Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing. As the term is generally used, time slices are assigned to each process in equal portions and in circular order, handling all processes without priority. Round-robin scheduling is simple, easy to implement, and starvation-free. Round-robin scheduling can be applied to other scheduling problems, such as data packet scheduling in computer networks. It is an operating system concept.
The Andrew File System (AFS) is a distributed file system which uses a set of trusted servers to present a homogeneous, location-transparent file name space to all the client workstations. It was developed by Carnegie Mellon University as part of the Andrew Project. Originally named "Vice", "Andrew" refers to Andrew Carnegie and Andrew Mellon. Its primary use is in distributed computing.
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 software 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.
Data corruption refers to errors in computer data that occur during writing, reading, storage, transmission, or processing, which introduce unintended changes to the original data. Computer, transmission, and storage systems use a number of measures to provide end-to-end data integrity, or lack of errors.
Barbara Liskov is an American computer scientist who has made pioneering contributions to programming languages and distributed computing. Her notable work includes the introduction of abstract data types and the accompanying principle of data abstraction, along with the Liskov substitution principle, which applies these ideas to object-oriented programming, subtyping, and inheritance. Her work was recognized with the 2008 Turing Award, the highest distinction in computer science.
In computer science, a multilevel feedback queue is a scheduling algorithm. Scheduling algorithms are designed to have some process running at all times to keep the central processing unit (CPU) busy. The multilevel feedback queue extends standard algorithms with the following design requirements:
- Separate processes into multiple ready queues based on their need for the processor.
- Give preference to processes with short CPU bursts.
- Give preference to processes with high I/O bursts.
Randy Howard Katz is a distinguished professor emeritus at University of California, Berkeley of the electrical engineering and computer science department.
Jeffrey Naughton is a computer scientist and former professor and department chair of Computer Sciences at the University of Wisconsin–Madison, where he was one of the leaders of the Wisconsin Database Group. He was lead of Google's Madison office until 2022.
Input/output (I/O) scheduling is the method that computer operating systems use to decide in which order I/O operations will be submitted to storage volumes. I/O scheduling is sometimes called disk scheduling.
Gernot Heiser is a Scientia Professor and the John Lions Chair for operating systems at UNSW Sydney, where he leads the Trustworthy Systems group (TS).
Eric Allen Brewer is professor emeritus of computer science at the University of California, Berkeley and vice-president of infrastructure at Google. His research interests include operating systems and distributed computing. He is known for formulating the CAP theorem about distributed network applications in the late 1990s.
A journaling file system is a file system that keeps track of changes not yet committed to the file system's main part by recording the goal of such changes in a data structure known as a "journal", which is usually a circular log. In the event of a system crash or power failure, such file systems can be brought back online more quickly with a lower likelihood of becoming corrupted.
Thomas E. Anderson is an American computer scientist noted for his research on distributed computing, networking and operating systems.
Martin Farach-Colton is an American computer scientist, known for his work in streaming algorithms, suffix tree construction, pattern matching in compressed data, cache-oblivious algorithms, and lowest common ancestor data structures. He is the Leonard J. Shustek Professor of Computer Science and chair of the Department of Computer Science and Engineering at New York University. Formerly, he was a Distinguished Professor of Computer Science at Rutgers University. He co-founded the storage technology startup company Tokutek.
The ACM SIGOPS Mark Weiser Award is awarded to an individual who has shown creativity and innovation in operating system research. The recipients began their career no earlier than 20 years prior to nomination. The special-interest-group-level award was created in 2001 and is named after Mark Weiser, the father of ubiquitous computing.
