Review: Flexible System Call (Flex SC) Scheduling with Exception-Less System Calls

Abstract

FlexSC implements a “syscall” thread scheduler that is responsible for determining when and on
which core system calls will execute. While different operating systems offer a variety of different ser- vices, the basic underlying system call mechanism has been common on all commercial multi processed operating systems for decades. This scheduler is critical to performance, as it influences the locality of user and kernel execution.
