Translating Chemical Scripting Languages to Unified Job-Description Language on Chemical-Grid

Abstract

Unified Job-Description Language on Chemical-Grid (UDLC) is a domain-specific language designed to write full-function chemical jobs on Chemical-Grid quickly by providing a common language. It frees chemists to focus on problem-solving rather than on the details of various chemical scripting languages (CSLs) and the target runtime platform and associated middleware. UDLC jobs can directly invoke grid services without dealing with interaction with grid, such as job submission, job monitoring. Thus, it is interesting and meaningful for chemists to translate scripts in other CSLs to UDLC. The system architecture of the translators is presented, translation strategies and several key issues are discussed, and two specific translators are described in detail. The translators translating the scripts, especially a large number of well-tested scripts, to UDLC can help chemists carry out their research based on grid platforms.
