PROFILE

Zihang Chen

Worked on core system reliability for sarchlab/mgpusim and sarchlab/akita, focusing on concurrency and memory management in Go. Addressed scheduler barrier synchronization in mgpusim by refining barrier completion handling, which reduced false deadlock detection and improved simulation stability for barrier-heavy workloads. In akita, delivered a targeted fix to the unified memory subsystem, ensuring accurate translation parsing during flush events and refining the TLB flush path to enhance memory management reliability. Both efforts emphasized bug fixing and performance optimization, resulting in more robust system programming foundations and increased confidence in simulation and memory subsystem correctness under demanding workloads.
