Introduction

This is the place where information about the ATHENA workshop will be made available. ATHENA is the control framework of ATLAS. It is based on Gaudi. Getting started with ATHENA is quite difficult and one can easily get lost. The october workshop held at NIKHEF will provide a first introduction to ATHENA.

The aim of the workshop is:

get familiar with CMT (Configuration Management Tool). This is the environment used to run ATHENA and maintain/develop its packages.
introduce a beginner to ATHENA and its concepts such as Algorithms, Tools, DataStorage and the like
explain the usage of python scripts (jobOptions) in order to steer ATHENA
excersise on a part of the ATHENA-chain: do reconstruction and analysis

The aim of the workshop is not:

an introduction to C++ and python programming. Although experience in C++ is absolutely necessairy for using and understanding ATHENA we won't go into it. Little knowledge on python won't limit ones capabilities on using ATHENA.
give a detailed explaination of the technicalities behind CMT and ATHENA. Due to little time we won't go deep into the details.

In order to maximize efficiency of the latter parts of the tutorial, it is recommended to do the Pre-Tutorial before starting with the main tutorial! Preferably before the first session on monday, so that the topics covered will be more familiar. In case that the pre-tutorial is too difficult, one might prefer to do the pre-tutorial tuesday (morning).
