Abstract
At HotOS 2011, Mogul et al. published a paper calling for Reconnecting Architecture and OS Research [9]. Ten years have passed. We now live in a post-x86 world where servers are no longer homogeneous. Accelerators like GPU and FPGA are dominating important workloads like machine learning and search in data centers [3, 4]. Many data centers have launched large scales of customized ASICs (e.g., Google TPU [8], AWS Nitro [1]). At the same time, HBM and NVM are promised to change the landscape of memory and storage; various programmable networking devices like SmartNIC and programmable switches are making their ways into data centers. These exciting new hardware trends have driven systems researchers to innovate on software to fit new hardware technologies. What about the hardware?
