Big data has emerged as a driving force for scientific discoveries. To meet data transfer challenges in big data era, DOE’s Advanced Scientific Computing Research (ASCR) office has funded the BigData Express project ( BigData Express is targeted at providing schedulable, predictable, and high-performance data transfer service for DOE’s large-scale science computing facilities and their collaborators. In this talk, I will present the design and architecture of BigData Express, and discuss why it meets the data transfer challenges in big data era. I will also discuss the project’s next stage research and development plan.


Dr. Wenji Wu is a Principal Network Research Investigator at Fermilab, where he has worked on high-speed networking, distributed systems and high-performance computing. His research focus is to utilize multicore and manycore to address performance challenges in high-speed networks and high-performance computing. Dr. Wu is now responsible for two DOE research projects, the MDTM project ( and the BigData Express project ( Dr. Wu earned his PhD in computer engineering from University of Arizona.
