Generator issues

Issues from the meeting 12 Dec and mails afterward.

(1) Crossing angle:
  No crossing angle at generator.  Should be boosted in Mokka/SLIC
 
(2) Size of stdhep file.
  limit at 500 MB.
  
(3) GRID directory
    /grid/ilc/prod/ilc/mc-dbd/generated
    /grid/ilc/prod/ilc/mc-dbd/ild
    /grid/ilc/prod/ilc/mc-dbd/sid
    /grid/ilc/prod/ilc/mc-dbd.log/generated
    /grid/ilc/prod/ilc/mc-dbd.log/ild
    /grid/ilc/prod/ilc/mc-dbd.log/sid
    
   A proposal by A.M. in generated directory, ( to be discussed )
   create the following structure.
   [ECM]-[LumiLinkerNumber]/[process-type]

   Mor eexplicitly, for 1TeV sample,
   
   .../generated/1000-18/higgs/  ( higgs samples produced by Tim )
   .../generated/1000-18/4f/     ( 4f samples produced by Mikael )
   .../generated/1000-18/tth/    ( tth, ttbb, ttz produced by AM)
   .../generated/1000-18/2f/     ( 2f samples produced by Mikael ( qqbar, mumu, tautau, ee)
   .../generated/1000-18/6f/     ( 6f samples produced by Jan )
   .../generated/1000-18/aaae/   ( aa-->ff, ae/ea->ff, aahadrons, aa-->minijets by Tim)
   .../generated/1000-18/eepairs/  ( pair files generated by Anthony )
   
   Similar directory structure should be defined for another energies.
   
(4) Question to Mikael :
  "Do we need to store job lon on GRID ?  Isn't it sufficient to store them on Web ?"
   

(5) File name convention

  Example:
  E1000-18.Pttz-ln4q-zqq.eR.pL.Gphyssim-1-02.I106336.S05.stdhep

  E[CMEnergy-LumiLinkerNumber]
  P[process description string]
  G[generator name and version number]
    physsim-v01-01
    whizard-1-95
    pythia-6-4-22  ( not use dot )
  e/p : e-/e+ polarization or photon nature
      e.g. eR80.pL30 (+80%,-30%),  eL.pR (100% polarized)
      B beam strahlung photon, W: Weizker spectrum
      eB.pR : beamstrahlung photon + positron
  I[generator process ID]
        0 to  99999 (SLAC), 1
    100000 to 199999 (KEK)
    200000 to 299999 (DESY)
    300000 to 399999 (CERN)
  S[file-sequence-number]
  

(6) whizard.prc and whizard.in
    - OPAL tune 
    - m_b =0 even not using aliasing ?
    - m_h and gamma_h for non-higgs channel
    - how to switch off gluon.  alpha_s=0 in parameter block ( whizard.in ? )
    - do we agree to use "omega w:c,c" in prc file ?

(7) Lumi-linker file.
    - Do we agree to use lumi#18 ? ( B1b with waist shift )
    
(8) Pythia error handling 
   - skip event when pythia error is detected.
   
(9) Mapping lumi-linker file number, cm energy, and beam parameter name
   http://www-jlc.kek.jp/~miyamoto/CDS/LumiLinker/LumiLinkerNumber.txt
   Is this sufficient ?
   Can Tim prepare a similar file at his site ?
   
(10) Questions to Tim from Mikael : 
 " Does the value of the sqrts variable in
  the &process_input block have any meaning when USER_spectrum_on = T in the
  &beam_input block? "
