• Currently 6 sites and OpsCentre
• DIAS, NUIG, TCD, UCC, UCD, QUB
• More sites in 2005 (MiniGateWays)
• VOs CosmoGrid, MarineGrid, TestGrid, Webcom-G,
  EGEE/LCG
• National Services and helpdesk at TCD

3

• Donated by DELL Ireland
• Dell 1750
• 2GB Ram
• SCSI (2 x 160 GB)
• Extending Grid access to additional third level
  institutions
• Rollout started Jan05
• Sites chosen by competitive survey

4

• Based on Xen Linux Kernel
• Six virtual machines on one physical computer
• Minimises (hardware) cost associated with joining
  the Grid
• Out performs UserMode-Linux by a factor of 10

5

• Catch-all Gateway proposed to function as access
  point for Government institutions (GSI, Met
  Eireann, Marine Institute, ....)
• HEC Gateway to provide access to the recently
  announced High Performance Computing Centre -
  1000 CPUs.
• will connect to DIAS and NUIG CosmoGrid clusters

csTCDie connected to LCG-2 since Oct04
7

• This is not without its problems
• csTCDie on LCG2 and Grid-Ireland, no Multi VO
  support in R-GMA, but expected later.
• Grid-Ireland has helped enhance software
• Routing Queue, Heterogeneity - Fedora, IRIX, AIX
• Info-Provider problems, accounting(?)
• Transition to Quattor/SL3
• Still yet an unknown, test on TestGrid

8

• Mostly MPI application developers
• MPI installed on sites using INFN Howto
• 110 (x2) CPU goes live at UCD - Feb 7th
• 2 GB RAM per processor
• Intel EM64T, 3.2 GHz CPU - RH EL 3.0
• Routing Queue connection to Grid-Ireland

csTCDie Site
11

• Multifaceted Testbed
• Validating latest software release
• Testing experimental middleware
• Porting to non-reference platforms
• Implements multiple sites
• Replicates setup of some sites
• Special router - layer II filtering

12

• LCG officially only supports RH7.3 and Scientific
  Linux
• Porting has involved many man-months effort
• Ports for Fedora, IRIX, AIX
• Now working on Mac OSX
• Localised Autobuild system - rebuilds nightly
• Local software - SANTA-G

13

• Grid is ideologically heterogeneous
• Means for reliably measuring Grid Performance
• Tests Grid resources at different levels - WN
  level, Cluster level,
• Collaboration with University of Cyprus
• 11separate tests

14

• Workshop for grid sysadmins
• September 20th-22nd
• 2-day introduction to LCG2
• 1-day technical discussions
• First Users course (Dec 9th 10th)
• User Project provided template for writing
  Grid-enabled application (non MPI).
• Second Users course (Jan 21st)
• focus on quick start introduction to Grid
