Adaptive Workflow Evaluation

Chameleon

Adaptive workflow evaluation involves changing the way a workflow is being evaluated, for example which resources are being used, while the workflow is executing. Typically adaptation takes place with a view to improving performance or for fault tolerance.

Results in this area include a characterisation of adaptivity options and an adaptive extension to the Pegasus workflow infrastructure.
