AF meeting 13th September 2012
News from Projects
- Cling development for ROOT 6 is on schedule
- Although not asked for yet by the experiments, we'll make next week
patch release v5-34-02 as there are enough fixes to warrant a release.
- And last be certainly not least, we finally will revive the popular
series of ROOT User's Workshops where the last one has been held in
2007 at CERN. The new workshop is planned to be held in
Saas Fee from 11-14 March 2013. Would be really nice if the
experiments won't plan their software weeks in that week ;-).
- Released 64a yesterday, including bug fixes to externals; no new LCG
- No news yet on the Mac service in IT. Apparently the person working
on it was ill and the progress was slower than expected.
- A while ago we had a discussion in the AF that the move to C++11 and
gcc47 unfortunately are coupled - due to binary incompatibilities
between C++11 and C++0x. In the meantime the problem has been
addressed. The future versions of gcc 47X will make C++11 and C++03
compiled code binary compatible again. Once the official gcc version
with the fix is out, we can start the migration of LCG releases to
- Work is ongoing on CORAL monitoring, mainly to address some feature
requests from CMS.
Few points for the Simulation from the Geant4 Collaboration meeting in
- The schedule for release 9.6 of Geant4 is confirmed and release date
is fixed to November 30th, with first candidate code availble starting
from beginning of November.
- Release 9.6 will be the last release of the 9 series.
- The release in 2013 will be a major release which will also include
multi-threading cabability for event-level parallelism. Received
requests from ATLAS and CMS for 'on-demand' simulation compatible with
their chosen concurrency model, requiring further investigation.
- The latest development release 9.5.ref08 was made available last
week; installation is available on AFS as usual, now using packaging
- The next Geant4 Collaboration meeting will take place in September
next year in Sevilla, Spain.
- CMS selected Intel TBB as foundation for it's future multi-threaded
- Work continues on factoring REFLEX API usage in self contained parts
to ease the migration once ROOT provides an alternative API (if not
- We will build the next development software stack on top of LCGCMT
64a (mainly for the SLC6 support).
- We are waiting for the instructions to replace Reflex.
- We do progress on SLC6/gcc46 builds - and should be done very soon.
