Elektron: A Pluggable Mesos framework with power-aware capabilities
===================================================================

Elektron is a Mesos framework that behaves as a playground for developers to experiment with different scheduling policies to launch ad-hoc jobs.
Elektron is designed as a lightweight, configurable framework, which can be used in conjunction with built-in power-capping policies to reduce the peak power and/or energy usage of co-scheduled tasks.

#Features
* [Pluggable Scheduling Policies](docs/SchedulingPolicies.md)
* [Pluggable Power-Capping strategies](docs/PowerCappingStrategies.md)
* Cluster resource monitoring

#Software Requirements
**Requires [Performance Co-Pilot](http://pcp.io/) tool pmdumptext to be installed on the
machine on which electron is launched for logging to work and PCP collector agents installed
on the Mesos Agents**

Compatible with the following versions,

* Mesos 1.5.0
* Go 1.9.7

#Build and Run
Compile the source code using the `go build` tool as shown below.
```commandline
go build -o elektron
```
How to run (Use the --help option to get information about other command-line options):

`./elektron -workload <workload json>`

To run electron with Scheduling Policy Switching Enabled, run the following command,

`./electron -workload <workload json> -ssp -spConfig <schedPolicy config file>`
