What you will work on:

As a Summer Intern on the Algorithms and Libraries Team, you will be implementing high-performance algorithms for RISC-V machines, leveraging vector processing and SiFive's custom ISA extensions. You will be invited to participate in a co-design effort with world-class architects and hardware engineers, shaping products in early development stages, and to collaborate with compiler and runtime engineers to improve compiler optimizations and integrate your algorithms into our MLIR-based parallel programming framework.

What you will learn:

  • Developing and optimizing numerical algorithms to achieve high performance on RISC-V vector machines.
  • Understanding tradeoffs between microarchitecture and algorithm designs, and the abilities and limitations of compiler optimization.
  • Analyzing software running in RTL and FPGA simulations.


  • Actively pursuing a Bachelor’s degree or higher in Computer Science, Applied Mathematics, or a related field.
  • College-level proficiency of C/C++ development in a Linux command-line environment.
  • Familiarity with parallel programming and tuning algorithms for CPU performance.
