A Performance Model for Federated Grid Infrastructures

Abstract

A performance model, previously proposed to characterize the performance of grid infrastructures, is extended to evaluate federations of grids by aggregating their performance parameters. These parameters can then be used to develop scheduling policies based on them. The new model can be used to take scheduling decisions based on them and hence to aid in the development of scheduling policies. The model has been validated using the performance results obtained in the execution of a high throughput computing application on an enterprise grid composed of Globus Toolkit Web Service resources and a GridGateWay giving access to gLite resources from the EGEE infrastructure.

“…With every completed job, the algorithm recalculates the performance of the individual Grid infrastructure where it was executed, by updating its r ∞ and n 1/2 values 5. Finally, to characterize the performance of the whole Federated Grid, we use an aggregation or federation model 7. This allows us to calculate the objective or number of jobs to submit to each of the participating Grid infrastructures using integer linear programming.…”

A decentralized model for scheduling independent tasks in Federated Grids

“…The linear relation represented by Equation 1 can be used to define the performance of each grid infrastructure forming the Federated Grid (tasks completed per second), the aggregation or federation model [48] is then used to determine the Objective even in case of having more than two participants.…”

“…A real infrastructure has previously been set up [48,47] and allows resources from the EGEE infrastructure to be accessed through a GridGateWay. However, the deployment of the proposed algorithms on a real environment will require involvement of a large number of active users and resources, which is very hard to coordinate and build, and would prevent repeatability of results.…”

Dynamic Objective and Advance Scheduling in Federated Grids

“…The linear relation represented by Equation 1 can be used to define the performance of each grid infrastructure forming the Federated Grid (tasks completed per second), then by using the aggregation or federation model [16] we can determine the Objective even in case of having more than 2 participants.…”

“…We have previously [16,17] set up a simple, but real infrastructure, where resources from the EGEE infrastructure are accessed through a GridGateWay. However, prior to run DO-AS on a real production infrastructure, we have first implemented it on a simulated environment.…”
