Abstract
Global data movement is the most general, and therefore important, function of inter-node communication in the partitioned global address space programming models, such as XcalableMP. Our implementation of it consists of compile-time and run-time optimization for specific cases and run-time processing based on the calculus of common-stride section descriptors for general cases, which allows efficient construction of communication schedules for global data movement. As a result of the evaluation of the implementation on the K computer and a common Linux cluster, it is verified to be effective and useful as a compiler feature in most cases.
