D5.3: HPC Infrastructures Workshop # 6

A 6th European Workshop on HPC Centre Infrastructures was organised by SNIC-KTH, near Stockholm, with CEA, CSCS, LRZ, PSNC, and BSC as the organising committee. This workshop, upon invitation only, was very successful with 73 participants coming from Europe, US, and Australia. In addition to the standard topics (presentations from vendors and sites), the Workshop focused on two important subjects: Large swings of computer centre power. Pre-Commercial Procurement targeting energy efficiency. The PRACE closed session at the end of the workshop gathered 34 attendees and gave the opportunity for exchanges between experts from the PRACE sites. The workshop made the identification of important trends and assessments on the situation of Europe in terms of energy efficient large HPC centres possible
