Task Execution Service (TES)
TES is a GA4GH Cloud Work Stream standard for a RESTful API that submits, manages, and monitors batch computational tasks. It was developed to make large-scale genomic analyses portable across compute environments — but the contract is general-purpose: any batch workload that fits "run this command with these inputs and collect these outputs" is in scope.
A TES task declares:
- A sequenced list of
executors(image + command + env + workdir). - Optional
inputs(URLs to stage onto a shared volume). - Optional
outputs(paths to upload after the executors run). resources(CPU, RAM, disk).
The server schedules execution and reports back state, per-executor logs, and termination reasons. Poiesis implements the server side on Kubernetes.
