Co-Designing Clusters of Lightweight Manycores and Asymmetric Operating System Kernels

Multikernel operating systems (OSs) were introduced to cope with challenges in software development and deployment in lightweight manycores. Among the possible structures for a multikernel OS, we focus on designs based on asymmetric kernels. This design delivers better performance isolation, but it suffers from an overhead in energy efficiency. In this letter, we overcome this issue with a co-desi...
