The 2014 Worldwide LHC Computing Grid (WLCG) Collaboration Workshop occurred from July 7 to July 9 in Barcelona, Spain. (A full set of slides is available here.)

While recent operational events were covered, the majority of the focus was on future planning for LHC computing. The CERN Tier 0 and WLCG working groups on Middleware Readiness, IPv6 Adoption, Multicore Jobs and Cloud Resources reported recent accomplishments and challenges. The OSG and the European Grid Infrastructure reported on recent happenings within various high-throughput computing infrastructures. Overall there was wide agreement that WLCG has successfully navigated LHC Run 1, has evolved sufficiently for Run 2, and much larger evolutions lie ahead for Runs 3 and 4. Long-term challenges are being discussed and plans and being constructed. However, one thing is certain, effort resources will continue to be strained during the next years of WLCG so collaboration, wise allocation of effort, and prioritization based on experiment needs will be vital.
