Status/Action items as of July 5, 2007:

• A MOPS document is being circulated, John to provide comments/status and post to the Wiki.
• Need to commit to a date for having MOPS 1.0 completed and available for distribution.
• GridFTP has the APIs included and is ready for integration with NeST
• Nest should be ready for integration by mid next-week. It will not have all the features but should be stable. The additional features should be complete within a couple of weeks from that time. (Nick)
• Will make plans for testing next week.
• When can we target the technology for inclusion in the VDT?

Agenda for July 19/20, 2007, MOPS discussion at Fermi (in progress)

• MOPS API working document has been posted.
• Testing has occurred with Nest & GridFTP. Need status update.
• Several errors were found & corrected in GridFTP.
• Next steps including plans for testing & target date for MOPS 1.0 release
• Any other issues that need to be discussed

• Additionally, per the last meeting and discussion we agreed that GridFTP should eventually be able to advertise itself and its state. We need to discuss what state variables are needed for a higher level scheduling service to utilize it.

Discussions at the July 19/20 meeting

(Ann, Miron, Matt, Don, Raj, John, Andrew, Rob, Nick, Mike, Dan, Ruth)

• Began the User Documentation (discussion)
  • Document to start circulating (Dan)
• Joint testing is underway
  • Nick's team has a GridFTP up and running
  • Once code is stable, a snapshot will be handed to Mike & John (July 27)
  • Goal is to have nightly & on-demand testing of LotMan GridFTP++ combo
    • Plan to integrate Metronome
• Nick's team still developing (to be completed by Aug 3)
  • Build more on ACL Plugin (error handling)
  • Finish fsck tool
  • Finish performance metrics (hoe many operations/sec it can sustain)
  • Complete API documentation
• How should we package the MOPS product?
  • Plan is to incorporate it in the Globus installer.
  • Will need to decide on a name "GridFTP-XYZ" "GridFTP ++"
• What data elements should GridFTP export
  • Trying to make a managed service that people are happy with is very difficult.
  • As a first cut, perhaps the thing to export is the status of GridFTP
    • Is it happily running?
    • Is it dropping files?
    • What is the average transfer speed?
  • We need to revisit this topic.
