ZARAH is the central ZEUS data analysis facility. It provides the computing infrastructure and support for the ZEUS event data analysis and reconstruction.
The core of the ZARAH facility is a computation cluster which consists of the PC based batch farm and the storage facilities of the experiment. The access to the ZEUS event repository is highly optimized through the implementation and usage of the special services like zesLite tag database for an efficient event selection and a disk cache system for the data storage and transfer between the tape repository and the farm nodes.
The web content
This web portal describes the services offered by the ZARAH facility. It is mostly useful for the physicists who work on the ZEUS data analysis. It provides general information for the beginners and on the other hand describes many practical details of the analysis.
We hope that the information presented here can easily guide you through the practical issues you meet in a daily work for ZEUS. If you think some information is missing, please do not hesitate to tell us your opinion.
