TG Quarterly Meeting Breckenridge, CO Apr 11, 2007 CSE-Online Science Gateway  Production Date: Mar 9, 2007  Developed under ITR program  DAC Community Allocation  MRAC Community Allocation just awarded  Dedicated 4 nodes on Mercury  Results from first 30 days (next slide) – Gaussian jobs running in restricted shell  Changing reservation to 1 node based on results, will continue to monitor usage

TG Quarterly Meeting Breckenridge, CO Apr 11, 2007 CSE Online Utilization Dedicated 4 nodes initially, now one node Goal: improved turnaround for a large number of small jobs submitted through the gateway.

TG Quarterly Meeting Breckenridge, CO Apr 11, 2007 LEAD Science Gateway  Supported Spring Weather Challenge ( forecasting contest for undergraduate atmospheric science studentswww.wxchallenge.com  Feb 19-26: daily testing, 80 processors, 12pm-5pm  Feb 26-April 27th: 160 processors; 12pm-5pm Monday through Thursday.  Actual contest submissions started week of March 26

TG Quarterly Meeting Breckenridge, CO Apr 11, 2007 LEAD Gateway Statistics  250 jobs per week, consuming 1800 SUs/week  Each workflow is 5 jobs –  250 jobs corresponds to 50 workflows  Expect this to increase once issues are resolved/reliability improves  LEAD Gateway typically the most or 2 nd most active gateway in terms of resources used  (BIRN or GridChem are often ahead)

TG Quarterly Meeting Breckenridge, CO Apr 11, 2007 Issues Uncovered by both Science Gateways  Remote job submission – great when jobs run – hard to know problems – even simple things such as planned downtime  Reservation Issues – can’t overflow end of reservation when many jobs stack up (LEAD)  If user assigns an obsolete project, don’t get useful error message back  GridFTP striped server – one fails, all fail

TG Quarterly Meeting Breckenridge, CO Apr 11, 2007 SG Next Steps  Meetings with teams to understand usage modes and issues  CSE Online NCSA contingent visiting CSE Online group at Univ of Utah Apr 23 – 25  LEAD NCSA and IU RP’s setting up a date to visit LEAD group at IU
