BS PD ISO/IEC TS 18508:2015 speci es the form and establishes the interpretation of facilities that extend the Fortran language de ned by ISO/IEC 1539-1:2010, ISO/IEC 1539-1:2010/Cor 1:2012, and ISO/IEC 1539-1:2010/Cor2:2013. The purpose of this Technical Speci cation is to promote portability, reliability, maintainability, and effi cient execution of parallel programs written in Fortran, for use on a variety of computing systems.
This Technical Speci cation does not specify formal data consistency model. Developing the formal data consistency model is left until the integration of these facilities into ISO/IEC 1539-1.
