A new research collaboration between A*STAR’s Institute of High Performance Computing (IHPC), Sembcorp Marine Ltd, University of Glasgow and University of Glasgow Singapore (UGS) aims to improve make a ship’s hydrodynamics and energy efficiency. The four organisations signed a memorandum of understanding (MoU) to collaborate and develop new hull designs for large ocean-going vessels.

Under the three-year MoU, IHPC, Sembcorp Marine Ltd, University of Glasgow and UGS will use computational modelling and visualisation technologies to design vessels with improved hydrodynamics for better fuel efficiency. In addition, they will collaborate and innovate on features to reduce harmful exhaust emissions and discharges by enhancing the vessel’s scrubber and ballast treatment systems. Currently, maritime transport carries about 90% of all international trade and accounts for 3% of global greenhouse gas emissions.

Eight national laboratories—Lawrence Livermore, Argonne, Brookhaven, Lawrence Berkeley, Los Alamos, Oak Ridge, Pacific Northwest and Sandia—are combining forces with the National Center for Atmospheric Research, four academic institutions and one private-sector company in a 10-year project to use high performance computing (HPC) to develop and to apply the most complete climate and Earth system model.

The project, called Accelerated Climate Modeling for Energy (ACME), is designed to accelerate the development and application of fully coupled, state-of-the-science Earth system models for scientific and energy applications. The plan is to exploit advanced software and new high performance computing machines as they become available. The initial focus will be on three climate change science drivers and corresponding questions to be answered during the project’s initial phase:

As part of its 2014 ASCR Leadership Computing Challenge (ALCC) awards of processor time (totaling more than 3 billion processor hours), the US Department of Energy’s (DOE) Office of Science has awarded 15 million hours on Oak Ridge National Laboratory’s (ORNL) Titan supercomputer to a project led by General Motors, and 17.5 million hours on Titan to a project led by ORNL with Ford and Convergent Science as co-investigators. Titan is current Nº2 on the Top 500 Supercomputer list, and offers 27.1 petaflop (PF) peak processing capacity, with about 300,000 compute cores.

The two projects are part of a larger multi-year DOE-funded project to develop and to apply innovative simulation strategies and tools to maximize benefits of predictive information from high performance computing (HPC) for internal combustion engines. The Principal Investigator on that DOE project is Dean Edwards of ORNL.
