NOTE: Pogo is a work in progress - watch this space for updates
Pogo is an agent-based system for running interruptive commands safely on thousands of machines in parallel.
Users request that a command (or recipe, or script) be executed on a group of target nodes by issuing new pogo jobs via the pogo(1) command-line utility. If the job is successfully created on the dispatcher, the user will receive a job id and a URL in response.
The pogo dispatcher then divides the job up into tasks, one task per target host. The dispatcher computes a task run order and distributes tasks to worker processes. Workers ssh to the target nodes and run the commands specified by the user, reporting progress and status back to the dispatcher.
