The Change Review Board Process• Gather community and stakeholder input
◦ Special joint CRB/JST telecon prior to each CRB meeting◦ Ad-hoc consultation by CRB members with their respective communities
and stakeholders• Meet quarterly to review and update the development schedule
◦ Review and approve (sometimes with adjustments) the next internal release
◦ Review community inputs, and add development tasks to the schedule based on this input
◦ Adjust the future release schedule based on current realities and changing priorities
• Publish the updated schedule on the ESMF CRB web page◦ http://www.esmf.ucar.edu/plans/releases/sched_current.shtml◦ Or Navigate from the ESMF main page via the “Release Schedule” Quick

• Members are appointed by the ESMF Execute Board to 1 year renewable terms
• Members represent the user community, not just their own institutions or agencies
How’s It Working?• CRB continues to meet quarterly (mostly via telecon)
◦ Approved 2 Internal Releases (v3.1.0, v3.1.1) and 1 Public Release (v3.1.0r)
◦ Development focus this past year has been on moving ESMF to the new Array and Grid structures, array and grid redistribution capabilities, implementing and testing the new sparse matrix multiply functionality, and performance optimization. These are all now in the Public Release v3.1.0r.
◦ The new internal structures, along with the sparse matrix multiply, are key to ESMF support for Regridding.
Planning For 2010• ESMF has committed to a stable API (with backward compatibility) in
2010• This past August, the CRB held an extended meeting to look at
development priorities and a schedule for meeting this commitment◦ Focus is on completing remaining high priority functionality
development that would have an impact on the ESMF API◦ High priority items identified are:
• User-method Callbacks for data assimilation• Conservative regridding• Multi-tile grid representations• Land-sea masks for regridding• An I/O implementation
Planning For 2010 (cont)• The CRB’s highest priority is to assure that development which has an
impact on the ESMF API is completed and delivered in Public Release v5.0.0r. This release has been tentatively scheduled for April 2010.
• The development schedule has been fleshed out to the Apr 2010 Public Release. The schedule was developed with larger than normal margin so that the stable API commitment in 2010 can be achieved.
• After May 2009, the backlog in the feature request log will be cleared out in the context of the v4.0 functionality◦ Some feature requests may be closed out as obsolete or as
subsumed under existing functionality• Six Months is reserved before the end of FY10 to clean up
documentation and update tutorial materials
