Present: Simon Fayer, Adam Huffman, Duncan Rand, Andrew Lahiff, David
Colling, Gareth Roy, Kashif Mohammed, Pete Gronbech, Raul Lopes, Wahid
Bhimji, Andrew McNab, Ewan MacMahon


1. Clouds and VMs
-----------------

ATLAS


CMS

Andrew:

   Jelena at RAL testing analysis jobs on different clouds

   Not much production work at the moment, so harder to test that

David:

   Scale testing at CERN


LHCb

   Using OpenStack at CERN, now running flat-out

   Running much longer jobs, to avoid time wasted with VM turnover

   Deployed new pilot framework

   Still running VMs on clouds and Vac sites

   Started running on EGI FedCloud via OCCI

   GridPP jobs can now run on CERN OpenStack


STFC

Andrew:

   OpenNebula cloud being used for Tier 1 and other STFC testing

   Testing batch system expansion to use cloud resources and shrinkage
   when cloud busy (using HTCondor daemons)

   Not open for external users yet


IC

   Not much to report

   Andrew McNab using IC OCCI interface for testing


Manchester

Andrew McNab

   Vac and Vcycle changes to minimise site admin remotely

   Boot image fetched remotely and provided automatically by Vcycle

   Looking at Vcycle accounting and wider accounting of cloud usage

   Some risk of double counting

   Will test this at IC


Oxford

Ewan:

   Vac being enabled for CMS and APEL accounting being configured

   Adding to site entry in GOCDB should be sufficient for accounting

Kashif:

   OpenStack now running with Neutron and working on OCCI


2. Storage
----------

Wahid:

   pre-GDB on storage protocols

   See pre-GDB summary slides

   https://indico.cern.ch/event/319743/session/1/contribution/2/material/slides/1.pdf

   ATLAS still relying on SRM for deletions, for example
  
   There should be a summary of what sites need to offer to support a
   particular experiment


3. Networking
-------------

Duncan:

   IPv6 F2F meeting at CERN next week


4. HEP Software Foundation
--------------------------

Andrew McNab will talk about how they can help with small projects
like Vac and Vcycle 

   e.g. lack of ability to disseminate technical notes currently


5. Security
-----------



6. AOB
