摘 要：In this work, I describe the MCP abstraction and the salient details of Akaros. I discuss how the kernel and user-level libraries work together to give an application control over its physical resources and to adapt to the revocation of cores at any time - even when the code is holding locks. I show an order of magnitude less interference for the MCP compared to Linux, more resilience to the loss of cores for an HPC application, and how a customized user-level scheduler can increase the performance of a simple webserver.
