Cyberinfrastructure
United States federal government agencies use the term cyberinfrastructure to describe research environments that support advanced data acquisition, data storage, data management, data integration, data mining, data visualization and other computing and information processing services distributed over the Internet beyond the scope of a single institution. In scientific usage, cyberinfrastructure is a technological and sociological solution to the problem of efficiently connecting federal laboratories, large scales of data, processing power, and scientists with the goal of enabling novel scientific discoveries and advancements in human knowledge. Origin The term National Information Infrastructure had been popularized by Al Gore in the 1990s. This use of the term "cyberinfrastructure" evolved from the same thinking that produced Presidential Decision Directive NSC-63 on Protecting America's Critical Infrastructures (PDD-63). PDD-63 focuses on the security and vulnerability of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E-Science
E-Science or eScience is computationally intensive science that is carried out in highly distributed network environments, or science that uses immense data sets that require grid computing; the term sometimes includes technologies that enable distributed collaboration, such as the Access Grid. The term was created by John Taylor, the Director General of the United Kingdom's Office of Science and Technology in 1999 and was used to describe a large funding initiative starting in November 2000. E-science has been more broadly interpreted since then, as "the application of computer technology to the undertaking of modern scientific investigation, including the preparation, experimentation, data collection, results dissemination, and long-term storage and accessibility of all materials generated through the scientific process. These may include data modeling and analysis, electronic/digitized laboratory notebooks, raw and fitted data sets, manuscript production and draft versions, pre ...

Supercomputer Sites
A supercomputer is a type of computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2022, supercomputers have existed which can perform over 1018 FLOPS, so called Exascale computing, exascale supercomputers. For comparison, a desktop computer has performance in the range of hundreds of gigaFLOPS (1011) to tens of teraFLOPS (1013). Since November 2017, all of the TOP500, world's fastest 500 supercomputers run on Linux-based operating systems. Additional research is being conducted in the United States, the European Union, Taiwan, Japan, and China to build faster, more powerful and technologically superior exascale supercomputers. Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in various fields, ...

National Digital Information Infrastructure And Preservation Program
The National Digital Information Infrastructure and Preservation Program (NDIIPP) of the United States was an archival program led by the Library of Congress to preserve and provide access to digital resources. The program convened several working groups, administered grant projects, and disseminated information about digital preservation issues. The U.S. Congress appropriated funds to establish the program in 2000, and official activity specific to NDIIPP itself wound down between 2016 and 2018. The Library of Congress was chosen to lead the initiative because of its role as one of the leading providers of high-quality content on the Internet. The Library of Congress formed a national network of partners dedicated to preserving specific types of digital content that is at risk of loss. In July 2010, the Library of Congress launched the National Digital Stewardship Alliance (NDSA) to extend the work of NDIIPP to more partner institutions. The organization, which has been hosted by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Storage Resource Broker
Storage Resource Broker (SRB) is data grid management computer software used in computational science research projects. SRB is a logical distributed file system based on a client-server architecture which presents users with a single global logical namespace or file hierarchy. Essentially, the software enables a user to use a single mechanism to work with multiple data sources. Description SRB provides a uniform interface to heterogeneous computer data storage resources over a network. As part of this, it implements a logical namespace (distinct from physical file names) and maintains metadata on data-objects (files), users, groups, resources, collections, and other items in an SRB metadata catalog (MCAT) stored in a relational database management system. (Reprint from November 30 – December 3, 1998) System and user-defined metadata can be queried to locate files based on attributes as well as by name. SRB runs on various versions of Unix, Linux, and Microsoft Windows. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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").
