5AMS Computing. MC Production.
- Computer simulation of the detector response is a
good possibility to study not only detector
performance, but also to test HW and SW solutions
that will be used for AMS-02 data processing. - Distributed trial MC production was started in
April 2003 (Apr-June, July-October) - Data are generated in 16 Universities in Asia,
Europe and USA, transmitted to AMS_at_CERN and
available for the analysis. - Transmission, book-keeping, process communication
programs been debugged and the same programs will
be used for AMS-02 data handling.
6AMS Computing. MC production.
- Local-cern book-keeping Release 1.0 (M.Boschini
et al) - Stress-tested in July-August
- Mantained by Milano group

MC production
- To buy the bulk of computing power later to have
better price/performance ratio - build system gradually
