Nowadays the workflow application is getting more and more popular to facilitate the grid user to solve complicated computing problems in the distributed resources. Due to the functional mismatch of the workflow management and resource management in the grid computing, we propose a new architecture of PQRM-based Pegasus workflow system, which is able to satisfy the grid workflow builder with SLA guarantees. The functionalities of each component in the integrated system will be specified in this paper as well as the algorithm realizing the SLA specification in the integrated model. Experiments are conducted to evaluate the performance under different SLAs and the discussion based on the trials will be followed at last.
