Effective Calculation with Halo communication using Halo Functions
The issue of halo communication is the decrease of parallel scalability. To overcome the issues, we have introduced "Halo thread" to our simulation code. However, we have not solved the issue basically in the strong scaling. In this study, we have developed the Halo functions which perform the halo communication effectively. Then we can perform the calculation and communication in a pipeline and obtained good performance.
