Specification and Runtime Workflow Support in the ASKALON Grid Environment
Radu Prodan · Scientific Programming · 2007
We describe techniques to support the runtime execution of scientific workflows in the ASKALON Grid environment. We present a formal model and three middleware services that support in combination the effective execution in heterogeneous and dynamic Grid environments: performance prediction, scheduling, and enactment engine. We validate our techniques with concrete experimental results for two real‐world applications executed in the Austrian Grid environment.
