GridPP is a collaboration of particle physicists and computer scientists from the United Kingdom and CERN. They manage and maintain a distributed computing grid across the UK with the primary aim of providing resources to particle physicists working on the Large Hadron Collider (LHC) experiments at CERN. [1] They are funded by the UK's Science and Technology Facilities Council. The collaboration oversees a major computing facility called the Tier1 at the Rutherford Appleton Laboratory (RAL) along with the four Tier 2 organisations [2] of ScotGrid, NorthGrid, SouthGrid and LondonGrid (formerly LT2). The Tier 2s are geographically distributed and are composed of computing clusters at multiple institutes.
As of 2012 the GridPP infrastructure spans 18 UK institutions [3] and is major partner in the UK's National Grid Initiative as a part of the European Grid Infrastructure.
The original GridPP plan was drawn up in late 2000 [4] to provide the UK's contribution to the LHC Computing Grid and the EuropeanDataGrid project (now the European Grid Infrastructure). The drive behind these projects was to provide researchers working on the LHC experiments with suitable computing resources [5] and to extend the use of the technology to other communities. [6] The first GridPP proposal was accepted by PPARC, at the time the UK funding council responsible for funding particle physics related projects, and the collaboration officially began on 1 September 2001 with £17m of funding. [1] During this first phase of GridPP (2001 to 2004) the collaboration built the UK testbed, a working prototype for a grid that was linked to other similar systems around the world. In preparation for its use as a production infrastructure it analysed real data from a wide variety of experiments being run around the world in different institutions. In 2004 it was extended until September 2007 [7] to bring it up to the proposed LHC switch on date. By 2007 GridPP was a fully functioning production service [8] but the LHC switch on was still a year away so in September 2007 it received a further extension from STFC, receiving £30m of funding until March 2011. [9]
GridPP is in its fourth phase (2011–2014) having received more funding from the Science and Technology Facilities Council (STFC) to support the LHC experiments and other users. In late 2011 the project is providing over 29,000 CPUs [10] and 25,000TB of storage [11] to the worldwide grid infrastructure.
All of the UK universities and institutions with researchers working on the LHC are members. As of 2011 the list is as follows: [12]
ScotGrid is based across 3 main sites and primarily supports on-going research within the field of Particle Physics. The entire environment is monitored, maintained and developed by dedicated teams at each site, to ensure a fully operational system is available to the end user communities. [13]
LondonGrid is a joint collaboration of 5 institutes in the London region to provide high performance computing resources to the high energy physics community.
GridPP supports many disciplines and projects. This is a list of the different experiments or projects that actively use GridPP resources.
GridPP was originally created to support the experiments based at CERN using the LHC. The 4 main experiments supported are:
Alongside the experiments at the LHC GridPP also supports other international high energy physics experiments. These include:
GridPP, through the European Grid Infrastructure and its own efforts, supports many non-physics research disciplines.
The European Organization for Nuclear Research, known as CERN, is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954, it is based in Meyrin, western suburb of Geneva, on the France–Switzerland border. It comprises 23 member states. Israel, admitted in 2013, is the only non-European full member. CERN is an official United Nations General Assembly observer.
The Large Hadron Collider (LHC) is the world's largest and highest-energy particle collider. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundreds of universities and laboratories across more than 100 countries. It lies in a tunnel 27 kilometres (17 mi) in circumference and as deep as 175 metres (574 ft) beneath the France–Switzerland border near Geneva.
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-prints, and print and/or electronic publications." In 2014, IEEE eScience Conference Series condensed the definition to "eScience promotes innovation in collaborative, computationally- or data-intensive research across all disciplines, throughout the research lifecycle" in one of the working definitions used by the organizers. E-science encompasses "what is often referred to as big data [which] has revolutionized science... [such as] the Large Hadron Collider (LHC) at CERN... [that] generates around 780 terabytes per year... highly data intensive modern fields of science...that generate large amounts of E-science data include: computational biology, bioinformatics, genomics" and the human digital footprint for the social sciences.
LHC@home is a volunteer computing project researching particle physics that uses the Berkeley Open Infrastructure for Network Computing (BOINC) platform. The project's computing power is utilized by physicists at CERN in support of the Large Hadron Collider and other experimental particle accelerators.
The Rutherford Appleton Laboratory (RAL) is one of the national scientific research laboratories in the UK operated by the Science and Technology Facilities Council (STFC). It began as the Rutherford High Energy Laboratory, merged with the Atlas Computer Laboratory in 1975 to create the Rutherford Lab; then in 1979 with the Appleton Laboratory to form the current laboratory.
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.
The Science and Technology Facilities Council (STFC) is a United Kingdom government agency that carries out research in science and engineering, and funds UK research in areas including particle physics, nuclear physics, space science and astronomy.
The National E-Infrastructure Service (NES), formerly the National Grid Service, was an organisation for UK academics and researchers from 2004 through 2011. It was funded by two governmental bodies, Engineering and Physical Sciences Research Council (EPSRC) and the Joint Information Systems Committee (JISC).
The Nordic Data Grid Facility, or NDGF, is a common e-Science infrastructure provided by the Nordic countries for scientific computing and data storage. It is the first and so far only internationally distributed WLCG Tier1 center, providing computing and storage services to experiments at CERN.
The Worldwide LHC Computing Grid (WLCG), formerly the LHC Computing Grid (LCG), is an international collaborative project that consists of a grid-based computer network infrastructure incorporating over 170 computing centers in 42 countries, as of 2017. It was designed by CERN to handle the prodigious volume of data produced by Large Hadron Collider (LHC) experiments.
Computational particle physics refers to the methods and computing tools developed in and used by particle physics research. Like computational chemistry or computational biology, it is, for particle physics both a specific branch and an interdisciplinary field relying on computer science, theoretical and experimental particle physics and mathematics. The main fields of computational particle physics are: lattice field theory, automatic calculation of particle interaction or decay and event generators.
Christine Tullis Hunter Davies is a professor of physics at the University of Glasgow.
The search for the Higgs boson was a 40-year effort by physicists to prove the existence or non-existence of the Higgs boson, first theorised in the 1960s. The Higgs boson was the last unobserved fundamental particle in the Standard Model of particle physics, and its discovery was described as being the "ultimate verification" of the Standard Model. In March 2013, the Higgs boson was officially confirmed to exist.
