CERN Program Library

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 <a href="/facts/CERN/y1gwRchm">CERN</a>. The application area of the library focuses on physics research, in particular <a href="/facts/High_energy_physics/YgIuyj2t">high energy physics</a>, involving general mathematics, <a href="/facts/Data_analysis/CNtARxLW">data analysis</a>, detectors simulation, data-handling, <a href="/facts/Numerical_analysis/QT9cYa9z">numerical analysis</a>, and others, applicable to a wide range of scientific problems. Many modules are written in the <a href="/facts/FORTRAN_77/m1KqjcMU">FORTRAN 77</a> language.
The major fields covered by the libraries contained therein were:

<ul><li><a href="/facts/Elementary_particle/CTFDM97U">Elementary particle</a> data</li>
<li>Graphics and plotting</li>
<li>Histograming</li>
<li><a href="/facts/I/O/WQTE8Jas">I/O</a> and structured data storage</li>
<li>Numerical analysis</li>
<li><a href="/facts/Statistics/DNPsKGYU">Statistics</a> and data analysis</li>
<li>Detector simulation and <a href="/facts/Hadron/C0sd1zty">Hadronic</a> <a href="/facts/Event_generator/dg8hCYfr">event generation</a></li></ul>
Lower-level parts of the CERN Program Library were most prominently used by the data analysis software <a href="/facts/Physics_Analysis_Workstation/ApHa8KMC">Physics Analysis Workstation</a> (PAW) and the detector simulation framework <a href="/facts/GEANT-3/wGC9QoQl">GEANT</a>, 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 a year. Besides legacy software dependency, for newer applications written in <a href="/facts/C%2B%2B/Et0F2qn9">C++</a>, CERNLIB is superseded by <a href="/facts/ROOT/Hk7ucczM">ROOT</a>.
