【 摘 要 】

The Alpha Magnetic Spectrometer (AMS) is a high energy physics experiment operating on board of the International Space Station (ISS). The detector was installed on ISS in May 2011 and is expected to continuously take cosmic rays data through Year 2024 and beyond. The computing strategy of the AMS experiment is discussed in the paper, including software design, data processing, data reconstruction and simulation, detector performance evaluation, and data production overview. In particular, parallelization of reconstruction and simulation of AMS data is discussed in detail.
