Tuesday 12th December A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here

• There are problems with the new CA trust anchor release. The Tier1 plans to update to version 1.88 on the 12th Dec.
• The WMS service at RAL will be decommissioned at the end of December.
• Allocation in Echo for ATLAS increased to 4.1PB. They now have 4PB in datadisk and 100TB in scratchdisk. This is part of the gradual increase of their usage to 5.1PB.
• LHCb D1T0 disk space in Castor has been very full a week or so ago. Discussions with LHCb are ongoing about the next steps with this problem.
• There was a problem of high packet loss for traffic to/from the Tier that passed through the RAL core network (and firewall) on Monday (4th Dec). The problem started at midnight and was fixed around 15:30.

Wed 06 Dec

• Another success story - CERN@School running machine learning at QMUL
• Technical events coming up - hepsysman and cloud workshop at Crick. We ought to do something Useful or Interesting.

Wed 15 Nov

• More xcache progress at some sites; less at others who may be blocking on dependencies or be busy with Other Things(tm)
• Some interest in following the non-X.509 authentication/authorisation

Wed 08 Nov

• Not (very) modest at all progress on xcache testing... from Chris at RALPP

Wed 01 Nov

• (very) modest progress on xcache testing...
• Except that RALPP has it fully working for dCache - hope to get full report next week

Tuesday 12 Dec

• Vcycle updated for Glance API 2.0 and to support Vacuum Pipe VM definitions.

Tuesday 14 Nov

• Single processor LHCb stoppable Monte Carlo VMs running in a mixture with fixed length 8 processor ATLAS VMs and single processor GridPP VMs. Please get in touch if you are running Vac and want to try this.

Tuesday 24th Oct

• A talk on end-to-end validation of any site's APEL accounting was presented at the WLCG Accountuing Taskforce meeting, 19th Oct. There slides exist here: https://indico.cern.ch/event/673843/contributions/2756986/attachments/1542818/2420233/blackBoxAccTesting.pdf

Monday 16th January

• The discussion topic for next week will be accounting comparisons. Please note Alessandra's comments last week.

Monday 14th November

• Alessandra has written an FAQ to extract numbers from ATLAS and APEL avoiding the SSB.

Monday 26th September

• A problem with the APEL Pub and Sync tests developed last Tuesday and was resolved on Wednesday. This had a temporary impact on the accounting portal.

• APEL status: An issue at Sheffield?

Tuesday 12th Dec 2017

Resources requirements for CMS have been increased.

https://www.gridpp.ac.uk/w/index.php?title=GridPP_approved_VOs#VO_Resource_Requirements

Jobs require an address space larger than the memory size specified above. Sites should allow processes to use at least 6GB of virtual address space more per core than memory to accommodate the large amount of shared libraries used by jobs. (For a typical 8-core pilot that would translate into a VZSIZE limit of at least 64GB.)

Nov 2017

VOMS servers located at CNAF have been knocked out due to some flooding. It is not known when they might be recorvered. Hence, at present, there are no VOMS servers at all for both planck or ipv6.hepix.org. And a single new VOMS server has been provided for enmr. See the VOMS records in the Approved VOs document for details.

Tuesday 5th Sept 2017

New Approved VO. SKA European regional data centre, skatelescope.eu

https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs

This VO is ramping up and has requested support. Andrew McNab is the contact person for GridPP.

General note
