CC-J Presentation

This presentation provides an overview of the simulation requirements, regional data analysis center, and technical details of the PHENIX Collaboration. It discusses the importance of the collaboration in the computing strategy and leveraging existing facilities. It also highlights the need for simulation capabilities and the resources provided by the regional center. Finally, it emphasizes the presence of PHENIX in Asia and the involvement of Asian thesis students.

Presentation Transcript

  1. CC-J Presentation • PHENIX Collaboration Viewpoint W.A. Zajc (~10 min) • Simulation requirements • Regional data analysis center • PHENIX-J Perspective H. En’yo (~10 min) • Physics analysis (spin and heavy ions) • Center for Spin Analysis • Technical Detail T. Ichihara (~30 min) • Scope • Plan • Schedule W.A. Zajc

  2. Overview • PHENIX CC-J • Has been and continues to be an integral part of PHENIX’s computing strategy. • Will be the dominant source of our simulation capability. • Will provide an outstanding regional analysis center for PHENIX collaborators in Asia. • Will leverage existing and planned facilities of RIKEN Wako campus. • Important to proceed now so that these resources are in place before upcoming commissioning and data runs. W.A. Zajc

  3. Simulation Requirements exceed all known sources of computing: • Baseline sample of fully simulated events: • Production of 5M simulated events/year requires ~8K SPECInt95’s running at 100% duty factor • Note this represents one simulated event for every 200 real events(!) • Acceptances: • Multi-dimensional matrices in (h,f,p,species,configuration,field,…) • Parameterizations of same • Backgrounds • Dedicated studies of particular sources • Note PHENIX is an “edgy” detector • Machine (beam-gas, pairs, etc.) • Model studies • Would like full simulations from more than one generator • B-E, DCC, ... W.A. Zajc

  4. Regional Center • Solves existing problem of trans-Pacific network bandwidth • Provides important resources for pursuing analyses of special interest to Japanese collaborators For example • Spin • Hadrons • Thermal radiation • Provides local clone of RCF environment for Japanese collaborators (especially new students) • Leverages existing RIKEN and university resources (Facilities and staff) • Establishes highly visible PHENIX presence in Japan W.A. Zajc

  5. Thesis Students • Snapshot as of Aug-98: • Currently 17 of 28 thesis students are from Asian institutions W.A. Zajc
