DrDr2 is a network of message passing servers.
- Monitor finds pushes and sends them to the scheduler
- The scheduler receives pushes, prepares a tar ball, and sends
jobs to the masters
- Each master sends commands to its slave and confirms to the scheduler
(so that it will receive more commands)
- The slave receives commands and executes them on a test machine
and sends the answer to the master
- The master receives the answer and sends it to the analyzer
- The analyzer records data for the renderer and informs the notifier
- The renderer queries the database
----
DrDr2 uses the MongoDB database for storage
DrDr2 is monitored using Monit
