Implementation of the EMI Execution Service (ES) specification will ensure inter-operability in Grid infrastructures, including the NGI-UA, since a single set of specifica-tions and a common job management interface will be used.This paper presents the results of the study of applying of the EMI-ES specification to provide interoperability in the Ukrainian national grid.During the research keracare twist and define cream next features were studied: the structure of the EMI-ES specification, developed on the basis of the analysis of computing services in industrial environments by Working Group OGF Production Grid Infrastructure (PGI), functionality in data staging, presented by elements of stage-in (file download), and stage-out (extraction john tory hair of results).The modular structure of the EMI-ES, which allows launching cross submissions between different middleware and computing elements, is represented.
The execution order of the ES submission command is reviewed and shown schematically.The implementation of the EMI-ES service in middleware ARC is described.Next steps in development of the EMI Execution Service (ES) are also described.
