Abstract
This talk presents the overall design and implementation of the MPI communication library for the K computer. The K computer introduces the Tofu interconnect, 6D torus/mesh topology, for higher performance and availability for peta-scale systems, however, present several issues to increase performance, availability and usability. In this talk, these issues, approaches, designs and implementations are discussed. Performance evaluation results are also presented.
