Minutes of the LIM meeting, Dec 09, 2004

Present: Emil Obreshkov (ATLAS), Florence Ranjard (LHCb), Eric Poinsignon (SPI), Andreas Pfeiffer (SPI)

Apologies: David Quarrie (ATLAS), Shahzad Muzaffar (CMS)

Actions:


Atlas needs the build of the latest releases also for rh73_gcc32. Andreas had the (wrong) impression that this platform was used only for production in Atlas, not for main development, that's why the releases were not build for this platform. The builds will be started this week.

Markus has asked for SEAL 1.5.3 to be also build on windows, this has started, but so far the environment is not yet set up for Andreas to have a successful build. The instructions on the SEAL web page assume a certain environment present, but do not provide a procedure on how to set this up. Andreas is working on this and documenting it.

Issues:


To be able to fix potential problems with the re-built slc3 packages, the main changeover is now planned for early Jan (first week, certainly before the lxplus alias is changed to be slc3). This also requires some changes in the projects infrastructure (config files). The test version will be made available to the Librarians early next week at latest.

LHCb requests the configuration as described in LCGCMT_26_2d (not available in SCRAM !?) for the SLC3 port (plus the latest releases based on LCG 31(b)). Also the _dbg versions for the projects' s/w based on LCGCMT_26_2d are required. Andreas will build them asap.

Florence asked the "special build" of root (3.10.02_0411 to fix a problem which LHCb had observed) to be renamed as 3.10.02. Eric will do a diff and see which changes there are between the two releases. If there is no differences (apart from dates of build) we can do the renaming (although it would then be strange why identical s/w behaves differently), otherwise we have to escalate this to the AF.

Next meeting: January 13, 11:00.


Action items:

new and outstanding:

- provide _dbg versions for SLC3 platform - re-opened as LHCb needs the versions of LCGCMT_26_2d

- check status of root-4 based releases - seal 1.5.3 based on root 4.01.04a build for rh73_gcc323 and slc3 (incl. _dbg).


closed:

- plan/install external packages for CMS and LHCb - installed for the CMS req. packages on rh73_gcc323 - porting to SLC3 will start soon - problem with callgrind: to be investigated by Eric with Stefan Roiser.

- plan for releases on Mac - problem on Mac (see minutes of Nov 11, 2004)

- provide _dbg versions for SLC3 platform - foreseen for the new releases of the projects: seal 1.4.2, pool 1.8.0, pi 1.2.4 and the root-4 based counterparts. -> (11nov2004) closed with the cutting of the mentioned releases.

- PI 1.2.3 for rh73_gcc32 - moved to version 1.2.4 (using seal 1.4.2) -> (11nov2004) done with release 1.2.4
