GridPP Technical Meeting, 10 October 2014 ========================================= Clouds and VMs -------------- ATLAS - Group at CERN using Vcycle to run VMs and jobs on EGI Cloud CMS - Ongoing but not significant changes since last time. Testing Wigner, do other people see differences compared to Meyrin? No one reports any. LHCb - NTR GridPP - Oxford and Imperial OpenStack passing SAM tests since last time All VM-based sites now passing GridPP SAM tests How easy to set up new sites? OpenStack takes time. Vac straightforward. Oxford - Not running very much at Oxford on Vac? VMs are starting. No jobs to be run? Something going wrong? Storage ------- NTR Networking ---------- Chris at IPv6 ~preGDB at CERN this week. https://indico.cern.ch/event/272778/contribution/3/material/slides/1.pdf Slide 7 has results of tests at QMUL and IC.
