Short summary

We propose a butterfly implementation for data transfer. Although the butterfly implementation outperforms the existing implementation (the P2P implementation) in many cases, it degrades the performance in some cases. So we design and implement an adaptive data transfer library that automatically chooses an optimal implementation between the P2P one and the butterfly one and also further improves the performance based on the butterfly implementation through skipping some butterfly stages.
