Abstract: As scientific applications strive towards increasingly realistic modeling of complex phenomena, they are integrating multiple models and simulations into complex, coupled scientific workflows. As a result, ensuring that existing codes can be combined and recombined correctly and flexibly as part of these workflows is essential. In this presentation, I will discuss challenges in current methods for creating such compositions and propose a choreographic novel approach for creating in-situ scientific workflows, i.e., workflows that execute on a single extreme-scale system. Specifically, this approach involves providing a domain-specific abstraction that enables a programmer to instrument existing simulation codes so that they can be used as building blocks in defining complex workflows using a service-oriented approach. Using this approach, developers specify a workflow-level shared specification of data objects over common or partitioned data domains. This permits dependency-based execution to be specified at the workflow level, distinct from the independent operation of the component simulations. I will describe the features and benefits of this approach from the perspective of application design and systems optimization research.
