Development of the data buffer holding time-series data across multiple applications

概要

Cross-reference simulation refers to a computational model composed of multiple parallel simulation codes wherein, during the simulation process, some time-series data calculated by simulation code is referenced. In order to furnish an efficient and user-friendly methodology for conducting cross-reference simulation, a framework named CoToCoA (Code to Code Adapter) is currently in development. Through the utilization of CoToCoA, minimal modification to the simulation code is necessitated, and communication overhead is kept to a minimum. To enhance performance, a function featuring a specific data buffer has been devised to facilitate one-sided data communication among multiple simulation codes. The communication overhead associated with one-sided data communication is significantly lower than that of two-sided communication. The employment of a specific data buffer mitigates communication loss arising from one-sided communication and ensures that the calculation on one side of the data communication remains undisturbed by the other side. Consequently, the impact on workload balance is negligible.
