Networking and ITS Issues for PHENIX* Charles F. Maguire

Learn about the role of networking and ITS for the PHENIX detector in physics research, including collaborations and data transport methods. Vanderbilt University plays a crucial role in subsystem supervision and simulation data generation. Discover how advancements in transport technology facilitate efficient data transfer. Collaboration with gridFTP ensures secure transmission. Proposals include importing real data via gridFTP, proving successful for international connections.

  4. Vanderbilt Role in PHENIX • Supervisor of 3 subsystems • Pad Chambers • New Time-of-Flight West • Simulation Software • Simulation Responsibility • Generate huge amounts of simulated data to check real analyses • Simulations done on ACCRE farm (5 TBytes in past 6 weeks) • Results are transported over the Internet to BNL at 10 Mbytes/second • ACCRE can generate simulations faster than we can ship them • Now exploring new faster modes of transport, up to 60 MBytes/secondCollaboration will request us to use gridFTP for this work (security for them) • New Proposal to DOE Planned for the Fall • Will import hundreds of TBytes of real data from BNL to ACCRE via gridFTP100 TBytes at 60 MBytes/second takes 20 daysProved to work this past Spring for a connection from BNL to Japan • Data will be reconstructed on ACCRE • Reconstruction results (tens of TBytes) will be immediately shipped back to BNL • The speed, reliability, and transparency of the network is the vital element Networking and ITS
