PROFILE

Zihang Chen

Zhenyu Chen focused on enhancing correctness and reliability in large-scale system simulations, contributing to the sarchlab/mgpusim and sarchlab/akita repositories. Working primarily in Go, Chen addressed concurrency and memory management challenges by fixing a scheduler barrier handling bug in mgpusim, which reduced false deadlock detections and improved simulation stability for barrier-intensive workloads. In akita, Chen resolved a unified memory subsystem issue by refining translation parsing during flush events and stabilizing the TLB flush path, thereby increasing memory management accuracy. These targeted bug fixes demonstrated depth in system programming and performance optimization, strengthening the robustness of both simulation platforms.
