Abstract
In this paper, a GPU-based parallel algorithm is proposed to improve the processing efficiency of motif recognition algorithm. The work includes a serial motif recognition algorithm and a parallel algorithm based on GPU. Our GPU parallel algorithm is compared with the serial algorithm by using of 1 KB promoter data of five kinds of plant genes upstream regions. The experimental results show that a factor of 20 speeds can be achieved. It means that there are a lot of advantages by GPU parallel technology on gene motif recognition algorithm. It is significant to the great amount of data analysis work of genetic sequence.
