RECO Status Report June 3, 2002

Current official production version: p10.15.02 Latest production version: p11.08.00 p11.07.00 was scheduled to become the official production version on May 21, 2002. This milestone was not met. Two major problems contributed to not meeting the milestone: 1) a bug in the calorimeter non-linearity correction software causing all calorimeter clusters to have invalid energies, 2) incomplete testing and documentation of RECO. The calorimeter NLC bug was fixed in the final p11.07.00 build, and we are currently running p11.07.00 on the farms processing various test samples. So far, the performance looks as expected. However, there appear to be more crashes in RECO / RECO_ANALYZE than in p10. These are being investigated and patches are being applied in p11.08.00.

p11.08.00 is scheduled to finish on June 5. (Since there are two power outages scheduled for this week, the exact date is a little uncertain.) p11.08.00 contains a few bug fixes (e.g. floating point exception fixes).

Algorithms and Object ID groups are in the process of documenting and signing off on p11. It should be available for deployment to the farms by the end of the week.

Plans for p12 are being discussed now. Each Algorithms and ID group has been asked to supply a list of goals for p12. In addition, a list of specific tasks to accomplish those goals, the personnel assigned to those tasks, their level of effort available (%FTE) and when the tasks should be completed is being compiled. This exercise will be done for p13 as well. The current RECO schedule is

• July 29, 2002 – p12 installed on farms
• October 28, 2002 – p13 installed on farms

It is hoped that with the development of a task-oriented schedule, RECO milestones will be more reliably met. Harry
