ENM Pipeline Conference Call 14 Sep 2004

Participants

Jones, Zhang, Pereira, Higgins, Berkley

Discussion

  • Ricardo summary of work
    • Finishing java bindings for OM, includes JNI code
    • Looking at the ENM pipeline, thinks OM
      • replaces rescale values actor (done internally now)
      • 3 GARP actors replaced
      • 4 step postprocessing optimization algorithm replaced too as one OM actor

  • OM actors will take layers, a sampling grid, and occurrence data as inputs
    • handles all clipping an re-projecting needed
    • image outputs are currently GeoTIFF and bitmap
      • current image converter needs to be able to create lower resolution images for display
    • DIGIR query is currently a single call to DiGIR
      • Need to do a DiGIR 'inventory' call to get list of species, then iterate across those species
        • But note that EcoGrid does not provide the DiGIR inventory method
        • Also note DiGIR results are not yet handled in Kepler

  • Post processing steps are underspecified

  • Action items
    • finish up DiGIR integration (Rod)
    • Need environmental layers in ecogrid with metadata (Deana? Matt will ask her)
      • Ecogrid moves data layer files to nodes as needed by OM
    • implement post processing, mostly GIS ops along with ROC threshold (Ricardo will further specify)
      • SummaryStats -- pairwise intersections between Grid layers (current vs predicted)
    • implement OM (Ricardo)
    • GRASS routines need to be redone using JNI to better handle GRASS output (Jianting)
      • verify all GIS operations are complete
      • Clipping actor needs to gen a covex hull, check to be sure it does
      • deal with data transfer issues for GRASS web service
    • Distributed computation to apply more significant computational power across iterations (Dan)
      • use map actor to refactor pipeline for simplification of iteration cycles
      • 5 climate scenarios, 1000 species, 500 garp runs per species
      • Make sure data is available on node when OM needs it for a given iteration
        • Probably passing file-handles instead of data tokens (GDAL in OM depends on file handles)
