<noautolink> ---+!! LHCb Core Software Meeting ---++!! Date and Location [[INDICO:247334][08-May-2013]]%BR% 10:30 - 11:25 %BR% CERN (2-R-030) %BR% ---++!! Attendees Ben Couturier, Joel Closier, Liang Sun, Marco Cattaneo, Marco Clemencic (minutes), Markus Frank, Stefan Lohn ---++!! Subjects %TOC% ---+ News * Switch of the lxplus alias to SLC6 * lxplus(6) reported to be very slow * [[https://its.cern.ch/jira/browse/LBCORE-128][LBCORE-128]] * problem with the configuration (e.g. CASTOR) * Markus does have problems with the login scripts * LIM * LCGCMT 65 not yet released... (ROOT 5.34.07 might be included) * Discussion on a new versioning scheme for the externals (simplify and remove the "_python26" type of extensions) (see [[https://its.cern.ch/jira/browse/LBCORE-120][LBCORE-120]]) * new interface dcap ---+ Issues in JIRA * [[https://its.cern.ch/jira/issues/?filter=10913][for the meeting]] ---+ Round Table ---++ Marco Cl. * Nightly Builds: waiting for lxbuild119 * Ben: we do not need anything anymore for installing on CVMFS, because we will use a virtual machine for it * Joel: still a problem with the server HTTPS certificate * investigating the possibility of a database backed implementation of the dashboard (AKA summary page) * Migration to JIRA ([[https://its.cern.ch/jira/browse/LBCORE-120][LBCORE-120]]) * Victor is currently busy, so we have to wait a bit * we will start testing with Gaudi, LBCORE and CondDB, followed by LHCb Deployment * Implementation of the replacement for SetupProject for CMake ([[https://its.cern.ch/jira/browse/LBCORE-12][LBCORE-12]]) * 2 new tools: =lb-run= and =lb-dev= * one more tool to come: =lb-setup= * some fundamental differences between the new tools and SetupProject, some can be removed, some not (see the comments and the worklog in [[https://its.cern.ch/jira/browse/LBCORE-12][LBCORE-12]]) * The code to access the compressed DB has been released with the latest LHCb. Now I reorganized the code so that it lives in one single library and and I will prepare builds of that library for all the versions of LHCb used in productions, to be added to the environment via Compat. ---++ Stefan * Working on the improvement of the visualization in LHCbPR ([[https://its.cern.ch/jira/browse/LBCORE-72][LBCORE-72]]) ---++ Ben * Several support requests following the SLC6 switch * Discussing the deployment of HEPOSLib RPM: we should not ask to have it on SLC5, better to switch to SLC6 * volhcb34 moved to SLC6: improvements in the performances (~5%) * Working on the implementation of the SoftConfDB in Neo4J ---++ Joel * Put in production the new LHCbDirac * Try to keep the control of the versions of the middleware (now they have a good RSS feed). * Opened a ticked because =/cvmfs/grid.cern.ch= does not work on SLC6 (not up to date? for sure not in sync with AFS). * Installed a new package on volhcb34 to play with CPU frequency * Start to evaluate some FAQ software to be shared between LHCb and Dirac. ---++ Liang * Testing improvements of performances switching from double to float (preserving correctness). ---- </noautolink> -- Main.MarcoClemencic - 08-May-2013
