1. Spend plan regarding LHC resource requests and Tier-2 h/w purchasing timing.
=======================================================================
DB provided an update on the 20% increase in resource request from the LHC experiments for 2017 which will then continue, raising the base level for 2018. DB needs the necessary figures in order to respond and plan for options, particularly on whether Tier2 spending can be used for Tier1 this year and repaid during the project. AS mentioned efforts into UKT0 activity for larger sums of monies last week and he will now progress this. Scenarios should be worked up for FY 16, 17, & 18 to understand options available and a table produced containing disk, CPU, capital, etc for each FY; options for bringing forward spend; how much of the pledge would be met; and what would remain in the budget going forward. In parallel the UKTO work currently being considered may impact changes and total pledge amounts in the future.
Forward planning needs to be put in place to assess possibilities and draw some conclusions/make recommendations. AS will ascertain whether it is preferable to funnel resources into Tape. If Tier2 funds must be spent on Tier2 this year strategic decisions require to be made at large sites, but it may be preferable to spend at Tier1 this year and Tier2 next. AS, PG & DB will meet tomorrow via Skype at 9.00am to discuss in advance of DB’s meeting with Tony Medland.
ACTION 609.1: AS will supply DB with figures requested and allocated of £554K for Capital last October.
2. OSC documents – Progress
===============================
PG summarised there is not much update from his email on Friday relating to translating information into the new format and bringing quarterly reports up to date and new metrics. This is being edited with DB’s comments.
3. Report on plans for AAAI project with Dirac as well as proposed reporting – Jens Jensen
==================================================================
Time did not allow this presentation to take place, Jens will forward the Powerpoint slides for PMB to discuss and comment.
4. AOCB
=======
a) Tier-1 review date – AS will confirm this asap.
5. Standing Items
===================
SI-0 Bi-Weekly Report from Technical Group (DC)
———————————————–
Not present and no report submitted.
SI-1 Dissemination Report (SL)
——————————
Not present and no report submitted.
SI-2 ATLAS Weekly Review and Plans (RJ)
—————————————
Problem with pilots for a brief period last week, this was an ATLAS issue now resolved.
SI-3 CMS Weekly Review and Plans (DC)
————————————-
Not present and no report submitted.
SI-4 LHCb Weekly Review and Plans (PC)
————————————–
Not present and no report submitted.
SI-5 Production Manager’s report (JC)
————————————-
Not present and no report submitted.
SI-6 Tier-1 Manager’s Report (GS)
———————————
General:
– Owing to particular staffing issues we will have limited cover for any problems with the tape system next week.
Networking:
– The Change Control process has approved the replacement of the UKLight Router, which will take place on Wednesday (5th October).
Castor:
– Testing of Castor 2.1.15 is still proceeding OK – and is largely complete. However, a review of staff availability means that this update will be carried out in the New Year, with the intention of completing it by the end of January.
– There was a problem with the LHCb Castor instance over the weekend. LHCb raised a GGUS ‘alarm’ ticket on Sunday (yesterday) morning. The problem was fixed around lunchtime.
Tape System:
– An intervention (by Oracle) is being planned for the first week of November. It should need an outage of a short working day for each of the libraries.
Echo email from AM – DB requested how far this was off from the level required. AS confirmed the software has been tested and looks very promising. Alistair can provide an update on steps and time schedule in due course (previously he suggested end October).
SI-7 LCG Management Board Report of Issues (DB)
———————————————–
Nothing to report.
SI-8 External Contexts (PG)
———————————
Not present and no report submitted.
Next week several PMB members will be attending CHEP and DB is in California the following week and may not be possible, though ad-hoc meeting may be possible if necessary. The next PMB will therefore take place Face-to-Face meeting is arranged on 24th October.
