Xian-He Sun gave a keynote at the 27th IEEE International Conference on High Performance Computing and Communications (HPCC 2025) in Exeter, UK, which ran from August 13 to 15, 2025. In "From Parallel Computing to Concurrent Data Access: The Dataflow under von Neumann Machine Approach", he argued that decades of work on faster computation have made the data access problem worse.
Xian-He Sun gave the keynote at the 5th Workshop on Performance Engineering, Modeling, Analysis, and Visualization Strategy (PERMAVOST 2025), held with ACM HPDC 2025 at the University of Notre Dame on July 20, 2025. His talk, "Dataflow under the von Neumann Machine: A New Paradigm for Computing Systems", spoke directly to the workshop's focus on performance modeling.
Xian-He Sun gave the third invited talk at HPC Asia 2025 in Hsinchu, Taiwan, on February 20, 2025. The program lists it as "Dataflow under the Von Neumann machine: A Destructive New under Existing Systems". Sun argued that the memory wall, not raw compute, now limits AI systems, and presented a data-centric approach to it.
The International Open Benchmark Council (BenchCouncil) lists "CARE Cache Management" by Xiaoyang Lu and Xian-He Sun of Illinois Institute of Technology among its Chip100 Top Chip Achievements for 2022-2023 (opens in a new tab). The list was online by December 7, 2023, the date of its earliest archived copy (opens in a new tab). BenchCouncil describes the evaluation report as open for comments and subject to revision.
Xian-He Sun gave an invited keynote at the 13th CCF National Computer Architecture Conference (CCF ACA 2020) on August 13, 2020. The conference, held every two years, ran online from August 10 to 16. His talk, "Data flow under the von Neumann Computer Architecture", asked how to design a data-centric architecture for the big data era and introduced an approach he named dataflowV.
