This is version 4. It is not the current version, and thus it cannot be edited.
[Back to current version]   [Restore this version]


June 13, 2007
Participants: Jones, Barseghian, Gallagher, Potter, Altintas, Cornillon

Developer update

  • Nathan finished actor that reads opendap data, all data in one complex data type
    • memory problems with even a moderate opendap dataset
    • need to focus on the optimizations now -- matrix optimizations needed (e.g., for 2d array of int, long, double)
    • probably 2 new types needed in Kepler
      • Grid type
      • N-dimensional arrays with optimized storage
    • next step to change actor to add dynamic ports based on the type, so that the ports can reflect the structure of the source
  • Ilkay
    • Matlab actor, using the code from Zhang at the workshop
    • Still really need Matlab actor to be as robust as the R actor
      • Ilkay will write up a list of Matlab actor issues and requirements
        • Only supports passing input variables -- need output too
        • graphical output needed too
        • issue with Matlab being local or remote (command line versus ssh)
        • should we support octave? probably a good idea
  • Derik
    • hardware for the terrestrial use case -- setup a few days
    • CR Basic code to write to PC will take a bit
    • then move on to CR Basic to RBNB -- not sure if there is existing code for this -- need to search

Workshop debrief

    • Ocean usecases
