain of applications. Data motif is a new approach to modelling and characterizing big data and AI workloads. We consider each big data and AI workload as a pipeline of one or more classes of unit of computation performed on different initial or intermediate data inputs, each of which captures the common requirements while being reasonably divorced from individual implementations. We call this abstraction a data motif. Significantly different from the traditional kernels, a data motif’s behaviors are affected by the sizes, patterns, types, and sources of different data inputs; Moreover, it reflects not only computation patterns, memory access patterns, but also disk and network I/O patterns.
Past projects
  • BigDataBench 4.0 project. BigDataBench 4.0 adopts a scalable data motif based benchmarking methodology and contains 13 representative real-world data sets and 47 benchmarks. The latest version of BigDataBench is available from http://www.benchcouncil.org/BigDataBench/index.html.
  • Proxy Benchmark Generating for Big Data and AI. We propose a data motif-based proxy benchmark generating methodology which combines data motifs with different weights to mimic the big data and AI workloads. The proxy benchmarks shorten the execution time by 100s times on real systems while maintaining the average system and micro-architecture performance data accuracy above 90%, even changing the input data sets or cluster configurations. Moreover, the generated proxy benchmarks reflect consistent performance trends across different architectures.
  • High Throughput Computers project, Institute of Computing Technology, Chinese Academy of Sciences, Beijing. System and micro-architectural level analysis of high throughput workloads.
