Most users have a 'workflow', a set of steps they take to execute their applications and generate and interpret results. What happens when a workflow becomes large and complex? Workflow management tools are designed to meet this challenge. ALCF supports multiple tools that can help users:
- execute large numbers of independent tasks
- manage the import or export of data for tasks
- coordinate the execution of dependent tasks
- orchestrate dynamic workflows that incorporate ML or AI models
This seminar will discuss tools used at ALCF and show examples of how these tools can be used on Polaris.
