Scalability is the property of a system to handle a growing amount of work. One definition for software systems specifies that this may be done by adding resources to the system.
In system administration, orchestration is the automated configuring, coordinating, and managing of computer systems and software.
MapReduce is a programming model and an associated implementation for processing and generating big data sets with a parallel, distributed algorithm on a cluster.

Nimrod is a tool for the parametrization of serial programs to create and execute embarrassingly parallel programs over a computational grid. It is a co-allocating, scheduling and brokering service. Nimrod was one of the first tools to make use of heterogeneous resources in a grid for a single computation. It was also an early example of using a market economy to perform grid scheduling. This enables Nimrod to provide a guaranteed completion time despite using best-effort services.
Within cluster and parallel computing, a cluster manager is usually backend graphical user interface (GUI) or command-line interface (CLI) software that runs on a set of cluster nodes that it manages. The cluster manager works together with a cluster management agent. These agents run on each node of the cluster to manage and configure services, a set of services, or to manage and configure the complete cluster server itself In some cases the cluster manager is mostly used to dispatch work for the cluster to perform. In this last case a subset of the cluster manager can be a remote desktop application that is used not for configuration but just to send work and get back work results from a cluster. In other cases the cluster is more related to availability and load balancing than to computational or specific service clusters.
In computer science, partitioned global address space (PGAS) is a parallel programming model paradigm. PGAS is typified by communication operations involving a global memory address space abstraction that is logically partitioned, where a portion is local to each process, thread, or processing element. The novelty of PGAS is that the portions of the shared memory space may have an affinity for a particular process, thereby exploiting locality of reference in order to improve performance. A PGAS memory model is featured in various parallel programming languages and libraries, including: Coarray Fortran, Unified Parallel C, Split-C, Fortress, Chapel, X10, UPC++, Coarray C++, Global Arrays, DASH and SHMEM. The PGAS paradigm is now an integrated part of the Fortran language, as of Fortran 2008 which standardized coarrays.
Keith Marzullo is the inventor of Marzullo's algorithm, which is part of the basis of the Network Time Protocol and the Windows Time Service. On August 1, 2016 he became the Dean of the University of Maryland College of Information Studies after serving as the Director of the NITRD National Coordination Office. Prior to this he was a Professor in the Department of Computer Science and Engineering at University of California, San Diego. In 2011 he was inducted as a Fellow of the Association for Computing Machinery.
In computing, algorithmic skeletons, or parallelism patterns, are a high-level parallel programming model for parallel and distributed computing.
The International Conference on Parallel and Distributed Systems (ICPADS) is an academic conference sponsored by the IEEE Computer Society that brings together researchers and practitioners from academia and industry around the world to advance the theories, technologies, and applications of parallel and distributed systems.
Tachyon is a parallel/multiprocessor ray tracing software. It is a parallel ray tracing library for use on distributed memory parallel computers, shared memory computers, and clusters of workstations. Tachyon implements rendering features such as ambient occlusion lighting, depth-of-field focal blur, shadows, reflections, and others. It was originally developed for the Intel iPSC/860 by John Stone for his M.S. thesis at University of Missouri-Rolla. Tachyon subsequently became a more functional and complete ray tracing engine, and it is now incorporated into a number of other open source software packages such as VMD, and SageMath. Tachyon is released under a permissive license.
A distributed file system for cloud is a file system that allows many clients to have access to data and supports operations on that data. Each data file may be partitioned into several parts called chunks. Each chunk may be stored on different remote machines, facilitating the parallel execution of applications. Typically, data is stored in files in a hierarchical tree, where the nodes represent directories. There are several ways to share files in a distributed architecture: each solution must be suitable for a certain type of application, depending on how complex the application is. Meanwhile, the security of the system must be ensured. Confidentiality, availability and integrity are the main keys for a secure system.
Ümit V. Çatalyürek is a professor of computer science at the Georgia Institute of Technology, and Adjunct Professor in department of Biomedical Informatics at the Ohio State University. He is known for his work on graph analytics, parallel algorithms for scientific applications, data-intensive computing, and large scale genomic and biomedical applications. He was the director of the High Performance Computing Lab at the Ohio State University. He was named Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2016 for contributions to combinatorial scientific computing and parallel computing.
ACM SIGARCH is the Association for Computing Machinery's Special Interest Group on computer architecture, a community of computer professionals and students from academia and industry involved in research and professional practice related to computer architecture and design. The organization sponsors many prestigious international conferences in this area, including the International Symposium on Computer Architecture (ISCA), recognized as the top conference in this area since 1975. Together with IEEE Computer Society's Technical Committee on Computer Architecture (TCCA), it is one of the two main professional organizations for people working in computer architecture.
ACM SIGHPC is the Association for Computing Machinery's Special Interest Group on High Performance Computing, an international community of students, faculty, researchers, and practitioners working on research and in professional practice related to supercomputing, high-end computers, and cluster computing.

In 1989, the International Parallel and Distributed Processing Symposium established the Charles Babbage Award to be given each year to a conference participant in recognition of exceptional contributions to the field. In almost all cases, the award is given to one of the invited keynote speakers at the conference. The selection was made by the steering committee chairs, upon recommendation from the Program Chair and General Chair who have been responsible for the technical program of the conference, including inviting the speakers. It is presented immediately following the selected speaker's presentation at the conference, and he or she is given a plaque that specifies the nature of their special contribution to the field that is being recognized by IPDPS.
