Checkpointing is a technique that provides fault tolerance for computing systems. It basically consists of saving a snapshot of the application's state, so that applications can restart from that point in case of failure. This is particularly important for the long running applications that are executed in the failure-prone computing systems.
In systems engineering, dependability is a measure of a system's availability, reliability, and its maintainability, and maintenance support performance, and, in some cases, other characteristics such as durability, safety and security. In software engineering, dependability is the ability to provide services that can defensibly be trusted within a time-period. This may also encompass mechanisms designed to increase and maintain the dependability of a system or software.
David Andrew Patterson is an American computer pioneer and academic who has held the position of Professor of Computer Science at the University of California, Berkeley since 1976. He announced retirement in 2016 after serving nearly forty years, becoming a distinguished engineer at Google. He currently is Vice Chair of the Board of Directors of the RISC-V Foundation, and the Pardee Professor of Computer Science, Emeritus at UC Berkeley.
A Byzantine fault is a condition of a computer system, particularly distributed computing systems, where components may fail and there is imperfect information on whether a component has failed. The term takes its name from an allegory, the "Byzantine Generals Problem", developed to describe a situation in which, in order to avoid catastrophic failure of the system, the system's actors must agree on a concerted strategy, but some of these actors are unreliable.
Brian Randell is a British computer scientist, and Emeritus Professor at the School of Computing, Newcastle University, UK. He specialises in research into software fault tolerance and dependability, and is a noted authority on the early pre-1950 history of computers.
The International Federation for Information Processing (IFIP) is a global organisation for researchers and professionals working in the field of information and communication technologies (ICT) to conduct research, develop standards and promote information sharing.
Fault tolerance is the property that enables a system to continue operating properly in the event of the failure of some of its components. If its operating quality decreases at all, the decrease is proportional to the severity of the failure, as compared to a naively designed system, in which even a small failure can cause total breakdown. Fault tolerance is particularly sought after in high-availability or life-critical systems. The ability of maintaining functionality when portions of a system break down is referred to as graceful degradation.
The International Conference on Dependable Systems and Networks is an annual conference on topics related to dependable computer systems and reliable networks. It typically features a number of coordinated tracks, including the Dependable Computing and Communications Symposium (DCCS), the Performance and Dependability Symposium (PDS), several workshops, tutorials, a student forum, and fast abstracts. It is sponsored by the IEEE and the IFIP WG 10.4 on Dependable Computing and Fault Tolerance. DSN was formed in 2000 by merging the IEEE International Symposium on Fault-Tolerant Computing (FTCS) and the IFIP International Working Conference on Dependable Computing for Critical Applications (DCCA). The instance number for DSN is taken from FTCS which was up to its 29th instance in its last year of 1999.
The IEEE Communications Society (ComSoc) promotes the advancement of science, technology and applications in communications and related disciplines. It fosters presentation and exchange of information among its members and the technical community throughout the world. The Society maintains a high standard of professionalism and technical competency. The IEEE Communications Society is a professional society of the IEEE.
IEEE Computer Society is a professional society of the Institute of Electrical and Electronics Engineers (IEEE). Its purpose and scope is "to advance the theory, practice, and application of computer and information processing science and technology" and the "professional standing of its members." The CS is the largest of 39 technical societies organized under the IEEE Technical Activities Board.
ISO/IEC JTC 1/SC 22 Programming languages, their environments and system software interfaces is a standardization subcommittee of the Joint Technical Committee ISO/IEC JTC 1 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) that develops and facilitates standards within the fields of programming languages, their environments and system software interfaces. ISO/IEC JTC 1/SC 22 is also sometimes referred to as the "portability subcommittee". The international secretariat of ISO/IEC JTC 1/SC 22 is the American National Standards Institute (ANSI), located in the United States.
