Meeting Notes for 12 May 2010

Common

• www14 fell over, MCS powercycled it
• End of schoolyear, in June there are a bunch of workshops

Cosmic

• TomJ working on splitting possibly-corrupt data
  • Add a comment in the metadata (e.g. "This file was reprocessed on $DATE to address a postprocessing issue").
• Upload issues
  • Fix deployed last weekend - we now write directly to NFS and rename rather than write to local storage and copy
• Analysis issues
  • Tomcat ran out of RAM - possible leak? We'll take a look when we can.
  • Get a stack/heap dump next time
  • Run a quick performance study every couple hours and email on failure?
• Helpdesk form issues
  • Should get a real trouble ticket system (Bugzilla, Trac, OSTicket, RT)

LIGO

• Tutorial needs to be written for Super-Bluestone
• Screencast?

CMS

• Screencasts to demonstrate events (e.g. LEP events for the masterclass.)
  • Show iSpy, Fireworks or Frog displays? Some sort of JavaScript selection?
  • 10-12 images, start with LEP then move to CMS. Let users get their feet wet.
• Need to get Mihael's UI working with the ROOT backend.
  • The addition of signals in OGRE is nontrivial? DanK is working on it
    • Is this an issue for the people generating the MC data for us?
  • Trivial to split MC files? ROOT's data files are binary blogs - what does Doug mean?
    • Doug is referring to the config files that builds the ROOT files.
    • ROOT output? Another format?
  • Doug uses iEvent or CMSSW to generate files
  • From a science standpoint, randomly mix data (it'd look more like real data)
• TomJ and DanK met with RandyR and KenC
  • Randy surprised about any 3D requirement
  • Still looking at tools/a solution to generate these images
  • Contact George @ Northeastern
• Milestones - in progress/development
