On September 5, Geoscientific Model Development published the research outcome of Prof. Zhang Shaoqing’s team under the title of “Characterizing Uncertainties of Earth System Modeling with Heterogeneous Many-core Architecture Computing”. 

Over the years, the team has been devoted to the research and development of high-resolution earth system models. To reveal the influence of many-core isomeric computational perturbations on the simulation results of the earth system, the team designed an atmospheric process model that is extremely sensitive to perturbations. The study shows that perturbations caused by different hardware architectures in heterogeneous computing environment do not affect the correctness of simulation results of the earth system. The study provides for the first time encouraging scientific evidence for verifying the reliability of heterogeneous many-core architecture computing and the adaptability of earth system models to new heterogeneous architectures, contributing to the advancement of supercomputing and earth system models.
