Attending: Jens (chair+mins), Steve, Sam, John H, Daniel, Marcus, Winnie, Brian, Alastair, Govind 0. Operational blog posts We now have 6 blog posts for the quarter, thanks in no small part to Daniel and his posts on Lustre. This meets the new adjusted target (we agreed with Pete that 8 was too ambitious, and five would be more realistic.) The presentations at WLCG or CHEP would be obvious topics to blog about. Is it best to pre-blog to create interest in your talk or is it better to post-blog so you can summarise the discussion? Or both... if you write only one blog post, perhaps it's better to blog after your talk to summarise the talk and the discussion and your brilliant answers. Operational issues: biomed using too many resources at Liverpool through not using space tokens correctly. This should be automatically fixed once the quota tokens are deployed, but this would initially apply only to DPM. Other implementations may implement something similar as part of their DAV support. Biomed should know better - while grid storage can be confusing for small VOs, biomed has a lot of experience and lots of smart people and should know better... 1. The cloud whatsit thing, CfA (Call for Abstracts) There is a cloud workshop being planned/advertised, to take place 29 Nov at Crick. The proposal is to invite people to submit also some Real Work(tm) so it is not just a day full of powerpoint. The overall theme seems to be "hybrid", so we could interpret this as being hybrid cloud/GridPP, as well as hybrid Cloud/HPC, or the more traditional hybrid clouds (at least two of public/private/community). 2. (Main topic of today) Input to the WLCG and CHEP In particular, note the data session: https://indico.cern.ch/event/555063/sessions/207257/ Alastair had received input from Sam and Jens, Sam's on the overall theme of reducing costs and Jens's on EUDAT (the premise being a shared infrastructure providing storage to a diverse community, which could reduce costs but is hopefully of interest in its own right.) Also accounting could be in scope - we need to revisit that one. People tend to think traditional grid; when new resources are rolled out - e.g. at T1 - From our little flock, Rob, Marcus, and Daniel will be attending; from Tier 1 Alastair and Ian Collier. Posters and slides had to be submitted already at least in draft form - shocking! Alastair offered to send a link to his slides for CHEP in case anyone wanted to comment. 3. Future tech topics - potentially interesting topics / or not... - Named Data Networking? funded activity but not necessarily the best? - INDIGO revisited (EPCC/CCFE/STFC?) - GridFTP transfer detailed paper with chap from NZ NREN - EUDAT B2STAGE (or more generally connecting infrastructures) - Pathfinder project, mostly focusing on authentication, authorisation, and accounting - perhaps talk at dteam? 4. AOB - Daniel mentioned (also sent to list) ECFA look ahead of storage capacities (and capabilities) to 2026, e.g. ATLAS worst case scenario, 2500 PB disk... there are also lookaheads for climate (Brian+Jens involved) and obviously things like SKA. Terabit networks... Daniel Peter Traynor: (05/10/2016 10:01:04) me Lustre stuff which I bloged my blogs are the core of a chep paper on lustre Matt Doidge: (10:37 AM) With my ticket marshall hat on Jens, could you please throw an update at https://ggus.eu/?mode=ticket_info&ticket_id=117683 (the Castor publishing ticket) - even if it's a "Nothing to see here, move along" update. Jens Jensen: (10:38 AM) ...sure :-) discussed with rob yesterday Matt Doidge: (10:38 AM) Ta!
