基于Hadoop Streaming的Last比对软件并行化的研究与实现
Parallel implementation for Last based on Hadoop Streaming
摘要
Abstract
With the arrival of the next generation sequencing technology, stand-alone version of the Last alignment soft-ware is not good enough for massive data processing while Hadoop Streaming technology can solve the problem by rapidly deploying Last software to the distributed cluster. It will be ensured to a balanced and effective data segmentation as well as control of the parallel granularity by the NFS-based customizing segmentation of data set and Partitioner based distribu-tion of tasks. Experimental results show that this method can guarantee the same results with the stand-alone operation, effectively reduce the running time with a relatively high speed.关键词
