Lehman Review:
Wednesday and Thursday. SAS presentation is 10 AM (PST) Thursday,
just before the summary.
-
Core issues and status: (Toby) See
Toby's
run-down of issues of interest
here
and follow-up on some of them below.
-
Turning back the clock: (Leon) Part of the chi-square adventure has
been an effort to reproduce and understand the results of summer, 2002. This
is now, after considerable effort, about ready to go. Stumbling blocks along
the way included: apppropriate GlastRelease version had changed repository
address, needed to build old version of cmt but couldn't (saved by Heather,
who had a built version lying around),...
- RootTreeAnalysis macro: (Matt) He
is recrafting it to be more modular and flexible, a plus for both interactive
users and System Tests. The new version will use modern constructs unavailable
when it was first written. A new DataManager class is a principal player in this
design.
-
Flight Integration: (Richard) The
weekly run-down:
- Opus: (Dan) Alex is about to release a wrapper script for stored
procedures. Dan has finished writing major procedures; a couple lesser ones
still to go. He spoke with Neil Adams, SLAC LSF administrator, on how to
monitor LSF jobs. Currently polling is all that's available. Neil will
contact LSF people about implementing a better mechanism (e.g. event driven
from the LSF side). Also Dan will be talking with Babar folk to learn from
their experience. (Matt) Web interface, not yet in final form, is working on
his laptop. Requires another iteration or two; should be available late this
week or early next week.
- Timing tests: (Richard, Heather) Heather assembled a suitable
collection of optimized libraries and code and ran some tests. One (the?)
goal of this exercise is to get a feeling for how many boxes will be needed
to support a stand-alone LAT somewhere other than SLAC. The old estimate of
about 75 can perhaps be lowered to more like 30, still a significant
investment.
- EBF news: (Heather)
- There is a new Online library; yet another, newer one is expected soon
with ACD-related enhancements.
- The new package, EbfEvent, split off from EbfConverter, has taken care
of build problems seen last week in packages using RootIo.
- In the near future there will be a spate of package renaming to
replace EBF with LDF (LAT
Data Format)
- ACD calibration support: (Heather) She and Xin will start working
on it.
- Calibration database interface: (Joanne) Discovered that
our version of MySQL (3.23, pretty old) doesn't have all the features I was
coding against in the new rdbModel. Alex is agreeable to upgrading the server to 4.1; we don't
expect this to cause noticeable disruption.
- Document effect of MC pruning options (Riccardo) (8/5/2003) It's
documented in the code; Tracy will look into putting the information in a
more accessible place. (9/2/2003)
- Write up, and perhaps present at a future meeting, hints on debugging.
(02/18/03) Some combination of Toby and Tracy will provide
something for Windows.(7/22/03)
- Overhaul documentation altogether by about November (Heather and ??) (9/2/2003)
In progress; not yet done (01/13/04)
- Resolve calibration/timestamp issue. (11/20/02) Online folk have not yet thought about
putting timestamp information into EM data, but, thanks to Richard's
inquiry, may now do so. (2/25/03) We can probably live without a realistic
system for EM, but we will put it on the agenda for the DC1
workshop.(5/6/03) At the DC1 Workshop Steve Ritz promised to find an
authoritative reference for timestamp format and pass it on. (7/17/03) Now
that events have "real" timestamps, Joanne needs to reassess
situation with Calibration (9/2/2003) Timestamp exists in EM data. Needs to
be fetched by Calibration (1/13/04)
Put on hold until formats settle down. (3/16/04)
