Component API

TaskManager + HostManager

• scheduleTask(TaskDescriptor)
• terminate tasks
• list tasks (?), list hosts (?)
• receive task status updates
• accept task logs
• accept load info

HostRuntime

• receive execution commands (run, kill)
• list tasks on this host runtime
• report status
• pull SW dependencies
• relog task logs
• persist task data

Task Manager should not be a vital component, when it is not running, there will be a minimal "keep-alive" infrastructure in the cluster itself, which should keep the network operational and running.
