Modeling the impact of permanent faults in caches
(2013)The traditional performance cost benefits we have enjoyed for decades from technology scaling are challenged by several critical constraints including reliability. Increases in static and dynamic variations are leading to ...

The Danger of Interval-Based Power Efficiency Metrics: When Worst Is Best
(2005)This paper shows that if the execution of a program is divided into distinct intervals, it is possible for one processor or configuration to provide the best power efficiency over every interval, and yet have worse overall ...

Modeling value speculation
(IEEE Computer Society, 2002)Several studies of speculative execution based on values have reported promising performance potential. However, virtually all microarchitectures in these studies were described in an ambiguous manner, mainly due to the ...

View Generator (VG): A mobile agent based system for the creation and maintenance of Web views
(2002)The View Generator (VG) is a system that provides the necessary components for the definition, materialization, storage, maintenance and re-use of views over remote Web-accessible databases. Through the system, clients ...

Instruction-Isomorphism in program execution
(2003)This paper identifies a fundamental runtime program property: Instruction-Isomorphism. An instruction instance is said to be isomorphic if its component - Information derived from the instruction and its backward dynamic ...

Query classification in object-oriented engineering design systems
(1994)A query model for object-oriented engineering design systems exhibits characteristics that are quite different from those found in relational models. An engineering query model should take into account the fundamental ...

Article
Two-phase commit optimizations in a commercial distributed environment
(1995)An atomic commit protocol can ensure that all participants in a distributed transaction reach consistent states, whether or not system or network failures occur. The atomic commit protocol used in industry and academia is ...

Two-phase commit optimizations and tradeoffs in the commercial environment
(Publ by IEEE, 1993)An atomic commit protocol can ensure that all participants in a distributed transaction reach consistent states, whether or not system or network failures occur. One widely used protocol is the two-phase commit (2PC) ...

Article
Two-phase commit processing with restructured commit tree
(2003)Extensive research has been carried out in search for an efficient atomic commit protocol and many optimizations have been suggested to improve the basic two-phase commit protocol, either for the normal or failure case. ...

Article
Reconciling chained and unchained transactional support for distributed systems
(1997)Distributed transactions require transaction processing support either from their communications protocols or from protocols at some higher layer. One of the earliest "industrial-strength" distributed transactional support ...

Context management and its applications to distributed transactions
(IEEE, 1996)An emerging paradigm that handles multiple locii of control in a system allows multiple program threads to work on the same task, each thread to work on a different task, or a thread to work on multiple tasks for greater ...

Personalized portals for the wireless user based on mobile agents
(2002)Wireless users rarely (if ever) benefit from Internet information services thus requiring new type of services and new ways for structuring the needed content. Personalization appears to be the most appropriate solution ...
