Session 0

18 Nov 2008

Question 1: You are planning to start analysis, where would you go to look for information

  1. starts in
  2. goes to from the left bar
  3. looks under documents and information title
  4. clicks on CMS wiki (does not work)
  5. looks for practical info with examples
  6. looks under title User support
  7. goes to
    1. suggests the page to be called CMS tutorials on physics analysis
    2. notes PAT and thinks it should be interesting
    3. reads the contents of the data ana flow tutorials entry
  8. goes to
  9. follows the indico link to prompt data session
    1. is note sure if this is the page but will have a look
    2. open slides of What data do we get: Triggers
    3. goes through slides quickly, thinks interesting but not what he was looking for
    4. has a general looks and thinks it is nice but goes back
  10. looks and reflects the session names and decides to go to Session 4: T2 and analysis
    1. reads the titles and thinks this is OK
    2. goes to Tier2 data and analysis model slides
      1. looks through and understands that being at CERN can work at t0/t1
      2. find that t2 is for analysis (slise 2)
      3. is not sure is CAF is a t2
      4. is looking for info on using t2 for analysis but the slides speak about caf (thinks that in italy he would use t2)
      5. thinks (being at slide 4) that caf is the place to work and castor to store data, wants to know how to access caf
      6. sees title user space (p 7) and want to know how to use it
      7. wonders what VOMS is about (slides 8)
      8. watches the sl 9 figure on analysis workflow and understands that CRAB provides the intreface to computing resources
      9. likes the phrase "How does it impact you" on slide 12 as looking for info how to get working
    3. goes back to and says normally browses over slide to get an overviw
    4. says that title How to find and store your data is good and goes to slides
      1. thinks that this give a good summary of the slides above
      2. say good to have an example on p 6
      3. sees dbs and tried it once, would be nice to have a description linked and thinks would open a page (not in the slides) thinks doing it later
      4. says p 10 quality is not good (screen-shot)
      5. in general, thinks that these are the technicalities to know in order to reach the data but does not know how much he should suffer before reaching the data
      6. thinks that after dbs needs to learn using crab
    5. goes back to agenda and PAT slide
      1. asks what is AOD
      2. remembers to correspondence with delphi data, first everyone looked to raw data then DST data (common tools, lighter)
      3. reads through pat slides
      4. expects that pat will give different classes of muons (according to quality etc)
      5. on slide 8 says looks promising
      6. comments that plenty of twiki pages as usual
      7. comes to PAT tutorial and says that when he would go back to his computer and would follow this tutorial
      8. says that it is important to have a first working example which he can then try modifying

Question 2: Your analysis will include muons, find information what the muon physics object contains

  1. starts in
  2. goes to physics
  3. goes to
    1. reads contents, find Documentation in the end and goes to
    2. read about the basics and says gives links to different classes of muons but does not find a link to the muon
    3. looks for keywords i.e. which classes should be used, and what are the properties of the muons
    4. gets the hint the information is in the data format of the muon 1 goes to
    5. browses through the page
    6. gets a hint that he finds the information clicking on the name

Question 3: You would like to know what other people have done

  1. starts in
  2. goes to physics
  3. goes to Higgs PAG
  4. finds the information on the working groups
  5. thinks of looking at the anylsis notes but for more recent information would look in indico presentations
  6. asked if you would expect to find code examples
  7. goes under the title ongoing anaylsis
  8. goes to
  9. follows
    1. think that a common tools to do this would be very useful and thinks of finding it talking to people
