Multi-objective Optimization of Clustering-based Scheduling for Multi-workflow On Clouds Considering Fairness [PDF]
arXiv, 2022 Distributed computing, such as cloud computing, provides promising platforms to execute multiple workflows. Workflow scheduling plays an important role in multi-workflow execution with multi-objective requirements. Although there exist many multi-objective scheduling algorithms, they focus mainly on optimizing makespan and cost for a single workflow ...

The bi-objective workflow satisfiability problem and workflow resiliency [PDF]
Journal of Computer Security, 2016 A computerized workflow management system may enforce a security policy, specified in terms of authorized actions and constraints, thereby restricting which users can perform particular steps in a workflow. The existence of a security policy may mean that a workflow is unsatisfiable, in the sense that it is impossible to find a valid plan (an ...

Bounded and Approximate Strong Satisfiability in Workflows [PDF]
arXiv, 2019 There has been a considerable amount of interest in recent years in the problem of workflow satisfiability, which asks whether the existence of constraints in a workflow specification makes it impossible to allocate authorized users to each step in the workflow.

Using Cloud-Aware Provenance to Reproduce Scientific Workflow Execution on Cloud [PDF]
, 2015 Provenance has been thought of a mechanism to verify a workflow and to provide workflow reproducibility. This provenance of scientific workflows has been effectively carried out in Grid based scientific workflow systems. However, recent adoption of Cloud-based scientific workflows present an opportunity to investigate the suitability of existing ...
