The CERN Program Library ( CERNLIB ) is a collection of general purpose software libraries and program modules for scientific computing, developed at the European Organization for Nuclear Research CERN . The application area of the library focuses on physics research, in particular high energy physics , involving general mathematics, data analysis , detectors simulation, data-handling, numerical analysis , and others, applicable to a wide range of scientific problems. Many modules are written in the FORTRAN 77 language.
4-478: The major fields covered by the libraries contained therein were: Lower-level parts of the CERN Program Library were most prominently used by the data analysis software Physics Analysis Workstation (PAW) and the detector simulation framework GEANT , both of which are also part of the CERN Program Library. CERN Program Library used the year as its version, with not explicitly denoted minor revisions within
8-493: A year. Besides legacy software dependency, for newer applications written in C++ , CERNLIB is superseded by ROOT . Development and support for CERNLIB was discontinued in 2003. Libraries were still available "as is" "for ever" from the CERNLIB web site but with no new code, no user support and no port to IA-64 . The code was revitalized in 2022, multiple patches were added and as of 2023
12-503: The code can be compiled on multiple architectures either with its native build system imake or with the CMake . The revitalized version is based on the CERNLIB release 2006. Physics Analysis Workstation The Physics Analysis Workstation (PAW) is an interactive, scriptable computer software tool for data analysis and graphical presentation in high-energy physics . The development of this software tool started at CERN in 1986, it
16-516: Was optimized for the processing of very large amounts of data. It was based on and intended for inter-operation with components of CERNLIB , an extensive collection of Fortran libraries. PAW had been a standard tool in high energy physics for decades, yet was essentially unmaintained. Despite continuing popularity as of 2008, it has been losing ground to the C++ -based ROOT package. Conversion tutorials exist. In 2014, development and support were stopped. PAW uses its own scripting language. Here
