ecflow

Workflow package that enables users to run a large number of programs

ecFlow is a client/server workflow package that enables users to run a large number of programs (with dependencies on each other and on time) in a controlled environment. It provides reasonable tolerance for hardware and software failures, combined with restart capabilities. It is used at ECMWF to run all our operational suites across a range of platforms. ecFlow submits tasks (jobs) and receives acknowledgments from the tasks when they change status and when they send events, using child commands embedded in your scripts. ecFlow stores the relationships between tasks, and is able to submit tasks dependant on triggers, such as when a given task changes its status, for example when it finishes.
