Research

The research in Sys-Inventor Lab focuses on new strategies for next-generation computing systems, covering the OS, cloud, memory, quantum, and ML/AI technologies.

  • New Operating System design methods and principles
  • OS for Emerging Technologies and Applications
  • New Trend, AI and Quantum Computer
  • New Memory Architecture, e.g., NVM, Memory Management, Optimization, Disaggregated Memory
  • Architectural Interaction and Resource Scheduling
  • Profiling and Performance Evaluation

Projects

  1. Intelligent Operating Systems

    (1) New AI/ML-based design methods and principles for making OS intelligent. The latest thinking and efforts are in ACM TOS-2024.

    (2) ML/AI-based scheduling mechanisms on large-scale cloud servers to improve system performance, QoS, resource utilization, and save energy.

    • The study of OSML is accepted by FAST-2023.
    • The work on using ML to enhance thread scheduling on platforms with a hybird DRAM-NVM memory system is in CCF THPC-2022. Link
    • On 26/Nov 2019, the technique report about OSML is available via this Link. OSML uses multiple collaborative ML models to schedule multiple interactive resources for co-located latency-critical services.

    (3) On mobile, leveraging AI/ML technologies to optimize the system’s energy and efficiency. The latest study is in ACM TACO-2024.

  2. Quantum Computing OS and Architecture

    (1) OS for Quantum computers and computing systems

    • QuCloud (HPCA’21) and QuCloud+ (TACO’24) propose the QuOS prototypes.

    (2) Distributed quantum computing systems

    (3) The next-generation quantum computer architecture, software stack, OS, and etc.

    • QuCloud+ is in ACM TACO-2024.
    • QuCloud is in IEEE HPCA-2021 and PACT-2020.

    (4) Quantum computing simulation as well as AI.

  3. Memory Management for Large Memory Systems

    (1) iSwap - reuse pattern and learning-based memory page swap mechanism, which reduces the ineffective I/O swap operations and improves the QoS for applications with a high priority in modern OSes. iSwap works well on the latest off-the-shelf Intel/ARM platforms. The latest publication is in ACM TACO-2024.

    (2) Memory paging with fine/coarse granularities. The idea and first step effort are in ACM SIGOPS APSys-2019.

  4. Non-Volatile Memory - Hybrid Memory Management for Tiered Memory Systems in OS

    The emerging hybrid DRAM-NVM architecture is challenging the existing memory management mechanism in operating systems. In this project, we introduce Memos, which can hierarchically schedule memory resources over the entire memory hierarchy including cache, channels, main memory comprising DRAM and NVM simultaneously. Powered by our newly designed kernel-level monitoring module (HyMM) and page migration engine, Memos can dynamically optimize the data placement at the memory hierarchy in response to the on-line memory patterns, current resource utilization and memory medium features. The efforts are published in IEEE TPDS-2019 and ICCD-2016.

  5. SysMon (2014~Now)

    A light-weight OS-level system monitoring tool suite, which is able to profile the memory utilization (including cache utilization, memory footprint, approximate row-buffer locality, physical page level logic re-use time, access frequency, hot/cold features and write/read patterns) without any hardware supports. SysMon is especially useful in VM and system-level research work. Sysmon is now open source on Github. The beta version is introduced in ISCA-2014, TC-2016, and we further discuss reducing the sampling overhead in APPT-2017 in detail. In practice, it has high accuracy and low overheads.

  6. Hierarchically Optimizting Data Placement across Cache and Memory Banks on Cloud Servers (2011~Now)

    To provide ideal overall system throughput and QoS, in this project, the “Vertical Partitioning” is proposed to cooperatively optimize the data placement across cache and DRAM banks. We redesign the memory management component is OS kernel (e.g. buddy system) according to memory architecture details, thus “Vertical Partitioning” can simultaneously mitigate/eliminate the memory interferences at the entire memory hierarchy (i.e. cache-bank). Moreover, we further devise the “Curve-Vertical” Partitioning approach to handle the diverse memory behaviors exhibited by the appearing “memory-diversity” workloads on multi-core platforms. The efforts are published in ISCA-2014 and IEEE TC-2016 (Featured article invited).

    • I have led this project since 2011 (PI). This project has a continuous impact on both academia and industry. The history and development of this series of studies can be accessed via this link for Chinese version and here.
  7. Reducing Memory Conflicts on Real Cloud Servers - DRAM Bank/Channel Partitioning Mechanism (BPM/BPM+) (2011~Now)

    This work begins with the contention/interference issues in main memory systems, and I tackle them from the Operating System angle. In existing OS, memory resources are “blindly” allocated to applications (threads), leading to memory contentions in DRAM Banks in the root. In order to solve this problem, I extend the well-known Page-Coloring to eliminate/mitigate the interferences between threads on memory banks and channels. These studies help and motivate many works on improving the overall system throughput, locality and QoS. More details are in PACT-2012 and ACM TACO-2014. I have led this project since 2011 as the PI. This project has a continuous impact on both academia and industry.

    - We are glad to see Sys-Inventors’ efforts have had a long-term impact on scientific community and industry.
