Implementing consistency control mechanisms in the Cloudsdistributed operating system

摘要

Implementation of a kernel-level consistency control mechanismcalled invocation-based consistency control (IBCC) is presented. IBCCsupports general-purpose persistent object-based distributed computing.It provides mechanisms that support a range of powerful, well-definedconsistency semantics. IBCC mechanisms can also be used to implementcustom recovery and synchronization. An operating-system-levelimplementation of IBCC as part of the Clouds distributed operatingsystem that uses memory faulting to initiate locking and intermediateversion creation is also given. Performance aspects are discussed, aswell as the overhead incurred by supporting IBCC in terms of additionaldata structures needed in the operating system, and the additionalamount of required code
