Attending: Brian, Jens (chair+mins), Dan, Winnie, RobC, Teng, Sam, Duncan, Matt, Robert 0. OBP (incl Alessandra's turlable but missing files) VidyoConnect annoyances - if you can keep VidyoDesktop working then by all means do so. No new blog posts. Alessandra's operational issues - reported solved just as the meeting started - ATLAS issues with 3rd party HTTP copying to/from DPM: sites that have upgraded their DPMs are recommended to turn DOME off. Clearly issues with testing of DPM releases; Italian sites had been running this release and the problems were not reported. Matt upgraded his DPM to CentOS7 and found problems; not enough file descriptors, puppet problem. While it was reported fixed by DPM, the fix has not been rolled out yet! Is it still worth having the hackathon at GridPP if DOME is not to be used? Yes, it will be good to get experience with it and eventually the fixes will be rolled out. DUNE had requested HTTP 3rd party copying but this requirement then cannot be met yet for DPM sites. 1. DOMA (cf Brian's mail) Sam already involved; also Imperial is represented on the WG. 2. Forward look We now have about a week to finish it - everyone should have a look and comment and read (although not necessarily in that order). Duncan, in particular, is requested to contribute Words of Wisdom on networking. The forward look is up to the big step in LHC data expected in ~2025. Information systems were discussed yesterday https://indico.cern.ch/event/750291/ 3. GridPP41 & hack day Not many people upsigned yet, mail Louisa directly if you want coffee. 4. AOB Brian yes! and have DPM devs announce version! even if only do small(er) amount of work, I posted so that we can track it. BD Daniel There should be some provision in GridPP6 for "research" in to solutions that will work for the HL-LHC. With predicted massive rise in storage requirements and network transfers there is a clear overlap with this group. What that research should be I'm not sure? DP Brian AIM of GRIDPP6 to move away from gsiftp/xroot/SRM ??? more geograpically distributed systems BD (mail jens for doc link) Brian also want a section of how to help integrate external Storage systems (ie how do we explot cloud storage if required to.) 100G bandwidth issues. intergation into LHCONE ? rucio to replace DFC in dirac? at least need to be able to interact with them ive now booked contact louisa BD Today at 10:48 AM
