II. GSI Regression Test Suite Based on JME scripts (ksh, perl) Currently includes 6 test cases (4 from EMC), easy to extend Cases selected through configure file Verify all test cases and then produce a summary Will include full capability of the EMC’s GSI regression tests. Works well on NCAR IBM (bluefire) - porting to Linux 6

V. Collaborative Efforts 10 Short-term: tutorial (we already work together on the planning) 2.Users' guide (we got corrections and comments on the first draft from Russ and Wan-shu, through John) 3.Code management plan (John agreed to review it) Long-term: 1.GSI Scientific committees EMC-GMAO committee? (include Boulder members or observers) Boulder GSI committee (need a member from EMC) 2.A common development plan 3.Share information on GSI development wiki Regular developer meetings GSI workshops and tutorials Regular updates, at least with new releases, for the users’ guide (need a member from EMC)
