0. Ongoing Action List
10902 - The top Error Messages monitor is not working, Marcows and/or Victor will check it
10910 - glexec deployment is progressing. Developers start to consider SCAS replacement by the
Argus service, no time line yet. glexec usage should be transparent with this respect
10911 - Sites can be now effectively banned by banning the local SEs for the data processing
tasks. TWiKi documentation will be provided (Action: Andrew)
10916 - Web Portal releases are now tagged and deployed independently of the DIRAC releases,
the procedure is agreed and used by the Web portal developers.
10918 - Certification system on volhcb05 proved to be quite useful. It is now running only WMS
components. The Certification system should be moved to a more powerful machine (volhcb12)
and other systems should be deployed, most notably Production Management.
10919 - Migration of the DIRAC services to SLC5 can now proceed. This will be done by gradually
setting up new SLC5 machines and moving services from the SLC4 machines. Joel and Ricardo
will come up with an exact scenario in which order and to which machines the services will
be migrated.
11124 - Joel will ressurect the SVN repository which is down now.
11223 - Roberto will investigate the possibility of using C-MON interface of the CREAM CE.
This is necessary to query the CE status in order to decide whether new pilots can be
submitted to the CE.
11265 - Production Statuses will be sorted in a logical order. Andrew will provide a sorted list
of statuses to Matvey
1. Production issues
- Stripping workflow is prepared but still waiting for DaVinci options to handle properly the output
data naming. Still should be finalized and tested. The subsequent merging step is specific for stripping
jobs since event tag collections should be also generated in a separate step. This is the top priority.
- As soon as Ganga will be comissioned to use DIRAC v4r19 version, it will be able to run on SLC5 platform.
This testing is ongoing
- Ganga version using DIRAC versions prior to v4r17 will be declared depricated (very few users are concerned).
With the new DIRAC release, the old Sandbox service will be discontinued.
- volhcb04 access is screwed. It was decided to rather move the volchb04 services to an SLC5 machine.
2. DIRAC releases
- v4r19+p1+p2 releases are in production. The Certification machine was used for the first time to test
the new releases. The main new features are possibility to ban SEs and updated Production State Machine
with automated agents to check and finalize productions.
- a new release will have an update major version v5r0. This is necessary to update the binary distribution
for MySQL, pyGSI and matplotlib packages.
3. DIRAC tasks
Roberto reported that the Demo session during EGEE'09 in Barcelona went quite well. A real production was extended
for the demonstration using Production Request interface. User jobs submission via Ganga using the output data from
the demo production was demonstrated. The Site map was also presented.
Framework: Ricardo reported that a new service, agent and command line tools to facilitate updating the CA, CRL files
are provided. The dirac-install script already makes use of it.
4. AOB
The next PASTE meeting will be during the LHCb Software Week. On Friday morning there will be a Core Computing meeting
which will discuss the virtualization techniques. Will be nice to ensure the participation of the DIRAC developers
in this meeting
There are minutes attached to this event.
Show them.
