Experience

• 2019.12 - present: Development of a parallel solver (PowerLLEL) for large-scale wall turbulence direct numerical simulations
  • Supervisor: Prof. Yun Bao & Prof. Xi Chen
  • Responsible for the design of the solver framework and numerical algorithms, as well as parallel programming
  • The solver shows excellent strong scalability to $O(10^4)$ cores on two supercomputers, namely Tianhe-2A (NSCC-GZ) and Frontera (TACC)
  • Prepare for larger-scale simulations of turbulent flows

Internship

• 2021.04 - 2021.07: Research Intern in CAE R&D Center of ZWSOFT CO., LTD.(Guangzhou)
  • Supervisor: Dr. Dongyu Liu & Mr. Yuanzhao Xu
  • Responsible for multi-core parallelization and optimization of the underlying math library of the structural solver on the x86 platform
  • Most of the optimized math functions/operations have a comparable performance to Intel MKL, accelerating the efficiency of core numerical algorithms like PCG
  • Several functions specific to finite element method are also highly optimized
