PROOF (the Parallel ROOT Facility) is a framework distributed with ROOT that allows to run interactive analyses in a parallel and distributed fashion.
PROOF is available in three different flavours:
- Virtual Analysis Facility: run your personal PROOF cluster on the cloud (like CERN's OpenStack) by launching zero-configuration CernVM virtual machines
- PROOF-Lite: exploit muliticores by running an analysis in parallel on your desktop or laptop
- PROOF with PoD (PROOF on Demand): run analysis on a distributed cluster by submitting workers either on a batch system or via SSH
