【 摘 要 】

ND280 is the off-axis near detector for the T2K neutrino experiment. ND280 is a sophisticated, multiple sub-system detector designed to characterize the T2K neutrino beam and measure neutrino cross-sections. We have developed a complicated system for processing and simulating the ND280 data, using computing resources from North America, Europe and Japan. The first key challenge has been dealing with very different computing infrastructure in different continents; a second challenge has been dealing with the relatively large 1.5PB ND280 MC dataset. We will describe the software, data storage and data distribution solutions developed to meet these challenges.
