High-performance Computing

For many algorithms, execution cannot be handled by a single computer in a practical period of time. For example, weather simulations for forecasting, pharmacokinetics (the influence of a certain medicine to the human body), and computational fluid dynamics used for aircraft development take months and years to process. Another kind of example is use of CT (X-ray computed tomography); it takes approximately two minutes after taking a large series of two-dimensional radiographic images to visualize a three-dimensional image of the human body using CT. Although two minutes is short, it is too long to use the CT during a surgery practically.
As GPUs and supercomputers comprise several hundreds, thousands, or even tens of thousands of processing units running simultaneously, their collective work is called parallel processing.
My researche aims to increase processing speed so that these kind of tasks may be executed using parallel processing between supercomputers, multicore CPUs, and GPUs. Parallel processing, despite its many theoretical and technical problems, is a strong and growing research field with a great potential to contribute to the society.
