Implementing consistency control mechanisms in the Clouds distributed operating system
R.C. Chen, Partha Dasgupta · 2002
Implementation of a kernel-level consistency control mechanism called invocation-based consistency control (IBCC) is presented. IBCC supports general-purpose persistent object-based distributed computing. It provides mechanisms that support a range of powerful, well-defined consistency semantics. IBCC mechanisms can also be used to implement custom recovery and synchronization. An operating-system-level implementation of IBCC as part of the Clouds distributed operating system that uses memory faulting to initiate locking and intermediate version creation is also given. Performance aspects are discussed, as well as the overhead incurred by supporting IBCC in terms of additional data structures needed in the operating system, and the additional amount of required code.>
