WorkShop09_ScientistUsability

• 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 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
