• 論文抄録 / 内容記述: Cross-reference simulation is a calculation model coupling multiple parallel simulation codes when at least one simulation code needs to read the data in other simulation codes to do its own calculation. To provide a solution that can carry out cross-reference simulation efficiently and conveniently, a cross-reference simulation framework CoToCoA is being developed. It allows CoToCoA users to implement cross-reference simulation with minimal modification on simulation codes while the overhead is restricted as much as possible. In this paper, a function with a specific data buffer is developed to implement one-sided data communication among multiple simulation codes with minimal communication loss. Generally, a simulation code calculates and updates the data in each time step. Then the former data will be overwritten. If there is no synchronization or barrier, other simulation codes may miss data at some time step due to the overwriting. To solve this issue, a specific data buffer is utilized to save the data at each time step. No data will be skipped as long as the data buffer is not full. Meanwhile, the number of data communication calls can be reduced significantly.
