Brief Intro to My Projects at Huawei

2020/04 - now: 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.

What is Ring0

Ring0 is the most privileged protection level in CPU architectures, in which code interacts directly with physical hardware. The concept of protection ring dates back to MULTICS in 1960s. In x86 architecture, ring0 is an acronym for OS kernel and kernel mode drivers, as opposed to user mode applications in (typically) ring 3.

My blog use this domain name ring0.me to demonstrate my interest in fundamental research and technologies that build up computer systems and networks.
