Responsibilities

• Design and implement foundational collective communication operators (e.g., Send, Receive, Broadcast, Gather, Reduce, All Reduce, All Gather, etc.) tightly coupled with the NPU (Neural Processing Unit) hardware architecture.
• Optimize communication primitives to exploit hardware features like specialized communication links, on-chip interconnects, and DMA engines, minimizing latency and maximizing bandwidth.
• Analyze different communication modes (blocking / non-blocking, sync / async, reliable / unreliable) in the context of chip microarchitecture to enhance throughput and reduce stalls.
• Research and integrate communication algorithms (e.g., Ring, Hierarchical Decomposition) tailored for NPU topology and workload patterns, ensuring scalability across many compute nodes.
• Ensure software-hardware co-design compatibility, verifying correctness and performance across the chip’s instruction set, system software stack, and runtime environment.
• Perform deep debugging and profiling using hardware-level tools and logs to rapidly identify bottlenecks or correctness issues and drive resolution.
• Collaborate cross-functionally with chip architects, firmware engineers, and system software teams to deliver optimized communication solutions aligned with the overall AI accelerator roadmap.
