Minutes
Attendance: Brian Warren Jolien Patrick Ed Kent Stuart Duncan Greg Ben Adam Peter Igor Keith Shourov Patrick requested that people would respond to the e-mail he sent around last week. Ben mentioned that Shourov appears to have found a data corruption issue. Some data being repeated ~1/16 sec of repeated data from time to time. Only found it so far in FB1 data. As many as a hundred channels might be affected. Many of these channels were only added recently at LLO. Greg mentioned that if we switch everything to FB0, it will fall over. CDS will have to work on this. Rolf is the head guy. Alex will be the person at the LSC meeting. Has gone up the food chain already. Vern knows about it. Dave Barker. Ben and Keith are looking into it. On that side of things, they don't look at frames. Shourov is looking into it. Ben is saving frames from both framebuilders. This came up from the output of the S5 search; Duncan noticed this thing that he passed it on to Shourov. It is exactly on the 1/16 second boundary, so it is easy to diagnose. Shourov is working on the problem. Ben has been checking what is happening at LLO. Looking at the CRC checksums, LLO does not show this problem since last Friday. Ben's scripts have identified the times. Shourov is checking which frame-builder has the problem. This information will get to Keith Riles and to Vern Sandberg. There were no urgent reports from the project Librarians. Duncan reported on the SegFind server/client that he developed and that Igor is going to take over the maintenance of. His presentation is at http://www.......... Warren asked about the licensing. It is available under the IBM scholars program. It is linked from the segfind documentation site. Duncan thinks this license is available in all of the countries we're interested in for academic use. Duncan also linke something else in the web site with information about the QReplication.
