It introduces a domain-specific language that aims to provide simple but powerful facilities for (a) defining atomic units of computation (a task ), (b) for connecting those atomic units together into a larger computation graph (a workflow ), and (c) for effortlessly scaling the execution of these graphs in multiple environments. Most fundamentally, WDL differentiates itself from other workflow languages by focusing on ease of implementation and accessibility to a wide range of users, including software engineers, domain experts (e.g., biologists), and operators of production computational systems. Furthermore, idiomatic workflow execution patterns, such as conditional execution, dynamic resource allocation, and scatter-gather operations, are simply expressed. Last, the language is driven and developed by a community of distributed volunteers as an open standard; there is no single execution engine, and anyone can build tooling to contribute to the ecosystem. Today, [several engines and platforms] exist and cover most execution environments (all major HPCs, all major clouds, local execution). Join the community If you're new to WDL, welcome 👋.
