8. Open Science Grid All Hands Meeting, Chicago IL, March 8-11, 2010 8 Summary of experience so far Initial setup was (mostly) smooth – already several years experience with condor, dcache, globus AaA. Gluex use so far: 20,000 hr (two users) – support for first user was intensive, user wrote a how-to for Gluex wiki. Some hardware upgraded – bottlenecks seen. Major difficulty with running jobs from other VO’s – how does a site administrator evaluate success of outside jobs? Helpful support from OSG central – weekly conference call (collective VO’s) – GOC ticket system – campfire chat http://wiki.gluex.org/index.php/HOWTO_get_your_jobs_to_run_on_the_Grid

9. Open Science Grid All Hands Meeting, Chicago IL, March 8-11, 2010 9 What’s next for Gluex VO? Chose a OSG-wide job submission solution Develop a suite of basic test jobs that validate sites against the Gluex software stack – very dynamic at this stage! Learn how to run MPI and CUDA applications on OSG Design workflow solution for PWA Investigate Hadoop Increase user base within Gluex Add new Gluex sites, as demand increases Increase awareness of OSG at Jefferson Lab
