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]].<ref name="cern2014">{{Cite web

The '''CERN Program Library''' or '''CERNLIB''' was a collection of [[FORTRAN77]] libraries and modules, developed at [[CERN]]. Its content ranged from more specialized [[data analysis]] of [[high energy physics]] to general purpose [[numerical analysis]]. 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 (program)|GEANT]] (which themselves were contained in the CERN Program Library).

}}</ref> 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.

The major fields covered by the libraries contained therein were:

Its content ranged from more specialized [[data analysis]] of [[high energy physics]] to general purpose [[numerical analysis]]. Lower-level parts of the CERN Program Library were most prominently used by the data analysis software [[Physics Analysis Workstation|PAW]] (PAW) and the detector simulation framework [[GEANT (program)-3|GEANT]], both of (which themselvesare werealso containedpart inof the CERN Program Library).

CERN Program Library used the year as its version, with not explicitly denoted minor revisions within a year. Besides legacy software dependency, for newer applications written in [[C++]], CERNLIB is now superseded by [[ROOT]].

==Status==

The developmentDevelopment and support for CERNLIB was discontinued in 2003.<ref name="cern2014"/> Libraries arewere still available "as is" "for ever" from [https://web.archive.org/web/20060520110912/http://cernlib.web.cern.ch/cernlib/version.html the CERNLIB web site] but with no new code, no user support and no port to IA64[[IA-64]].

The code was revitalized in 2022,<ref name ="CERNLIB status">{{cite arXiv | eprint=2303.07506 | last1=Schwickerath | first1=Ulrich | last2=Verbytskyi | first2=Andrii | title=CERNLIB status | date=2023 | class=physics.comp-ph }}</ref> multiple patches were added and as of 2023 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.
