ALEPH Offline and Analysis

[Computers] [Software] [Data] [Desktop] [Subgroups]

The Aleph offline system consists of software and hardware to process the Aleph data from the raw data tapes to the results of the physics analysis. Introductory material for computing in the Aleph offline environment is given here. We have compiled some statistics and given a number of talks about the system.

Computer systems

Supported systems and Aleph computers at CERN
LSF batch system
