Service Level Agreements (SLAs) is currently one of the major research topics in grid computing. Among many system components for the SLA-related grid jobs, the SLA mapping mechanism has received wide spread attention. It is responsible for assigning sub-jobs of a workflow to a variety of grid resources in a way that meets the user's deadline and costs as little as possible. With the distinguished workload and resource characteristics, mapping a heavy communication workflow within an SLA context gives rise to a complicated combinatorial optimization problem. This paper presents the application of various metaheuristics and suggests a possible approach to solve this problem. Performance measurements deliver evaluation results on the quality and efficiency of each method.

Abstract. In the business Grid environment, the business relationship between a customer and a service provider should be clearly defined. The responsibility of each partner can be stated in the so-called Service Level Agreement (SLA). In the context of SLA-based workflows, the business model is an important factor to determine its job-resource-mapping policy. However, this aspect has not been described fully in the literature. This paper presents the business model of a system handling SLA-based workflow within the business Grid computing environment. From this business model, the mapping policy of the broker is derived. The experiment results show the impact of business models on the efficiency of mapping policies. 1

Abstract. Service Level Agreements (SLAs) are currently one of the major research topics in Grid Computing. Among those system components that support SLA-aware Grid jobs, the SLA mapping mechanism has an important position. It is responsible for assigning sub-jobs of the workflow to Grid resources in a way that meets the user’s deadline and minimizes costs. Assuming many different kinds of sub-jobs and resources, the process of mapping an SLA-based workflow with light communication defines an unfamiliar and difficult problem. This paper presents a solution to this problem. The quality and efficiency of the algorithm is validated through performance measurements. 1

Service Level Agreements (SLAs) is currently one of the major research topics in Grid Computing. Among many system components for the supporting of SLA-aware Gridbased workflow, the SLA mapping module receives important positions. Optimizing execution time is an important task of the mapping module as it helps in finding out a feasible solution when the Grid is busy or by eliminating the negative effects of the error. With the previously proposed algorithm for optimizing the execution time of the workflow, the mapping module may, when many requests come in a short period of time, become the bottleneck of the system. This paper presents a parallel mapping algorithm for optimizing the execution time of the workflow, which can cope with the problem. Performance measurements deliver evaluation results on the quality of the method. 1.

Service Level Agreements (SLAs) are currently one of the major research topics in Grid Computing. Among many system components for supporting of SLA-aware Grid-based workflows, the SLA mapping module receives an important position. Mapping light communication workflows is one main part of the mapping module. With the previously proposed mapping algorithm, the mapping module may become the bottleneck of the system when many requests come in a short period of time.

Service Level Agreements (SLAs) are currently one of the major research topics in Grid Computing. Among many system components for supporting of SLA-aware Grid jobs, the SLA mapping module holds an important position and the capability of the mapping module depends on the runtime of the mapping algorithm. With the previously proposed mapping algorithm, the mapping module may develop into the bottleneck of the system if many requests come in during a short period of time. This paper presents a parallel mapping algorithm to map heavy communication SLA-based workflow onto Grid resources which can cope with the problem. Performance measurements thereby deliver evaluation results showing the quality of the method. 1.
