Introduction

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.

ecFlow runs as a server receiving requests from clients. The command-line interface (CLI), the graphical interface, scripts and the Python API (application interface) are the clients. The server is based on C++/boost ASIO and uses TCP/IP for communication. Multiple servers can be run on the same hardware. ecFlow submits tasks (jobs) and receives acknowledgements from tasks via specific commands embedded in the scripts. The relationship between tasks is stored in ecFlow, and it is able to submit tasks dependent on the status of other tasks and attributes like time.

The CLI for ecFlow allows the suite definition to be loaded and retrieved from the server. Also it provides a rich set of commands for communication with the server.

The Python API allows the entire suite definition structure to be specified and loaded into the server. A suite is a collection of interrelated tasks. In ecFlow suites are described by a definition file. The Python API also provides functionality for client to server communication. In addition, it allows checking of the suite, testing the defined interrelations between tasks, and other references and limits.

Programming language: C++
