Analysis,design and application of grid-enabled execution environment for computing jobs

Regarding key issues in the execution process of scientific computing legacy codes,this paper made analysis and design.It proposed a grid-enabled execution environment for computing jobs based on "inherent computing runtime environment + grid runtime extension" to support execution of legacy codes.The proposed scheme was applied to the running of grid services wrapping scientific computing legacy codes.The proposed grid-enabled execution environment well satisfied requirements for runtime management of scientific computing legacy codes in grid environment and would see wide applicability and reference.
