Revision as of 12:33, 16 May 2011
Detailed agenda: Grid Operations Meeting 16 May 2011
1. Middleware releases and staged rollout
1.1. Update on the status of EMI-1 release (Cristina)
1.2. Staged Rollout (Mario)
gLite 3.2 components:
- VOBOX has been tested at LIP, is now in ready for production.
- L&B 2.1.21 under staged rollout by IFIC, first feedback OK.
- CREAM 1.6.6 and SGE_Utils under staged rollout by LIP. A problem seen due to the latest update of glibc.
The glibc has been updated from glibc-2.5-49 to glibc-2.5-58, before the update of the cream and sge_utils, and we saw segmentation faults in the BLAH component. This may turn to be more general. Sites running cream should check at least the BUpdater<LRMS>.
1.4 Interoperability
Current ongoing points in the integration task forces:
UNICORE:
- Very happy to be number one in the GOCDB development queue with a new solution for requirement https://rt.egi.eu/rt/Ticket/Display.html?id=975 which worked as a showstopper. Promised timeline now within one month.
- For monitoring we don't need an XML based workaround now: everything else finished, just waiting for GOCDB integration.
- A more tight collaboration with Belarus: Good news: The NGI_BY UNICORE Accounting service Andrew. Lukoshko presented at the EGI UF 2011 got permission to go Open Source. An English version and translated documentation is being prepared for initial export to Sourceforge. NGI-DE already became a non open source version to have some tests and do some comparison.
- A new release of UNICORE RUS accounting system is available from sourceforge. It is major milestone as it completes our move to JMS based architecture with a full fail-over support. It is also updated to USE and 6.4.0 release of UNICORE. http://unicore-dev.zam.kfa-juelich.de/documentation/rus-accounting-1.3.1/
- Discussion on the integration mailinglist about the next GLUE2 based service types names to be integrated in the next stage.
Globus:
- First meeting held on Wednesday 4th May. Wiki: https://wiki.egi.eu/wiki/Globus_integration_task_force and new mailinglist globus-integration-tf@mailman.egi.eu
- Next meeting will be a meeting mostly dedicated to accounting and has a closed slot in the first European Globus Community Forum (EGCF) this week in Munich http://www.ige-project.eu/events/egcf1. There will be possibility to phone in: Wednesday 15:35-16:15 CEST
- Question on all NGIS on desired timelines for Globus integration to determine need for a second Early Adopter team for Globus at current stage.
- New service types: Globus Online instead of RFT, IIS instead of MDS
- The first IGE release announced for end of April is still being finalized. Second one at the end of this year will contain Argus.
- IGE is taking over the UK developed Grid-SAFE for accounting, currently planned to be installed on the LRZ testbed and then be integrated in the IGE releases.

2. Operational Issues
2.1 Workdir and tmpdir for parallel jobs
New input from NGI_CH: Currently at CSCS the solutions in use are: CREAM JobWrapper and ARC custom submission scripts. Those solutions are obviously middleware specific.
The custom TMPDIR should be used also to solve the local disk throughput limits: with 16 or 32 cores the local disk can be stressed beyond its limit, and high performance network file systems have better performance. Experiences from other site administrator on this topic performance are needed to consider solutions for this problem.
The customization of a job workdir should consider both the job type and the job disk performance requirements. Can the second requirement be attached to the job submission? Is really needed?
2.2 Open Issues
- gLite 3.2 VOMS not published in the information system.
- It is not easy to automatically check the progression of this task, please ask to your site admin to take care of this.
- Please check here the full list of VOMS registered in the GOCDB and the ones that are being published in the information system
- Upcoming surveys (will be announced in the tomorrow's OMB)
- Batch system utilization and distribution
- BDII high availability best practices.
