  1. Higgs • No results yet. • I spend an integrated 4 days on this, and here is what I found out: • Donatella Cavalli pointed me to: • http://atlfarm003.mi.infn.it/~negri/dataset.htm Done To be done Ev per file Ev done • rome.004307.digit.H7_115_tautaul 100 0 50 5000 rome.004307.recov10.H7_115_tautaul 97 3 49 4753 rome.004307.simul.H7_115_tautaul 100 0 50 5000 • rome.004315.digit.H15_130_tautaul 97 0 50 4850 rome.004315.recov10.H15_130_tautaul 0 39 49 0 rome.004315.simul.H15_130_tautaul 98 2 50 4900

  2. Talked to Amir Farbin about this: • We can wait • We can run reconstruction on the U. Chicago machines – decided to do that. More help from Amir: • Samples not in the obvious place on CERN castor. • Only in Europe, and he could not get DQ to work • Alternative – use gridftp, but: • I got an invalid permission error for that certificate. • Maybe I can get help with this today.

  3. The other thing I tried was to follow Iacopo’s tutorial and generate Pythia Higgs plus fast simulation. • Started by checking out RecExCommon • Up to page 15 all worked fine, compilation and all. • However, I could not get athena to run: • DllClassManager ERROR Could not load module AtRndmGenSvc • DllClassManager ERROR System Error: libAtRndmGenSvc.so: cannot open shared object file: No such file or directory

  4. Hopefully, with some help, we’ll move the chains in the next several days. • Will pursue both directions (atlfast and reconstruction), if possible. • No results, but we’re learning… • Thanks to Amir and Erik for the help.
