Eliminating CPU Bottleneck of File I/O on Ultra High Speed Storage Environments

本文的研究成果包括提出了一种新的排序和连接操作的执行方法，这是关系数据库系统中重要的操作。细节在DEIM 2013上展示。此外，本研究还有助于构建一种低延迟的数据流并行处理方法。它减少了CPU内核之间的通信次数，实现了低延迟处理。该方法在DEIM 2012上进行了展示，并在论坛上获得了最佳论文奖。此外，它还发表在IEICE期刊上。

The achievements of this research include proposing a new execution method of sort and join that are important operations in relational database systems. The details were presented at DEIM 2013. Also, this research contributes to build a low latency parallel processing method for data streams. It reduces the number of communications between CPU cores and realizes low latency processing. The proposed method was presented at DEIM 2012 and it won a best paper award in the forum. In addition, it was published in an IEICE journal.
