MultiK \"orchestrates\" multiple kernels that are specialized for individual applications in a transparent manner. This framework is flexible to accommodate different kernel code reduction techniques and, most importantly, run the specialized kernels with near-zero additional runtime overheads. MultiK avoids the overheads of virtualization and runs natively on the system. For instance, an Apache instance is shown to run on a kernel that has (a) 93.68% of its code red","authors_text":"Akshith Gunasekaran, David Lie, Hsuan-Chi Kuo, Jesse Walker, Rakesh B.
