This talk was part of a PWL Mini supporting USENIX: https://paperswelove.org/2020/video/pwlconf-mini/ The Demikernel and the Future of Kernel-Bypass Systems Abstract: This talk presents the Demikernel, a new OS architecture for kernel-bypass I/O devices. Demikernel hides device complexity and heterogeneity by defining a new high-level, kernel-bypass I/O API and implementing it using different user-level, library OSes for each device type I will discuss the challenges in designing kernel-bypass library OSes and the future research directions in kernel-bypass for datacenter applications. Paper: http://irenezhang.net//papers/demikernel-hotos19.pdf Speaker Bio -------------------- My research focuses on datacenter operating systems and distributed systems. I completed my PhD in 2017 at the University of Washington, where I was advised by Hank Levy and Arvind Krishnamurthy. My thesis is on distributed systems for applications that span mobile devices and cloud servers. Before my PhD, I received my S.B. and M.Eng. from MIT and worked for 3 years in the virtual machine monitor group at VMware. I was born in Beijing, China but spent most of my time growing up in Columbus, Indiana. My husband and I like to cook, travel and occasionally do computer science together.
