The host architecture has evolved rapidly over the past decade: modern hosts have multiple heterogeneous compute devices, multiple memory devices potentially distributed across multiple cache coherence domains, and multiple network devices, all interconnected by an intra-host network. Such a host architecture alters the many fundamental assumptions that once guided the design and optimization of modern operating systems. As a result, applications running atop modern hosts suffer from suboptimal properties and performance, while host resources remain extremely underutilized.
