Recoverable Virtual Memory through the Multi-View Memory Computer System

چکیده
Recoverable virtual memory (RVM) is very useful for applications that require fault tolerance for persistent data structures. Updates to a recoverable region of memory are recorded so that recovery in case of faults is possible. Multi-view virtual memory (MVM) provides recoverability for a memory region by defining a view, consisting of access units, on that region. Finite state machines (FSMs) control access to the units of the view. The FSM states are defined to trap on the first write to an access unit in order to save the before-image or to simply change the state of the unit so that an after-image can be recorded at a

UsulDSM: A Page-based Recoverable Distributed Shared Memory Project Report
UsulDSM is a page-based recoverable software distributed shared memory system designed for network of computers that don’t have access to a physically shared memory. In this report we describe architecture of the UsulDSM and discuss its design and implementation. We also evaluate its performance through a simple parallel application that uses UsulDSM. We also analyze UsulDSM’s scalability and t...
متن کاملSemiotics of Collective Memory of the Iran-Iraq War (Holy Defence): A Case Study of the Shared Images in Virtual Social Networks
This study aims to achieve a semiotic understanding of collective memory of the Iran-Iraq war. For this purpose, samples of images in virtual social networks shared in response to the news of discovery and return of the bodies of more than 175 divers have been analyzed. Visual signs in photographs, cartoons, graphic designs, prints, paintings and posters, in methods of historical pictures and f...
متن کاملAn experimental investigation on the energy storage in a shape-memory-polymer system
In this paper, the effect of thermomechanical loading on the behavior of deflection-based harvested energies from a shape memory polymer system is experimentally investigated. Samples are created with honeycomb cells from poly-lactic acid using additive manufacturing techniques. The shape memory effect in shape recovery and force recovery paths are studied under thermomechanical tests in bendin...
