Abstract
MapReduce is a popular programming paradigm for processing big data. It uses the master-worker model, which is widely used on distributed and loosely coupled systems such as clusters, to solve large problems with task parallelism. With the ubiquity of many-core architectures in recent years and foreseeable future, the many-core platform will be one of the main computing platforms to execute MapReduce programs. Therefore, it is essential to optimize MapReduce programs on many-core platforms. Optimizations of parallel programs for a many-core platform are viewed as a multifaceted problem, where both system and architectural factors should be taken into account. In this paper, we look into the problem by constructing a master-worker model for MapReduce paradigm on the TILE64 many-core platform. We investigate master share and worker share schemes for implementation of a MapReduce library on the TILE64. The theoretical analysis shows that the worker share scheme is inherently better for implementation of MapReduce library on the TILE64 many-core platform. © 2013 Elsevier B.V. All rights reserved.
