(English Abstract)
These days, big data computing is prevalent and Hadoop MapReduce framework is widely used for its simple programming model. On the other hand, General-Purpose Graphics Processing Unit (GPGPU) has become very popular and various domains of applications have been successfully accelerated using GPUs. In this paper, we propose a method to use GPU within Hadoop MapReduce framework. Then, we propose a static partitioning method that considers different capability of CPU mappers and GPU mappers, and a dynamic scheduling method that deals with a dynamic input size. Compared to a single CPU execution time, the CKY parser on a 14-node Hadoop cluster with 12 CPU cores and 1 GPU per node achieves 245 times speedup. Compared to the execution time on a 14-node Hadoop cluster with 12 CPU cores and no GPU per node, it also achieves 2.5 times speedup. Our proposed approach for both CPU and GPU mapper execution leads to an additional speedup, resulting in total of 2.8 times speedup.
