Datacenters are still far away from the capability of efficiently guaranteeing user experience and quality-of-service (QoS), although there have been lots of efforts on software stack optimization. To address this challenge, in this talk, we propose a new computer architecture -- Labeled von Neumann Architecture (LvNA), which enables a new hardware/software interface by introducing a hardware labeling mechanism to convey software’s semantic information such as QoS and security to the underlying hardware. LvNA is able to correlate hardware labels with various entities (e.g., virtual machine, process and thread), propagate labels in the whole datapaths and program differentiated services rules based on labels. We will demonstrate a RISC-V based FPGA prototype (a.k.a. Labeled RISC-V) that has been already open-sourced ( We argue that LvNA is promising to be the fundamental hardware support for future datacenters.


Yungang Bao is a Professor of Institute of Computing Technology (ICT), Chinese Academy of Sciences (CAS) and the executive director of Center of Advanced Computer Systems (ACS) of ICT. His research interests include computer architecture and systems and he serves on program committees of ASPLOS, ISCA, SC and ICS etc. His research work such as Labeled von Neumann Architecture (LvNA), Hybrid Memory Trace Tool (HMTT), Partition-Based DMA Cache (absorbed and implemented in Intel's DDIO technology) and PARSEC 3.0 has been adopted by industry companies like Huawei, Intel and the research community. He was selected out to be the plenary keynote speaker at China National Computer Congress (CNCC) with 5,000 audiences in 2016. He received B.S. degree from Nanjing University in 2003 and his Ph.D. degree from ICT in 2008 and was a post-doctoral researcher of Princeton University during 2010-2012.
