The unprecedented growth in networked edge devices (e.g., scientific instruments, sensors) has caused a data deluge in scientific application communities. The data processing is increasingly relying on distributed computing to cope with the heterogeneity, scale, and velocity of the data. At the same time, there is an abundance of low-cost computation resources that can be used for “volunteer edge-cloud computing” (VEC), where collaborators in a community (e.g., bioinformatics, manufacturing) contribute their resources to form a distributed infrastructure to execute scientific workflows. In this talk, a VEC management reference architecture and a related framework implementation will be presented for support of trusted resource allocation in VEC environments for scientific data-intensive workflows. We demonstrate how our novel scheduling approach optimizes task allocation on VEC nodes by balancing workflow requirements and resource preferences, improving latency, task completion times, and resource utilization efficiency. Lastly, we outline our recent efforts to ensure privacy-preservation of the scientific workflow execution in VEC environments by adopting principles from the confidential computing paradigm.
