How is big data used in CERN?
Big Data Used By CERN CERN’s LHC records hundreds of millions of collisions between particles. These particles can achieve a speed of 99.9% of the speed of light because they accelerate around the collider.
How much data does CERN generate?
Even after the drastic data reduction performed by the experiments, the CERN DC processes on average one petabyte of data per day.
What is CERN data?
The CERN Data Centre is the heart of CERN’s entire scientific, administrative, and computing infrastructure. All services, including email, scientific data management and videoconferencing use equipment based here. The 470 000 processor cores and 11 000 servers run 24/7.
What is CERN How big is it what does it contain?
It consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator.
How much storage does CERN have?
At CERN, the bulk of the data (about 88 petabytes) is archived on tape using the CERN Advanced Storage system (CASTOR) and the rest (13 petabytes) is stored on the EOS disk pool system – a system optimized for fast analysis access by many concurrent users.
What computers CERN use?
There are now two computers at CERN, the original Ferranti Mercury and the IBM 7090, a transistorized and more powerful replacement for its predecessor, the IBM 709.
Which programming language is used in CERN?
Description. CERN maintained a program library written in FORTRAN for many years; development and maintenance were discontinued in 2003 in favour of ROOT, written in C++. ROOT development was initiated by René Brun and Fons Rademakers in 1994.
Is CERN data public?
This data set is now publicly available on the CERN Open Data Portal. Open source software to read and analyse the data is also available, together with the corresponding documentation.
Did CERN create Internet?
Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW) in 1989, while working at CERN. The web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world.
How much data does the Large Hadron Collider produce per second?
about one petabyte
Particles collide in the Large Hadron Collider (LHC) detectors approximately 1 billion times per second, generating about one petabyte of collision data per second.
Is CERN a computer?
Short for Conseil Europeen pour la Recherche Nuclaire, CERN is a laboratory established on September 29, 1954, and today is the world’s largest particle physics laboratory.
