Evaluation of Re-Deployment for Environment-Adaptive Software

To use heterogeneous hardware, programmers needed sufficient technical skills such as OpenMP (Open Multi-Processing), CUDA (Compute Unified Device Architecture), and OpenCL (Open Computing Language). Therefore, I have proposed environment-adaptive software that enables high-performance operation by automatically converting and configuring the code once written, and have been working on automatic conversion and proper placement. However, until now, where to initially place the converted application has been considered, but the overall optimal placement has not been considered in consideration of the placement status of other users. In this paper, as a new element of environment-adaptive software, I study the relocation during operation, which improves the overall user satisfaction by considering the placement of other users, using a linear programming method. It was confirmed that it can be properly rearranged through simulation experiments.
