  2. Outline • Whyweuseworkflows? • Jobs • Workflows • Complexworkflows • SomeRestrictions

  3. Why we use workflows? • Make execution process be modularized • Parallelization possibilities • Large data manipulation

  4. Jobs • Singlenodesthatshould be executedto a WN (finally) • Itcontains: • Binary (orreferencetoit) • Inputs (orreferences) • Outputs(orreferences) • Requirements (for hardware, installed software stack …)

  5. Workflows • Nodes connected by abstract data-transfer • A graph structure • Most of them are DAG (directed acyclic)

  6. Complex workflows • Possibilities of parallelism:

  7. In general that’s all! • Thank you!
