Analyzing System Calls in Multi-OS Hierarchical Environments
Roberto Gioiosa, Robert W. Wisniewski, Ravi A. Murty, Todd A. Inglett · 2015
As supercomputers progress to exascale computing and beyond, the number of nodes in a supercomputer is continuing to increase, and the number of cores within a node is dramatically increasing. The amount of parallelism argues for hierarchical approaches to manage hardware resources. Currently, determining where OS functionality should be implemented in this hierarchy and how to divide functionality between the operating system and the runtime is left to the OS designer experience, without data supporting these decisions.
