• CERNLIB: CERN Program Library

  The CERN Program Library is a large collection of general purpose programs maintained and offered in both source and object code form on the CERN central computers. Most of these programs were developed at CERN and are oriented towards the needs of a physics research laboratory. They are thus of a general mathematical or data-handling nature, applicable to a wide range of problems.

• PAW: The ``Physics Analysis Workstation''

  PAW is an interactive set of tools to assist physicists in the analysis and presentation of their data. It provides interactive graphical presentation and statistical or mathematical analysis, working on objects familiar to physicists like histograms, event files (Ntuples), vectors, etc.

• GEANT: Detector Description and Simulation Tool

  The GEANT program describes the passage of elementary particles through the matter. The principal applications of GEANT in High Energy Physics are:
  1. the tracking of particles through an experimental setup for simulation of detector response,
  2. the graphical representation of the setup and of the particle trajectories.

  GEANT4: Object-Oriented Toolkit for Simulation in HEP

  GEANT4 is a complete object-oriented re-design of the GEANT3 High Energy physics simulation code, augmented with many extensions needed for the latest generation of experiments. It is one of the main components of the general framework for the LHC off-line software.

• ORACLE: Central Database Support

  CERN has chosen ORACLE as the standard Relational Database Management System. The Central Database Support in the IT Division takes care of distributing this software, of providing advice and first line support and of the administration of some databases of general interest. Other tasks include the installation and testing of new releases of both the RDBMS and tools software.

• LHC++: Libraries for HEP Computing.

  LHC++ proposes a high-level physics analysis environment for LHC-era experiments. It uses object technology, in particular C++.

• RD45: A Persistent Object Manager for HEP

  RD45 is a DRDC project to investigate solutions to the problem of object persistence (frequently referred to as the ``I/O'' problem), for LHC-era HEP experiments and all kinds of objects (histograms, detector calibration geometry, production control, event data). The product of this development will be based upon a combination of commercial, standards-conforming Object Databases together with commercial, standards-conforming Mass Storage Systems.
