Abstract

Recent studies [17, 12] show that leveraging benefits of high performance interconnects like InfiniBand, MapReduce performance in terms of job execution time can be greatly enhanced by using additional features like in-memory merge, pipelined merge and reduce, and prefetching and caching of map outputs. In this paper, we validate that it is time to have a new performance model for the RDMA-based design of MapReduce over high performance interconnects. Our initial results derived from the proposed analytical model matches the experimental results within a 3--5% range.
