Computing in Saclay

Saclay has some envolvement in the Lyon computing center

In Saclay: 1 DEC UNIX with KAI

problem to get D0 code installed because no « official »releases on 1 PC sous LINUX avec KAI

1 PC under Linux Code Releases regularly installed

Link with FNAL link RENATER to ATM 155Mb, 100

mb shared by Saclay and other users

Being negociated: ~1 Mb dedicated between Saclay and FNAL

Software Activities

Main involvement: testing D0STAR/Simpp Pre-Simpp era: testing D0gstar

output (In Fortran) some bugs found in GEANT 3.21 Some problems found in geometry

definition for some detectors After Simpp:

code in C++ to build hbook histos for (almost) available information (generated tracks, hits, digi, reco,..)

Code for writting « general » Ntuple with variables above

maintenance and developpements Tools for studying tracking
