Brief Intro to My Projects at Huawei
2020/04 - 2023/07: next-generation data center network and interconnect.
My role: one of the software architects. I designed multiple key innovations of the project.
See here for the video of a public talk by Dr. Kun Tan on APNet ‘21. [Backup link]
We are hiring exceptional people with passion for rethinking next generation data center architecture. We are one of the only teams that work closely with designers of virtually every chip in a server: from main CPU, to SmartNICs, storage and NPU (AI accelerator), which opens up a vast design space. We also have strong academic expertise and production experience in distributed systems and data center networking, which enable us to identify problems of state-of-the-art technologies, and design novel architectures to reshape the decades-old data center interconnects. Our team spreads over Beijing, Shanghai, Shenzhen, and Hangzhou.
2019/06 - 2020/04: Architect and Committer of MindSpore AKG (Auto Kernel Generator), open source.
AKG automatically compiles mathematical formulas written by kernel developers or graph optimization engine to low-level assembly of an NPU (neural processing unit). To maximize performance, AKG uses polyhedral compilation to fully automate scheduling and memory management in a complicated memory hierarchy of an NPU.
My role: architect and technical leader of dynamic shape; one of the architects of polyhedral compilation framework; one of the committers.
My technical contributions:
- Propose and implement novel solutions to non-affine access, parametric tiling, etc., which are classic open problems in polyhedral compilation;
- Refine polyhedral schedule constraints to fit NPU architecture;
- Design a combined manual and automatic schedule mechanism;
- Design the architecture and key algorithms to support dynamic shape, e.g., algebraic simplification of multivariate polynomial.
