Overview

XcalableMP, XMP for short, is a directive-based language extension which allows users to develop parallel programs for distributed memory systems easily and to tune the performance by having minimal and simple notations.

Support typical parallelization under "global-view model"

XMP enables parallelizing the original sequential code using minimal modification with simple directives.

Support coarray to use one-sided communication easily under "local-view model"

Programmer can use coarray syntax in both XMP/Fortran and XMP/C. In particular, XMP/Fortran is designed to be compatible with Coarray Fortran.

Combination of MPI and OpenMP

In order to call an MPI program from an XMP program, XMP provides the MPI programming interface. Moreover, OpenMP directives can be combined into XMP as a hybrid programming.
