DRMAA
Distributed Resource Management Application API (DRMAA) is a high-level Open Grid Forum (OGF) API specification for the submission and control of jobs to a distributed resource management (DRM) system, such as a cluster or grid computing infrastructure. The scope of the API covers all the high level functionality required for applications to submit, control, and monitor jobs on execution resources in the DRM system. In 2007, DRMAA was one of the first two (the other one was GridRPC) specifications that reached the full recommendation status in the OGF. In 2012 the second version of the DRMAA standard (DRMAA2) was published in an abstract interface definition language (IDL) defining the semantic of the functions in GFD 194. DRMAA2 specifies more than twice as many calls as DRMAA. It covers cluster monitoring, has a notion of queues and machines, and introduces a multi job-session concept for single applications for a better job workflow management. Later in 2012 the C API was specif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Grid Forum
The Open Grid Forum (OGF) is a community of users, developers, and vendors for standardization of grid computing. It was formed in 2006 in a merger of the Global Grid Forum and the Enterprise Grid Alliance. The OGF models its process on the Internet Engineering Task Force (IETF), and produces documents with many acronyms such as OGSA, OGSI, and JSDL. Organization The OGF has two principal functions plus an administrative function: being the standards organization for grid computing, and building communities within the overall grid community (including extending it within both academia and industry). Each of these function areas is then divided into groups of three types: ''working groups'' with a generally tightly defined role (usually producing a standard), ''research groups'' with a looser role bringing together people to discuss developments within their field and generate use cases and spawn working groups, and ''community groups'' (restricted to community functions). ...

Grid Computing
Grid computing is the use of widely distributed computer resources to reach a common goal. A computing grid can be thought of as a distributed system with non-interactive workloads that involve many files. Grid computing is distinguished from conventional high-performance computing systems such as cluster computing in that grid computers have each node set to perform a different task/application. Grid computers also tend to be more heterogeneous and geographically dispersed (thus not physically coupled) than cluster computers. Although a single grid can be dedicated to a particular application, commonly a grid is used for a variety of purposes. Grids are often constructed with general-purpose grid middleware software libraries. Grid sizes can be quite large. Grids are a form of distributed computing composed of many networked loosely coupled computers acting together to perform large tasks. For certain applications, distributed or grid computing can be seen as a special type of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GridWay
GridWay is an open-source meta-scheduling technology that enables large-scale, secure, reliable and efficient sharing of computing resources (clusters, computing farms, servers, supercomputers...), managed by different distributed resource management systems (DRMS), such as SGE, HTCondor, PBS or LSF, within a single organization (enterprise grid) or scattered across several administrative domains (partner or supply-chain grid). To this end, GridWay supports several Grid middlewares. Functionality GridWay provides end users and application developers with a scheduling framework similar to that found on local DRMS, allowing to submit, monitor, synchronize and control jobs by means of a DRMS-like command line interface (gwsubmit, gwwait, gwkill...) and DRMAA (an OGF standard). GridWay performs job execution management and resource brokering, allowing unattended, reliable, and efficient execution of jobs, array jobs, or complex jobs on heterogeneous, dynamic and loosely coupled G ...

