Multi-SPMD Programming Model with YML and XcalableMP
This chapter describes a multi-SPMD (mSPMD) programming model and a set of software and libraries to support the mSPMD programming model. The mSPMD programming model has been proposed to realize scalable applications on huge and hierarchical systems. It h

Preface
XcalableMP is a directive-based parallel programming language based on Fortran and C, supporting the PGAS (partitioned global address space) model for distributed memory parallel systems. PGAS is a programming model related to distributed memory system with a shared address space that distinguishes between local (cheap) and remote (expensive) memory access. It provides an easy and intuitive programming model to describe remote data access. PGAS is an emerging programming model for exascale computing. The XcalableMP project has been started in 2008 as a part of MEXT e-science project, led by Prof. Yutaka Ishikawa, University of Tokyo, Japan. The language specification working group were organized by Mitsuhisa Sato, University of Tsukuba, with memb
