Dear Cray User Group colleagues,
The European Centre for Medium-Range Weather Forecasts (ECMWF) would like to invite you to CUG 2016 in London in May 2016. Our theme for this meeting is “Scalability”. Exploiting parallelism on all architectural levels and improving the scalability of all codes is both vital and challenging for Numerical Weather Prediction.
ECMWF’s first operational forecast in 1979, at 210 km global resolution, took five hours to run on a single-processor Cray-1A. Today, two Cray XC30 systems, each with more than 84,000 cores, give us more than twenty million times the peak performance of that first Cray allowing a much larger and more advanced forecasting system featuring a high-resolution global model resolution of 16 km and a 51-member ensemble with a model resolution of 32 km.
Clearly, HPC technology developments are influencing the directions our research will take. This has never been truer as we face the challenges of ever-larger heterogeneous systems and exponential growth in data. Founded on the principal of international collaboration, ECMWF is delighted to have the opportunity to host a meeting that will be an opportunity for users, developers and administrators from all over the world to exchange ideas, solve problems and discuss the future of high performance computing.
Established in 1975 as a major initiative in European scientific and technical co-operation in meteorology, ECMWF is an independent intergovernmental organization supported by 34 states and is both a research institute and a 24/7 operational service, producing and disseminating numerical weather predictions to its Member States. The supercomputer facility (and associated data archive) at ECMWF is one of the largest of its type in Europe and Member States can use 25% of its capacity for their own purposes.
We look forward to seeing you in London, a metropolis steeped in history with a rich cultural life and many culinary delights to enjoy. From Buckingham Palace and St Paul's Cathedral to the more recent London Eye and the Shard skyscraper, there is no shortage of landmarks to visit. Top museums, such as the British Museum, the Natural History Museum and the Science Museum, are free of charge. We are sure you will enjoy your stay.
