Enhancing Home Computing: Challenges and Solutions in Modern Networking

Join us for an enlightening discussion led by experts in computing, where we address pressing issues in home computing networks. Stefano Belforte opens with an introduction to the current landscape, followed by Rick St. Denis's insights on SAM, and an open discussion about our computing needs. Frank Wuerthwein dives into GRID politics, exploring the balance of costs and contributions. Feedback from participants will be collected for future planning. Let's collaborate to enhance system specifications and priorities for next-generation applications.

Presentation Transcript

  1. Computing at home: How are you doing ?What are the most pressing problems ? • Listen to talks trying to find the answers, then ask questions • INTRODUCTION (Stefano Belforte) 5min • SAM (Rick St.Denis) 15min • Is that what we want (open discussion) 20min • GRID POLITICS (Frank Wuerthwein) 10min • Can not make exahustive discussion here, nor can listen to everybody, nor claim to have the full feedback now • At least make sure everybody knows what is happening • Provide some immediate feedback now, but mostly in the following days/weeks (e.g. via e-mail to ICRB) to offline/DH leaders to help them finalize SAM specs and prioritities • I will be glad to collate feedbacks in a coherent frame Introduction Stefano Belforte - INFN Trieste

  2. Computing at home: the scenery • CDF has as much CPU/disk as money can buy (and people manage) • CAF: more then x10 the computing we thought 2 years ago • Two telltale signals: • 30% of FNAL CAF is non-FNAL-owned • dCAFs sprouting all around • Interpretation: time to expand offsite • Next frontier software: SAM + GRID (JIM) • SAM: transparent access to FNAL data from everywhere • AND data import to FNAL store (offsite MC) • GRID : merge with “LHC”, solve Authorization w/o Kerberos5 • Once remote computing is technically feasible.. Politcs : • Is it needed ? Or simply welcome ? • Is it a contribution ? Or a cost ? Introduction Stefano Belforte - INFN Trieste

  3. Besides softwarethe network !! Kindly got 2 slides from Phil Demar (CD networking group) Stefano Belforte - INFN Trieste

  4. Current Status: FNAL WAN Capabilities • Off-Site network link currently = 622Mb/s (OC12): • Link provided by ESnet (DOE network for the National Labs) • ESnet link upgraded from 155Mb/s (OC3) in December, 2002 • Dependent on DOE approval & funding for next upgrade (2.4 Gb/s) • Unclear when that upgrade may occur • Second off-site OC3 (MREN link) now only used for redundancy • Outbound traffic (blue line) increased 200% in 2002: • Daily outbound peaks (magenta line) > 200 Mb/s • Last week’s outbound traffic breakdown (by experiment) Introduction slide by Phil Demar (CD)

  5. Plans for StarLight Dark Fiber • FNAL working on procuring dark fiber to StarLight: • StarLight = International optical network exchange pt. in Chicago • Many US & International research networks connect to StarLight • StarLight dark fiber procurement (hopefully…) completed in this FY • Dark fiber offers potential for very high, scalable bandwidth • Bandwidth limited only by optical (DWDM) equipment supporting it • Initial DWDM configuration likely to be one or two 2.4 Gb/s λ’s • Additional λ’s could be added with additional DWDM modules • ESnet link to remain FNAL’s production network path • Will pursue ESnet link upgrades as WAN loads increase • Starlight Project’s purpose is WAN system / network research • StarLight link could be used for excess (overflow) production traffic • StarLight link could also support new, next generation applications requiring higher bandwidth than ESnet provides Introduction slide by Phil Demar (CD)
