Computing System
|
The ATLAS computing system will be designed to analyse
the data produced by the ATLAS detectors. The amount of data will
be huge. To get a feeling, note that the English version of the
Bible (Old and New Testament) can be stored on a floppy disk of
1.4 Megabytes. The annual ATLAS data volume would need 700 million
such disks. This stack of disks reaches from Geneva to Moscow.
To analyse these data, a compute power equivalent to 50,000 of todays PCs will be needed. The software to extract the physics results will be produced as a communal effort from many people in the ATLAS institutes. In order to ensure the required software quality, new methods for software engineering and project management will be required. |
