Prediction of long-term global climate change and the related regional extreme weather events are very serious issues for sustaining security, prosperity and future of the world society. Vigorous progress in high-performance computing and information technologies has enabled climate scientists to simulate the long-term global climate change and regionally extreme events as wind storm, typhoon, hurricane, torrential rain, drought, heat wave, floods, frost etc.. This has been achieved by innovating climate/weather or earth system models with supports by high performance computing and globally networked observation technologies. Based on these advances, climate modeling community is now producing projection data, which are expected to make significant contributions to IPCC’s assessment reports.
High-end computing technology, especially large-scale supercomputer, is ceaselessly and rapidly growing and its capability is predicted to break a wall of exaflops around 2018-20 or so by USA. Also some countries in Europe, Japan and China would be following to reach to the exaflop computing age. Green and high-capability computing are now pushing venders to develop new heterogeneous architectures as multi- or many-core with GPU and accelerator or so for attaining more flexible computing capability. These trends in computing environments gradually and strongly impact on simulation-software technology in modeling global and regional climate change or earth system sustainability and global system.
Since climate modeling, computational science, and computer engineering have been intimately collaborated so far, it is now required for folks to re- tie up more closely and internationally, in order to cope with the coming new environment of computing.
Thus, the objective of this workshop is to bring together climatologists, computer scientist and engineering people for discussing and exchanging latest results of climate change projection and new ideas for the next generation models and simulation, as well as hyper -performance computing environments that are envisioned to be available in the next few decades.
This workshop is basically related to the communiqué of the 6th Japan-US workshop held in Hawaii, March 1998 and is the 15-th in the series having been held in several places in the world, starting with the first one in Hawaii in 1999. Previous Locations are: Honolulu, 1999/ Toulouse, France, 2000/ Tokyo, 2001/ Boulder, 2002/ Rome, 2003/ Honolulu, 2004 / Kona, Hawaii, 2005 / Albuquerque, 2006 / Honolulu, 2007/Honolulu, 2008/Oak Ridge, 2009/Tsukuba, 2010/ Honolulu, 2011 and Maui, 2012.
