Title: Ming Xia: Accelerator Link Repair and System Reliability

Introduction

Ming Xia is an inventor based in Fremont, California, and is associated with Google Inc. His patent work addresses reliability in accelerator systems, focusing on how to repair interconnect failures while preserving the availability of unaffected computing resources.

Latest Patents

Xia is named on 1 patent: “System and Method of Drainless Link Repair for Increased Accelerator Utilization During Failure.” The invention describes an accelerator architecture with multiple hosts, accelerator elements, high-speed interconnects, and a link health monitoring service. When the service detects an interconnect problem, it reports the status to a pod manager, which coordinates with a scheduler responsible for assigning processing tasks.

The pod manager identifies the least common ancestor in a binary tree that contains the elements adjacent to the failed link, then marks that ancestor and its parent nodes as unavailable. It also generates a corrective action for repairing the interconnect and communicates that action to a technician. This approach is designed to support repair while limiting disruption to accelerator utilization.

Career Highlights

The available information associates Xia with Google Inc. and identifies his patent contribution in accelerator architecture and fault management. The invention combines link monitoring, task scheduling, and targeted fault isolation to address interconnect failures in systems with multiple accelerator hosts.
