  • Toni
    • Extensions - requirements are training
    • perspective - web interface is not general enough
    • GPU Grid's Soap interface is general enough
  • David
    • User Defined in this discussion is the Scientist
    • Different categories of users
    • Envisage a context where random volunteers can submit
    • Need to control the scripts where users can inject viruses
  • Toni
    • Users should not have ability to upload applications - this is a security risk
    • Applications that accept scripts should be tightly restricted
  • Christian
    • Extend template files w/ additional text.
    • Soap can be used for a web page where scientist selects for application to submit
    • Scientist must provide a template
  • Toni
    • Webpage for submitting:
      1. Does not lend itself to batches
      2. Output would not be able to retrieve on webpage
  • Christian
    • Suggested a structure where input is packed in an archive, uploaded to the server, uncompressed and used by job creation script
  • Zoltan
    • Change Execution soap website
    • Client executes application
    • Master feeds the work
  • Toni
    • Described how GPUGrid accounts for the priority of workunits. High priority starves the lower priority
    • Will release the Perl code
    • Does not deal w/ scheduler code
    • One should have a scientist's table that tracks various project scientist information relevant to submissions
  • David
    • Many options [for scientist's table], eg accounting, controlling latency, throughput
  • Toni
    • Not many scientists on GPU grid currently
  • Micheal Weber
    • Leiden Classical has a drop-down menu
    • submissions interface w/ limited characters
    • Registers the heavy users
  • David
    • Is Leiden a generic solution?
  • Christian
    • Leiden uses a separate configuration file
  • Toni
    • Computes the has of the file, avoid copying files, conserve space, use hard links in the download directory
  • Kevin
    • There should be a common mechanism to submit
  • Zoltan
    • How to submit work remotely
  • David
    • It would be good to have a standardized way
  • Toni
    • Use MD5 checksum on the input files, store the hashes on the server
  • Jack
    • What if there were a script to generate the templates, where user is prompted for various parameters?
  • David
    • Not the bottleneck for scientists
    • Need to move the WU Generator and Assimilator off the server
    • Keep the things we trust stay on the server
