About Me

I am Minhui Xie, a fourth-year Ph.D. student from Tsinghua University, advised by Professor Youyou Lu and Jiwu Shu. I am a system researcher. My research focus is building efficient systems for at-scale machine learning, with emerging hardware (e.g., persistent memory, modern GPUs). I am so excited about the interact field between ML and System.

Projects

Fleche - efficient GPU-resident embedding cache

2021-2021

  • In this work, we identify the DRAM bandwidth scarcity problem and propose Fleche to address it. Fleche’s key idea is absorbing hot accesses via a lightweight GPU-resident embedding cache.
  • Fleche gets up to 4.0x speedup of end-to-end inference throughput over NVIDIA HugeCTR, a well-known highly optimized industrial system.
  • It is published in EuroSys’22.

Kraken - memory efficient continual learning for at-scale recommendation systems

2019-2020

  • Kraken redesigns the age-old structure of embedding tables for continual learning and tailors the optimizer algorithm to make thrift use of DRAM. It can trisect the memory usage while keeping model performance.
  • It has been cited and highly rated by companies including Facebook, Tencent, Alibaba, ByteDance, Kuaishou, and Huawei. It was also incorporated into a popular open-source book on GitHub in the area of MLSys, OpenMLSys(link).
  • It is published in SC’20.
