(visitor's info)
The primary goals of this work are final preparations for STAR MDC3. At present it is anticipated as a developers working session and not with formal presentations.
Attendees should contact Doug Olson (dlolson@lbl.gov) by March 7 so that access to BNL can be arranged.
status | goal | description / summary (as of 7-Apr-2000) |
done | 1 | Build index on new STAR files |
The index was build (several times) on the new STAR MDC3 data. This consisted of about 5,000 events. By the end of next week (start of MDC3) STAR expects about 140K events to put in the GC index. Sasha is continuing to accumulate additional event tag files as they are available. |
||
done | 2 | Check that GCAClient and MinimalQuery work |
Modifications to GCAClient and the MinimalQuery (& MinimalQuery1) test programs were completed for the updated version of STACS, including the new file bundle flag on the iterator. | ||
done | 3 | Run MinimalQuery on linux |
GCAClient & test program was compiled, run successfully on linux as well as Solaris. This included modifications to the Makefile to build both on linux & solaris. | ||
done | 4 | Run multiple MinimalQuery simultaneously |
Run on linux. Not verified yet on solaris. | ||
done | 5 | Test index update |
The feature of being able to update (add new events) to an existing index was justed added. This feature was first tested during this period. A number of bug fixes were made and the basic procedure is working. John is continuing to investigate one or two bugs before the procedure is declared reliable. Completed 22-Mar-2000. | ||
done | 6 | Test index update while queries are running |
This is a functionality test and was successful. Any remaining work on the udpate functionality is not related to interlocks with running queries. | ||
done | 6.1 | update between queries |
This check is to run a query before the update and then after and verify that the results are accurate. This was successful. | ||
done | 6.2 | update while new queries are being submitted |
This tests the interlock mechanism so that queries do not run during the update process. This was successful. | ||
done |
7 | Integrate GCAClient into root4star |
This is the final work to connect the GCA to STAR data analysis.
There were various discussions among Victor, Sasha, Jeff, Frank, Dave, Doug. The basic idea of how to incorporate the GCAClient into StIOMaker has been worked out by Victor, Sasha & Jeff. Sasha & Victor will work on it. Completed 7 Apr 2000 (STAR dev release). |
Alex's detailed summary of test runs, etc., from 16Mar2000. See /star/rcf/GC/MDC3/test_results/description for further updates.
