(English Abstract)
In this paper, we propose a similar sequence matching method in data streams using GPU parallelism. Unlike similar sequence matching in databases, similar sequence matching in data streams should be performed in real time since a large amount of data is continuously generated. In this paper, we use the parallelism of GPU to process large amount of data with real time property. GPUs have the advantage of high throughput by processing a large amounts of data in parallel. However, it is inefficient to perform similar sequence matching whenever a new data item arrives due to the overhead of data transformation and GPU function calls. To solve the inefficient issue, we propose a new similar sequence matching technique which reduces the overhead by using a batch method collecting input data for a certain period of time. As a result of the performance evaluation, we show that the proposed method significantly improves the performance compared to the method using CPUs.
