- Added David Lange to the AF mailing list
- Setup a common calendar (Google?) with
the most important events. (John Harvey)
Management Issues (Pere)
- Technical and Doctoral Students
assignments to SFT group:
- 1 Tech or ROOT
- 1 Doct for Simulation
- 1 Doct for CernVM
- H2020 initiatives
- There will be a AIDA-2 discussion next
week. A software work-package (nor purely a continuation of the
existing WP2) is very likely.
from the LIM meeting (Benedikt)
- There was the first LIM of the year. Two
main issues discussed:
- Use of Jenkins for automation in the
the development process and building releases. The tool is going to be
used by 3 experiments (CMS, Alice, LHCb). It make sense to standardize
the configuration (puppet-rization).
- Two new releases: 67a and 67b.
Frontier reported a problem 67a, so 67b just contains a new version of
- There is no need for a release with
- As soon there is a version of ROOT-6
with all the tests of LHCb passing there will be a new tag that LHCb
will like to use for large scale validation.
- The 5.34 version requested by ATLAS
does not need a full release of the LCG stack so far.
- New build strategy for ATLAS
- ATLAS is going to migrate to CMake.
- JIRA and Savannah migration
- They run into problems with different
- The plugin has not been migrated to
the new JIRA version
- Apologies for the delay
- Federico is the person that is taking
care of it now.
- New licenses and machines are ready
and a person assigned to it. It will cover version 7.
- Integration with Grid software
- Because of C++11 it implies to build
all the Grid clients together.
- Nicolo will probably be the person to
be coordinating for the versions and packages.
- Beta 2 was release with a delay of 1
week to get fixes for blocking issues required by LHCb.
- A new version of TTreeIndex to support
64 bit has been added on request of ATLAS.
- Validated the COOL/CORAL in LCG67b
after the change of frontier client (there was a bug in frontier
client in LCG67a).
- Did a lot of progress in the port of
PyCool to ROOT6. The main pending issue is the inability of catching
c++ exceptions in Python: this affects tests using exceptions, but
also affects normal use cases where exceptions are used for template
overload resolution. If requested, will prepare CORAL/COOL tags for a
complete stack based on ROOT6 beta2.
- There was a development release last
Friday. It contains some fixes to release 10.
- Patch for release 10 is in preparation
and will be ready by the end of the month.
- Positive meeting for the Geant-V
- CernVM-FS 2.1.17 last steps on beta
testing. One issue found by LHCb (files chunks)
- Production version of CernVM 3.0 was
released end of January, with the associated repository.
- Ongoing discussing with ATLAS and CMS
on the deployment of CernVM on Openstack.
- LHCb encourages users to use the new
version. So far the feedback has been very positive.
- There is worry around the
sustainability of the support. The Computing Coordinators have made
the statement that not only CernVM-FS but also CernVM is strategic for
LHC, providing an effective way to distribute the software of the
experiment and to recreate the experiment software environment on
- Ongoing work for the simplification of
setting up a cluster with Openstack.
- The ATLAS deployment at the 'online
cluster'. They will move to CernVM for the next iteration. The Cloud
scheduler (which is what they use in ATLAS) prevented its use. Jakob
is helping them now.
- Having a look at gcc 4.9 for the
release. The interest is that some of the C++14 features are already
- CMS have provided a patch for ROOT 5
to make it work for the Multi-threaded CMSSW. Pere requested that a
ROOT I/O presentation with these changes.
- Bill is making good progress in the
integrating with ROOT 6.
- Next meeting on March 13th.
