Research Overview
Xuehai Qian’s research focuses on parallel computer architecture, hardware/software co-designed domain-specific architectures and systems for graph analytics and machine learning, hardware security and quantum computer architecture. In parallel computer architecture area, he proposed the first scalable cache coherence protocols for atomic block execution, which can be leveraged to implement high performance sequential consistency for multiprocessors. He proposed the first hardware precise sequential consistency violation detection scheme and applied the ideas in deterministic record and replay for any relaxed memory consistency models, a well-known open problem in computer architecture community. In domain-specific architectures and systems for graph analytics, he proposed various architectures for graph processing leveraging emerging memory technology (e.g., processing-in-memory, ReRAM) to reduce and optimize data movements; he also proposed several novel distributed frameworks to optimize communication between distributed computing nodes and a specialized compiler to support advanced graph pattern mining algorithms. For machine learning, he proposed efficient synchronous and asynchronous protocols for decentralized training; with collaborators, developed several accelerator architectures with algorithm, architecture, and hardware technology co-design.
Xuehai Qian received NSF CRII and CAREER award, and led an NSF SPX project on FPGA-based machine learning platform, and other three small core NSF grants. He received the inaugural ACSIC (American Chinese Scholar In Computing) Rising Star Award. He has been induced into the “Hall of Fame” of all four top computer architecture conferences (ASPLOS, ISCA, MICRO, and HPCA). His students have been nominated for Microsoft Research Lovelace Fellowship, and Microsoft Research Ph.D Fellowship. One student was selected as Facebook Fellowship Finalist (3.5% among 2100 applicants) and awarded the Facebook Fellowship (less than 1% among all applicants). Two students were invited to attend Heidelberg Laureate Forum (HLF).
