2. 100K Test Status: migrate
Simona ran on 12 files on the ILC machines
Built own ProductionExe
I ran on 22 files on Wisconsin machines
Build own ProductionExe on SL4, default on SL5
Compared results of default vs mine on one file on SL5
PAD files same size
Stntuple files different sizes (?)
Histograms bin-wise identical
Comparison br042ecb.03b7phys histo files
SL5 hers vs mine: identical
SL4 hers vs mine: identical
SL3 hers vs mine: not identical, bin shift

3. 100K Test Status: migrate
Ray compared 2.2M SL3/SL4 vs SL4/SL4 Build/Run of ProductionExe
Most not identical
Pass KM test at 5 9’s
My comparisons found
Half files not identical
Almost all histos pass KM test at 8 9’s
Simona’s comparisons (subset of mine, we mostly agree)
Most identical
Handful fail to pass at 6 9’s

4. Details of a Difference
31-Mar-2010

5. Comparing plots directly
Bin shifts
This passes KM test at 8 9’s

6. Another difference
LumMon/event_1

Bin shifts

7. Bottom Line Can you spot the difference? Almost every histogram
difference is invisible.

8. Proposal If we agree that
6.1.4mc.migrate deemed satisfactory
6.1.6.migrate results deemed satisfactory
Create 6.1.4m.m, m, m releases for announcement on Monday
If we want a 1M SL5 run, can we have that by Monday and schedule a phone meeting?

9. The future
Terminal Release
OS migration
Maintenance
31-Mar-2010

10. Terminal Release: Contains
Xrootd support
New root: Series 4 or 5? (5 is ambitious)
Some reworking of Event display
64-bit addressing
Joint Production/MonteCarlo release
New tracking available as option
Fixes required by physics groups
New MC engines?
Rest of list: me with other items
31-Mar-2010

11. Terminal Release: Target
CDF to take data for no more than 3 more years
Declining manpower already
Mature analyses: not eager to revalidate on new releases
No software changes likely after data taking stops
If we want terminal release to be used, probably no later than 1 year from now
better if this year.
31-Mar-2010

12. Future OS Migration 3 years + N-year trailing off of analyses
Probably at least one more OS update on the farms
How hard will new migration be?
Lynn has modernized the tools: (month less)
Bugs in compiler are wild card
Monte carlo validation is tricky
Need physics group volunteers earlier
Maybe 2 months or less?
