Technologies are generally described for task management on computing platforms. In some examples, a method performed under control of a task management system may include determining a relationship among a plurality of tasks executed on a first platform to identify one or more associated tasks; identifying at least one attribute of each of the one or more associated tasks; generating a job that includes the one or more associated tasks and the identified at least one attribute of each of the one or more associated tasks; and instantiating, on a second platform, the one or more associated tasks included in the job based on the at least one attribute of each of the one or more associated tasks, in response to a request to launch the job.
