# CLUES

**CLUES (CLUster Energy Saving) INDIGO Extensions**

[CLUES](https://github.com/grycap/clues) is an elasticity manager system for HPC clusters and Cloud infrastructures that features the ability to power on/deploy working nodes as needed (depending on the job workload of the cluster) and to power off/terminate them when they are no longer needed.

CLUES has been extended in the INDIGO-DataCloud project with new plugins to support the [PaaS Orchestrator](https://github.com/indigo-dc/orchestrator) and to introduce elasticity capabilities to both HTCondor and Apache Mesos (including its frameworks Chronos and Marathon). These are the plugins:

* indigo\_orchestrator.py: CLUES plugin to connect with the INDIGO orchestrator.
* condor.py: CLUES plugin to connect with HTCondor.
* mesos.py: CLUES plugin to connect with Mesos, Chronos, and Marathon.
