【 摘 要 】

BESIII experiment is operated in the τ-charm threshold energy region. It has collected the world's largest data samples of J/ψ, ψ(3686), ψ(3770) and ψ(4040) decays. These data are being used to make a variety of interesting and unique studies of light hadron spectroscopy, precision charmonium physics and high-statistics measurements of D meson decays. As one of the experiments at the high luminosity frontier, data processing at BESIII is computationally very expensive for large data sets. In this presentation, we report two recent progresses in using high performance computing: a Tag-based preselection for data reduction and GPUPWA, a PWA framework harnessing the GPU parallel computing.
