Recently, the lack of computational power for analyzing scientific data, and the distribution of knowledge (by scientists) and technologies (for advanced scientific devices) are two major problems which are common in every scientific field. Emerging grid technology provides a new computational platform for a variety of scientific problems. MEG (magnetoencephalography) data analysis is an important research topic in brain science. In MEG data analysis, the lack of computational power and the distribution of knowledge and technologies lead to inefficient diagnoses and analyses of brain functions. In this research, we have built an MEG data analysis system on a grid environment, simulated with Globus grid toolkit, which is an implementation of grid technology. In this system, we attempted to reduce analysis time and to seamlessly integrate computational resources. Our evaluation results show that the system was highly efficient in reducing analysis time. Furthermore, we succeeded in integrating computers on our grid environment to seamlessly transfer data between each other. We believe that grid technology is effective and promising for real-life medical and scientific problems.
