Production status

T. Wenaus, Paris simu workshop 1/95

  • 0.6.0 production over holiday by Fred Kral, SLAC and LBNL
    • limited by availability of generator files, disk space
    • a few crashes due to a bug in DCH, found and fixed
    • backgd events in the tens of thousands run successfully
    Becomes (with completing digitization dbio I/O) my top priority when I get back: get serious production going at SLAC and offsite
    • remote sites like RAL and IN2P3 with people willing to participate early and help implement the system can get started with us setting things up right away
    • Fred Kral, Ed Frank helping
    • Propose phone conference of interested parties Mon Jan 29, 8:30am PST.

Sites expressing interest in production

  • SLAC
    • Unix farm ready and in use by BaBar (eg. DIRC beam test)
    • RS6000
    • Tape staging facility in place
  • LBL (Fred Kral)
    • Suns, alphas
  • Rutherford (Neil Geddes, Paul Dauncey)
    • Alphas
    • Willingness to participate early and assist in commissioning of production system
  • IN2P3, Lyon (Jean-Louis Narjoux, Dominique Boutigny)
    • HP, IBM
    • bbsim running on HPs; IBMs must resolve preprocessing problem (vms2f90 needed? We need to know ASAP)
    • Willingness to participate early and assist in commissioning of production system
    • 10,000-20,000 3090 units available in 1-6/96
  • U. of Colorado (Tricia Rankin)
    • Seven alphas (shared with CLEO)
    • Enlist Hwanbae Park to assist in setting up production?
  • U Pennsylvania (Larry Gladney)
    • 8 processor SP2, SparcServer 670 (MP), 2xRS6000 350 (exclusive)
    • BaBar code installed on suns; in progress on IBMs (old info)
  • Vanderbilt (Bob Panvini)
    • 14 model 200 4/233 alphas; 2200 specInt92
    • Tentative; were awaiting funding decision which would set scale of BaBar participation (not heard from recently)

Production requirements

Trigger group requirements increasing rapidly from requirements measured in CPU months to CPU years over the next few months. Will get more quantitative soon.
