CERN Program Library

The CERN Program Library or CERNLIB is a collection of FORTRAN77 libraries and modules, maintained "as is" by CERN. Its content ranges from more specialized data analysis of high energy physics to general purpose numerical analysis. Lower-level parts of the CERN Program Library are most prominently used by the data analysis software PAW and the detector simulation framework GEANT (which themselves are contained in the CERN Program Library).

The major fields covered by the libraries contained therein are:

• Detector simulation
• Elementary particle data
• Graphics and plotting
• Hadronic event generation
• I/O and structured data storage
• Numerical analysis
• Statistics and data analysis

CERN Program Library uses 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 Besides legacy software dependency, for newer applications written in C++, CERNLIB is mostly superseded by ROOT.

Included applications

The CERNLIB contains the libwww, the Line Mode Browser and the CERN httpd.

Status

The development and support for CERNLIB was discontinued in 2003. Libraries will be continued to be provided "as is" "for ever" but with no new code, no user support and no port to IA64. Recompilations will be done for major new Linux versions, but must be tested by the experiments. If the tests fail, the last working frozen version will be kept: this would be the start of a "museum" system. The CERNLIB build...
