Notes:

1. Core summaries: Status, Needs and Outlooks
   • OCN:
     • Still testing GM and KPP for next release
     • Pools are implemented
       • Pools provide a 10-15% speedup relative to pre-pools implementation
       • Simulations after pools are bit-identical to pre-pools implementation
   • ATM:
     • Working on rewriting loops for bit-reproducible results
     • Would like to have streams attached to variables
     • Interested in splitting up registry files
   • LandIce:
     • Implemented pools
   • CICE:
     • Pools implemented
     • Advection has been implemented
2. Release 3.0 Action Items:
   • Status of Pools in framework and cores
     • Land Ice, CICE, Ocean, SW cores converted to pools
     • ATM Cores are in the process of conversion
   • Status of multiple streams design document
     • Behind schedule
     • Depends strongly on pools for implementation
     • Could move forward with requirements, but cannot work on implementation
   • Outlook for release freeze
     • Will revisit after pools are implemented in ATM core
     • On hold currently, until pools and multiple streams are implemented
3. Other items:
   • Workflow relative to ACME
     • Discuss possible workflows and issues on the May 19th low level telecon
   • Improvements in Framework / Cores
     • Paraview catalyst could be an example of this

Action Items:

• Pools in ATM core -- Included squashing commits to fix all cores
• Discuss workflows on 19th
• Work on design for multiple streams at build time
  • Michael will put together a straw-man and facilitate the compilation of requirements and design for multiple streams.

Next high level telecon: June 2nd 3:00pm
