Rocks Cluster Distribution
Rocks Cluster Distribution (originally NPACI Rocks) is a Linux distribution intended for high-performance computing (HPC) clusters. It was started by National Partnership for Advanced Computational Infrastructure and the San Diego Supercomputer Center (SDSC) in 2000. It was initially funded in part by an NSF grant (2000–07), but was funded by the follow-up NSF grant through 2011. Distribution Rocks was initially based on the Red Hat Linux (RHL) distribution, however modern versions of Rocks were based on CentOS, with a modified Anaconda installer that simplifies mass installation onto many computers. Rocks includes many tools (such as Message Passing Interface (MPI)) which are not part of CentOS but are integral components that make a group of computers into a cluster. Installations can be customized with additional software packages at install-time by using special user-supplied CDs (called "Roll CDs"). The "Rolls" extend the system by integrating seamlessly and automa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions inten ...

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 and then from Univa Corporation. 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 Services (AWS) announced on June 24, 2018. The original Grid Engine open-source project website closed in 2010, but versions of the technology are still available under ...

Cluster Computing
A computer cluster is a set of computers that work together so that they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (e.g. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, or different hardware. Clusters are usually deployed to improve performance and availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability. Computer clusters emerged as a result of convergence of a number of computing trends including th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CNK Operating System
Compute Node Kernel (CNK) is the node level operating system for the IBM Blue Gene series of supercomputers.''Euro-Par 2004 Parallel Processing: 10th International Euro-Par Conference'' 2004, by Marco Danelutto, Marco Vanneschi and Domenico Laforenza pages 835''Euro-Par 2006 Parallel Processing: 12th International Euro-Par Conference'', 2006, by Wolfgang E. Nagel, Wolfgang V. Walter and Wolfgang Lehner page The compute nodes of the Blue Gene family of supercomputers run ''Compute Node Kernel'' (CNK), a lightweight kernel that runs on each node and supports one application running for one user on that node. To maximize operating efficiency, the design of CNK was kept simple and minimal. It was implemented in about 5,000 lines of C++ code. Physical memory is statically mapped and the CNK neither needs nor provides scheduling or context switching, given that at each point it runs one application for one user. By not allowing virtual memory or multi-tasking, the design of CNK aimed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cray Linux Environment
UNICOS is a range of Unix and after it Linux operating system (OS) variants developed by Cray for its supercomputers. UNICOS is the successor of the Cray Operating System (COS). It provides network clustering and source code compatibility layers for some other Unixes. UNICOS was originally introduced in 1985 with the Cray-2 system and later ported to other Cray models. The original UNICOS was based on UNIX System V Release 2, and had many Berkeley Software Distribution (BSD) features (e.g., computer networking and file system enhancements) added to it. Development CX-OS was the original name given to what is now UNICOS. This was a prototype system which ran on a Cray X-MP in 1984 before the Cray-2 port. It was used to demonstrate the feasibility of using Unix on a supercomputer system, before Cray-2 hardware was available. The operating system revamp was part of a larger movement inside Cray Research to modernize their corporate software: including rewriting their most impo ...

Scientific Linux
Scientific Linux (SL) was a Linux distribution produced by Fermilab, CERN, DESY and by ETH Zurich. It is a free and open-source operating system based on Red Hat Enterprise Linux. This product is derived from the free and open-source software made available by Red Hat, but is not produced, maintained or supported by them. In April 2019, it was announced that feature development for Scientific Linux would be discontinued, but that maintenance will continue to be provided for the 6.x and 7.x releases through the end of their life cycles. Fermilab and CERN will utilize CentOS Stream and AlmaLinux for their deployment of 8.x release instead. History Fermilab already had a Linux distribution known as Fermi Linux, a long-term support release based on Red Hat Enterprise Linux. CERN was creating their next version of CERN Linux, also based on RHEL. CERN contacted Fermilab about doing a collaborative release. Connie Sieh was the main developer and driver behind the first prototypes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ganglia (software)
Ganglia is a scalable, distributed monitoring tool for high-performance computing systems, clusters and networks. The software is used to view either live or recorded statistics covering metrics such as CPU load averages or network utilization for many nodes. Ganglia software is bundled with enterprise-level Linux distributions such as Red Hat Enterprise Level (RHEL) or the CentOS repackaging of the same. Ganglia grew out of requirements for monitoring systems by Berkeley (University of California) but now sees use by commercial and educational organisations such as Cray, MIT, NASA and Twitter. Ganglia It is based on a hierarchical design targeted at federations of clusters. It relies on a multicast-based listen/announce protocol to monitor state within clusters and uses a tree of point-to-point connections amongst representative cluster nodes to federate clusters and aggregate their state. It leverages widely used technologies such as XML for data representation, XDR for com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
