Workflows Community Summit

The workflowsRI and ExaWorks projects held a very productive Workflows Community Summit in January. The focus was to identify broad challenges for the workflows community and to propose a vision for community activities to address these challenges.

While the first summit focused on Establishing a high level vision, this second summit will explore technical approaches for realizing (part of) that vision. Consequently, we hope to engage participants who are actively involved in workflow system development.

Based on the outcomes of the first summit, we have identified four technical topics for discussion (some align with a single theme of the first summit, while others are cross-cutting):

1. Definition of common workflow patterns and benchmarks (both for determining workflow system functionality and for providing users with tutorial examples);
2. Identifying paths toward interoperability of workflow systems; and
3. Improving workflow systems' interface with legacy and emerging HPC software and hardware stacks
