| Outline of Final Research Achievements |
Autotuning is a technology aiming to attain good execution performance on various computational environments by preparing variabilities within software and letting the software itself control the variabilities. In this research, we aimed to develop methodology to infuse variabilities and control mechanism which are unintended or even unknown to existing codes, to attain autotuning even if novel computational environments and novel variabilities become newly known.
We have shown that, by using Xevolver, which is developed by our team members, we can infuse variabilities and autotuning mechanisms which is unknown to the original code. However, it became clear that we need to fully analyze the original code before applying such infusions.
