GLite
gLite (pronounced "gee-lite") is a middleware computer software project for grid computing used by the CERN LHC experiments and other scientific domains. It was implemented by collaborative efforts of more than 80 people in 12 different academic and industrial research centers in Europe. gLite provides a framework for building applications tapping into distributed computing and storage resources across the Internet. The gLite services were adopted by more than 250 computing centres, and used by more than 15000 researchers in Europe and around the world. History After prototyping phases in 2004 and 2005, convergence with the LHC Computing Grid (LCG-2) distribution was reached in May 2006, when gLite 3.0 was released, and became the official middle-ware of the Enabling Grids for E-sciencE (EGEE) project which ended in 2010. Development of the gLite middle-ware was then taken over by the European Middleware Initiative, and is now maintained as part of the EMI software stack. ...

European Middleware Initiative
The European Middleware Initiative (EMI) was a computer software platform for high performance distributed computing. It was developed and distributed directly by the ''EMI project''. It was the base for other grid middleware distributions used by scientific research communities and distributed computing infrastructures all over the world especially in Europe, South America and Asia. EMI supported broad scientific experiments and initiatives, such as the Worldwide LHC Computing Grid (for the Large Hadron Collider). The EMI middleware was a cooperation among three general purpose grid platforms, the Advanced Resource Connector, gLite and UNICORE and the ''dCache'' storage software. The project ended on 30 April 2013. Purpose The purpose of the EMI distribution is to consolidate, harmonize and support the original software platforms, evolve and extend them. Redundant or duplicate services resulting from the merging are deprecated, in favour of new services added to satisfy use ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platform LSF
IBM Spectrum LSF (LSF, originally Platform Load Sharing Facility) is a workload management platform, job scheduler, for distributed high performance computing (HPC) by IBM. Details It can be used to execute batch jobs on networked Unix and Windows systems on many different architectures. LSF was based on the ''Utopia'' research project at the University of Toronto. In 2007, Platform released ''Platform Lava'', which is a simplified version of LSF based on an old version of LSF release, licensed under GNU General Public License v2. The project was discontinued in 2011, succeeded by OpenLava. In January, 2012, Platform Computing was acquired by IBM. The product is now called IBM Spectrum LSF. IBM Spectrum LSF Community Edition is a no-charge community edition of the IBM Spectrum LSF workload management platform.

OpenLDAP
OpenLDAP is a free, open-source implementation of the Lightweight Directory Access Protocol (LDAP) developed by the OpenLDAP Project. It is released under its own BSD-style license called the OpenLDAP Public License. LDAP is a platform-independent protocol. Several common Linux distributions include OpenLDAP Software for LDAP support. The software also runs on BSD-variants, as well as AIX, Android, HP-UX, macOS, OpenVMS, Solaris, Microsoft Windows (NT and derivatives, e.g. 2000, XP, Vista, Windows 7, etc.), and z/OS. History The OpenLDAP project was started in 1998 by Kurt Zeilenga. The project started by cloning the LDAP reference source from the University of Michigan where a long-running project had supported development and evolution of the LDAP protocol until that project's final release in 1996. , the OpenLDAP project has four core team members: Howard Chu (chief architect), Quanah Gibson-Mount, Hallvard Furuseth, and Kurt Zeilenga.

Sun Grid Engine
Oracle Grid Engine, previously known as Sun Grid Engine (SGE), CODINE (Computing in Distributed Networked Environments) or GRD (Global Resource Director), was a grid computing computer cluster software system (otherwise known as a batch-queuing system), acquired as part of a purchase of Gridware, then improved and supported by Sun Microsystems and later Oracle. There have been open source versions and multiple commercial versions of this technology, initially from Sun, later from Oracle, then from Univa Corporation, and later from HPC Gridware as Gridware Cluster Scheduler. The open source version is still under active development under the SISSL license as Open Cluster Scheduler. On October 22, 2013 Univa announced it acquired the intellectual property and trademarks for the Grid Engine technology and that Univa will take over support. Univa has since evolved the Grid Engine technology, e.g. improving scalability as demonstrated by a 1 million core cluster in Amazon Web Serv ...

Secure Sockets Layer
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible. The TLS protocol aims primarily to provide security, including privacy (confidentiality), integrity, and authenticity through the use of cryptography, such as the use of certificates, between two or more communicating computer applications. It runs in the presentation layer and is itself composed of two layers: the TLS record and the TLS handshake protocols. The closely related Datagram Transport Layer Security (DTLS) is a communications protocol that provides security to datagram-based applications. In technical writing, references to "(D)TLS" are often seen when it applies to both versions. TLS is a proposed Internet Engineering Task Force (IETF) standard, first def ...
