| Date | Event |
| 28-Jan-2000 | Processing of year 2000 data starts, card file revision 3.39 |
| Noscell00.list copied | |
| Some jobs stop with "Candidate not in eselprobrank" in eem.fpp | |
| 31-Jan-2000 | Update in eem.fpp cures "eselprobrank" problem. |
| 3-Feb-2000 | Messages from MFUNPK appear: "FLTN/LFLTN mismatch"
Expert notified |
| New masks for failed FTD cells included. Card file revision 3.40, active
from
run 35080. |
|
| 4-Feb-2000 | MFUNPK problem has vanished, attributed to a "temporary acquisition
problem" by expert. |
| 7-Feb-2000 | Tobias fixes Lumi GAFs by remote diagnotics from Padova, at least
for runs
35091 and 35099 |
| 8-Feb-2000 | BPC South removed during shutdown. Next (DAQ) run 35178. |
| 10-Feb-2000 | Block of ZES variables (Dch_pt, Dch_eta, ...) found to be absent in
new
ZES ntuples. Experts are on CHEP in Padova. |
| 11-Feb-2000 | Processing halted. |
| 13-Feb-2000 | ZES ntuples bug fixed (zephyr/src/zes/zesbktpl.fpp) fixed. |
| Switched on generation of PMSTAT files. | |
| 14-Feb-2000 | Processing resumes with run 35125. The output files are now called
RDST2,
MDST2, NTUP2, ... Runs before 35125 have to be reprocessed later. |
| 15-Feb-2000 | Runs 35105-35108 have bad CAL calibration. These runs are flagged as
"bad" for now, have to be reprocessed & flagged back later. |
| 18-Feb-2000 | "C5 vertex problem" observed. Explained by erroneous BPC timing information
after removal of the south part on 8-Feb. |
| 23-Feb-2000 | First indication of a "tape crisis". Even after intervention, only
part of the tape
contingent asked for is supplied. This appears to be due to a tender for a big amount of tapes which was initiated in November but got stuck in the administration. -> we receive only small amounts of tapes at a time. An emergency order is on the way. |
| 24-Feb-2000 | New regular statistics process, recording daily event count taken &
reconstructed. |
| 28-Feb-2000 | Updated ZEPHYR executable with "isles" fix. The number of permissible
isles has been increased to avoid job abends. Used from run 35342 onwards. |
| 28-Feb-2000 | Updated control cards, with masks for a complete layer in FTD2 &
several more
cells in FTD1 & FTD2 (release 3.41). Used from run 35342 onwards. |
| 7-Mar-2000 | Bprecon update (South part switched off) submitted to repository. Ulrich
Fricke
finds out that Bprecon version used in 1999a.1 (=1998a.2) is not the latest one. |
| 10-Mar-2000 | End of tape crisis |
| Reprocessing of run 32701 stalled because of incomplete lumi GAF | |
| LUMI327 updated. | |
| 14-Mar-2000 | Histogram file reprocessed for run 35363. |
| 16-Mar-2000 | Histogram files reprocessed for runs 35387, 35396, 35420. |
| 22-Mar-2000 | New ZEPHYR control cards file with wider cuts for DST bit 11 (revision
3.42).
Used from run 35552 onwards. |
| 27-Mar-2000 | Runs 35575, 76, 80, 82(, 83), 84, 85 are lost on the logging machine. |
| 2-Apr-2000 | Oracle clients "oruninfo" and "rutil" fail on zenith platforms. The
run database
is not updated automatically anymore. Consultation with Oracle & network experts. |
| 5-Apr-2000 | Harald Falkenberg finds & solves the problem on the database server.
Pending
updates go to run database. |
| 17-Apr-2000 | BPC timing correction removed in ccrecon. New executable linked with
2000a release, used from run 35923 onwards. |
| Cell area in RTD (Layer 12,cells 100-107) masked in modified card input
file
(revision 3.43), used from run 35923 onwards. |
|
| 26-Apr-2000 | Deletion of runs 35575, 76, 80, 82(, 83), 84, 85 from ep_runs requested. |
| 27-Apr-2000 | During reconstruction, O(2 events per run) are unreadable due to bad
ZEBRA
records eg in runs 35981-82. Possibly EVB problem. Informed U. Behrens. |
| 28-Apr-2000 | Increased CPU time (to ~8s) for jobs in run range 36000-36030. Both
problems
vanish afterwards. According to Ulf, problem is related to bad CAL situation around Good Friday, which led to huge number of cells & high deadtime. |
| 4-May-2000 | Reconstruction interrupted because of power fail in computer center.
Farm PCs
had to be brought up manually. Still problems with AFS access on some machines afterwards. |
| 14-Jun-2000 | CTD reconstruction suffers from a modified gas mixture, which reduces
the Lorentz
angle. In the track reconstruction, the Lorentz angle is hardcoded to 45 degrees. Emergency GAFs are underway. Processing continues. |
| 19-Jun-2000 | Emergency GAFs are implemented. |
| 19-Jun-2000 | Power failure in computer center kills /recspool disk. Some monitor
files, n-tuples
etc lost. Also zephyr_dbrec card files are lost. |
| 20-Jun-2000 | Spool disks are repaired. |
| 21-Jun-2000 | zephyr_dbrec card RCS file restored. |
| 29-Jun-2000 | Lumi GAF production was found to be stuck since 4 days. Data processing
stalled.
This is during the collaboration week in Toronto. |
| 4-Jul-2000 | Lumi GAF problem was traced to a hanging calilu process on the logger
machine.
Production of Lumi GAFs takes ~1 day to catch up. |
| 25-Jul-2000 | H. Schnurbusch/I. Brock find RTD hole in layer 12 which should have
been masked.
in rev 3.43. It turns out that rev 3.43 of card file was incorrectly restored. File corrected and stored as revision 3.44. Reconstruction with card file revision 3.44 starts with run 37197. |
| 24-Aug-2000 | Datataking completed, last run 37715. |
| 6-Sep-2000 | CAL calibration for last runs complete. |
| 10-Sep-2000 | Processing of shifted vertex runs 37587-37639 completed. |
| 11-Sep-2000 | Last run of year 2000 processed. |
| 15-Sep-2000 | Reprocessing of early 2000 runs 35031-35121 finished, output RDST2/MDST2. |
| 23-Sep-2000 | Fix of DST bits in the run range 35179 - 35920 is starting. This is
done on MDST
basis. First use of new reconstruction farm & RAID disks. |