Condor Cycle Scavenger
HTCondor is an open-source high-throughput computing software framework for coarse-grained distributed parallelization of computationally intensive tasks. It can be used to manage workload on a dedicated cluster of computers, or to farm out work to idle desktop computersso-called cycle scavenging. HTCondor runs on Linux, Unix, Mac OS X, FreeBSD, and Microsoft Windows operating systems. HTCondor can integrate both dedicated resources (rack-mounted clusters) and non-dedicated desktop machines (cycle scavenging) into one computing environment. HTCondor is developed by the HTCondor team at the University of Wisconsin–Madison and is freely available for use. HTCondor follows an open-source philosophy and is licensed under the Apache License 2.0. While HTCondor makes use of unused computing time, leaving computers turned on for use with HTCondor will increase energy consumption and associated costs. Starting from version 7.1.1, HTCondor can hibernate and wake machines based on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Independent Software Vendor
An independent software vendor (ISV), also known as a software publisher, is an organization specializing in making and selling software, as opposed to computer hardware, designed for mass or niche markets. This is in contrast to in-house software, which is developed by the organization that will use it, or custom software, which is designed or adapted for a single, specific third party. Although ISV-provided software is consumed by end users, it remains the property of the vendor. Software products developed by ISVs serve a wide variety of purposes. Examples include software for real estate brokers, scheduling for healthcare personnel, barcode scanning, stock maintenance, gambling, retailing, energy exploration, vehicle fleet management, and child care management software. An ISV makes and sells software products that run on one or more computer hardware or operating system platforms. Companies that make the platforms, such as Microsoft, AWS, Cisco, IBM, Hewlett-Packard, Red Hat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ranks as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simple Linux Utility For Resource Management
The Slurm Workload Manager, formerly known as Simple Linux Utility for Resource Management (SLURM), or simply Slurm, is a free and open-source job scheduler for Linux and Unix-like kernels, used by many of the world's supercomputers and computer clusters. It provides three key functions: * allocating exclusive and/or non-exclusive access to resources (computer nodes) to users for some duration of time so they can perform work, * providing a framework for starting, executing, and monitoring work, typically a parallel job such as Message Passing Interface (MPI) on a set of allocated nodes, and * arbitrating contention for resources by managing a queue of pending jobs. Slurm is the workload manager on about 60% of the TOP500 supercomputers. Slurm uses a best fit algorithm based on Hilbert curve scheduling or fat tree network topology in order to optimize locality of task assignments on parallel computers. History Slurm began development as a collaborative effort primarily b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UNICORE
UNICORE (UNiform Interface to COmputing REsources) is a grid computing technology for resources such as supercomputers or cluster systems and information stored in databases. UNICORE was developed in two projects funded by the German ministry for education and research (BMBF). In European-funded projects UNICORE evolved to a middleware system used at several supercomputer centers. UNICORE served as a basis in other research projects. The UNICORE technology is open source under BSD licence and available at SourceForge. History The concept of grid computing was first introduced in the book "The Grid: Blueprint for a New Computing Infrastructure" at the end of 1998. By 1997, the development of UNICORE was initiated for German supercomputer centers as an alternative for the Globus Toolkit. The first prototype was developed in the German UNICORE project, while the foundations for the production version were laid in the follow-up project UNICORE Plus, which ended in 2002. Follow ...

European Grid Infrastructure
European Grid Infrastructure (EGI) is a series of efforts to provide access to high-throughput computing resources across Europe using grid computing techniques. The EGI links centres in different European countries to support international research in many scientific disciplines. Following a series of research projects such as DataGrid and Enabling Grids for E-sciencE, the EGI Foundation was formed in 2010 to sustain the services of EGI. Purpose Science has become increasingly based on open collaboration between researchers across the world. It uses high-capacity computing to model complex systems and to process experimental results. In the early 21st century, grid computing became popular for scientific disciplines such as high-energy physics and bioinformatics to share and combine the power of computers and sophisticated, often unique, scientific instruments in a process known as e-Science. In addition to their scientific value, on 30 May 2008 The EU Competitiveness Council ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xgrid
Xgrid is a proprietary program and distributed computing protocol developed by the Advanced Computation Group subdivision of Apple Inc that allows networked computers to contribute to a single task. It provides network administrators a method of creating a computing cluster, which allows them to exploit previously unused computational power for calculations that can be divided easily into smaller operations, such as Mandelbrot maps. The setup of an Xgrid cluster can be achieved at next to no cost, as Xgrid client is pre-installed on all computers running Mac OS X 10.4 to Mac OS X 10.7. The Xgrid client was not included in Mac OS X 10.8. The Xgrid controller, the job scheduler of the Xgrid operation, is also included within Mac OS X Server and as a free download from Apple. Apple has kept the command-line job control mechanism minimalist while providing an API to develop more sophisticated tools built around it. The program employs its own communication protocol layered on to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
