Will it ever be possible to improve the resolution of weather prediction to such an extent? Only time will tell, along with the success of using complex solvers tested on facilities like the University of Bath's Aquila HPC service<\/a>.<\/p>\n

Dr Eike Mueller won the prize for best presentation at the\u00a02013 High Performance Computing (HPC) symposium at the University of Bath.\u00a0 Since September 2011 Eike has been a PostDoc in the Department of Mathematical Sciences at the University of Bath where he works on a HPC driven NERC funded project for improving the accuracy of global weather and climate prediction models<\/a> for the Met Office.<\/p>\n

Background to Eike Mueller's work<\/h3>\n

The UK Met Office provides\u00a0global,\u00a05 day weather\u00a0forecasts.\u00a0\u00a0Data is fed into a computational model,\u00a0this data is sourced\u00a0using a\u00a0grid with reference points 25 km apart.\u00a0 The aim is to increase the resolution of this forecast and use data from reference points 1 to 2 km apart.\u00a0 This requires a rethink of\u00a0the computational model being used.\u00a0 Together with Professor Rob Scheichl, Eike is improving the performance of the solver for the global pressure correction equation, which is one of the computationally most\u00a0important components\u00a0of the model.<\/p>\n

Rethinking computation models - how to make the most of Graphical Processing Units (GPU)<\/h3>\n

Traditionally users of the Aquila HPC service at the University of Bath run jobs over long periods of time, using a smaller percentage of the central processing power available from Aquila.\u00a0 Bath University Computing Services (BUCS) works to make sure that all requests for using the service are run as efficiently as possible.<\/p>\n

Dr Mueller's work is different from these more traditional jobs.\u00a0 He is the first at the University of Bath to take advantage of the newly installed NVIDIA Fermi GPUs, which offers a total of 3,072 GPU cores.\u00a0 In addition, his work requires using the majority of the Aquila's capacity for very short periods of time. He is using Aquila to develop and test the performance of algorithmic and parallel scalability of solvers for elliptic partial differential equations in weather and climate prediction on novel computer architecture (in this example GPUs).\u00a0 Dr Steven Chapman from BUCS has provided support to assist Eike in getting the most out of the GPUs on the Aquila cluster.<\/p>\n

What is next for Dr Mueller's work?<\/h3>\n

Eike is currently extending the work he presented in his talk at the HPC Symposium to run his solver<\/a> on the EMERALD cluster, the UK's biggest NVIDIA GPU-accelerated supercomputer<\/a>. In the future he also plans to test the scalability of his code on the TITAN supercomputer<\/a>, which is currently the second fastest computer in the world.\u00a0 Having a local HPC facility allows him to test his work and solve any issues that result from the tests.<\/p>\n

And the the weather on Sunday on campus?<\/h3>\n
