Environmental hydrology team meeting

Environmental Hydrology Team Meeting

  • Show how the Alliance has demonstratably changed the nation’s computational infrastructure

  • Show explicitly how we have empowered communities to do things better

  • Focus on deployment of infrastructure

  • Deploy real codes to real researchers coupled with real metrics of use

  • “Harden” software to be accompanied by documentation, training, and dissemination

Primary Alliance Objectives in Year 4

Educational focus secondary for this year in AT


Purpose of workshop

Purpose of Workshop

1)  Learn about the current status of EH projects

  • Develop overall team goals for this year in light of Alliance goals

  • Refine SOW’s in light of team goals

  • Determine current and future AT and/or EH team collaboration

  • Define expected deliverables this year both dependence and independent of EH development

  • Identify what is holding us back from reaching our individual and group goals

  • Discuss communication and reporting

  • Plan group PR

  • Other ?????


Presentation guidelines

Presentation Guidelines

1)  Briefly summarize past accomplishments and deliverables with at most 3 to 4 bullets on 1 or 2 overheads2)  State your main goals and deliverables (and your groups specific contributions to these them)  for this year.  I would like at most 4 bullets here.3)  What communities will you actually impact this year and how will this be accomplished (include plans for disseminating software or interacting with communities who will benefit from your work)4)  Note who on your team will actually carry out the work and what percentage of time they will be contributing5) Note your questions/concerns about realizing the goals and deliverables (e.g., looking for a student to work on this, work can't begin until January due to other commitments, when will a linux cluster be available for me to work on,........)
