Outline Enabling Grids for E-scienc. E • Grid. ICE – Brief history – Facts snapshot – Discussion INFSO-RI-508833 EGEE User Forum, CERN, Geneva, Switzerland, March 1 -3, 2006 2
Brief history Enabling Grids for E-scienc. E • Started with concept EDT monitoring tool 2002 – Adopted by LCG nov 2003 • Good support till end of 2007 • Slow support work end of 2008 – Work made to integrate new lemon in production & SL 4 server distribution support • ~ no support in 2009 • Problem with little projects (EU-India. Grid 2, …) • Some people asked for development INFSO-RI-508833 EGEE User Forum, CERN, Geneva, Switzerland, March 1 -3, 2006 3
2008 Enabling Grids for E-scienc. E • Grid. ICE server instances in 2008 EGEE-SWE RDIG EGEE-SEE Grid. it GILDA CMS ATLAS EUMed. Grid EUChina. GRID EU-India. Grid Baltic. Grid EELA Be. Grid e. NMR SCOPE CYBERSAR • Development status at 2008 end: – Fabric integration with lemon 2. 13. x in production but some problems to solve in JM – Camera ready DB enhancement (partitioning) for overall performance boost – Almost ready server distribution for SL 4 (lack only rpms build) INFSO-RI-508833 EGEE User Forum, CERN, Geneva, Switzerland, March 1 -3, 2006 4

Recycling… Enabling Grids for E-scienc. E • Measurement specification for Grid. ICE-Le. MON compatible probes are provided for: – CPUINFO (10100) – OS (10101) – ALIVE (10102) – REGFILES (10103) – DAEMON (10104) – UPTIME (11001) – CPU (11011) – MEMORY (11021) – SWAP (11022) – PROCESSES (11031) – DISK (11101) – SOCKETS (11201) – NETWORK (11202) – Jobs (10106) – LRMSInfo (10107) INFSO-RI-508833 EGEE User Forum, CERN, Geneva, Switzerland, March 1 -3, 2006 9
Recycling… (2) Enabling Grids for E-scienc. E • LRMSInfo for HLRmon – Work made around Jan-Apr 2009 -> some low level measurements for referee control / SLA check – Was used with a manual run on ROC-IT T 2 s o collect mainly: CPUs (chips), cores, slots and power (KIS 2 K) – Work of integration in a more widely automated infrastructure stopped. (? Some minor security complaints? very simple to overcome!) Infrastructure Layout • Notification system – Development of a new general purpose notification service with the experience gained with Grid. ICE server in particular from CMS SC 04 (parents/children notification grouping/scope) INFSO-RI-508833 EGEE User Forum, CERN, Geneva, Switzerland, March 1 -3, 2006 10
