Apologies: Thorsten

News

Fred: UK payment of CtC has been received by ATLAS.

Robins and ROS software

Barry+Fred: The boards with problems are back to CemGraft and will be x-rayed again, but the timescale of any outcome and feedback from them is unclear. At least the good news is that this is not a wide-spread problem. Many more Robins have been used since the last meeting (when this problem was reported) and only one had showed a problem. The production of an extra 67 boards will start soon in Germany.

Gordon: The phase-2 commissioning run has involved LAr/Tile and a few Muon chambers. Generally successful, but problems showed up and got fixed. In particular, currupted data gave rise to many error messages and this caused crushes, since ERS was not completely thread safe. Fixes went in (also from the detectors to avoid sending corrupted data) and no crushes were seen since then. Currently, a discussion is on about how to deal with requests for events that are not in the Robins. The most favourable solution currently seems to be to re-queue these requests.

Gordon+Jiri+Erkcan+etal: The next technical run will take place the week of 19th March and will focus on HLT integration. Jiri and Gordon will be heavily involved in this, Erkcan, Dmitry and John will take HLT shifts.

Farms

Fred: 1st rack of Dells installed. 3 more racks are there and will be ready to use soon, once some power distribution issues are sorted out. Finally one reack of woodcrest machines should be available by mid-april. A 2.3GHz quad-core machine is ready for delivery. It will go to RAL next week and soon after to CERN. No more CPUs till the end of the year.

Networks

Fred: Additional equipment is being ordered for the 2008 farms.

HLT Software

Dmitry+Julie: Migration to configurables of T2UK packages

Erkcan et al: problem with inefficiency in electrons traced down to differences between offline & L2 spacepoints. Using the offline space points, we recover all the efficiency losses. The problem seems to be in the code forming the SPs from clusters and evaluating their global position.

ACTION: Erkcan, Dmitry and Nikos to get to the bottom of this.

Dmitry: timing looks ok in 12.0.6 - to redo with the new BS converters.

Jiri: produced dedicated release for the technical run.

Paul+Simon: continuing work on TriggerTool. Awaiting feedback on the usability of the tool from next week's Technical run.
