Abstract: This paper introduces a forest fire monitoring algorithm based on high-performance cluster computing platform, when the forest fire happens, to get fire information and share different data resources quickly. It introduces the high performance computing platform based on processors, and the parallelization realization of fire identification algorithm based on satellite image, analyzes various factors which affects the operation efficiency. Experimental results show that when chooses the rational number of parallel task, the algorithm can effectively improve the efficiency.

Key words: remote sensing technology, cluster, parallelization, operation efficiency, forest fire
