Electron: A power budget manager
======================================

To Do:

 * Create metrics for each task launched [Time to schedule, run time, power used]
 * Have calibration phase?
 * Add ability to use constraints
 * Running average calculations https://en.wikipedia.org/wiki/Moving_average#Exponential_moving_average
 * Make parameters corresponding to each scheduler configurable (possible to have a config template for each scheduler?)
 * TODO : Adding type of scheduler to be used, to be picked from a config file, along with it's configurable parameters.
 * Write test code for each scheduler (This should be after the design change)
 * Some of the constants in constants/constants.go can vary based on the environment.  
   Possible to setup the constants at runtime based on the environment?
 * Log fix for declining offer -- different reason when insufficient resources as compared to when there are no
    longer any tasks to schedule.
 * Have a centralised logFile that can be filtered by identifier. All electron logs should go into this file.
 * Make def.Task an interface for further modularization and flexibility.

**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**


How to run (Use the --help option to get information about other command-line options):

`./electron -workload <workload json>`

To run electron with ignoreWatts, run the following command,

`./electron -workload <workload json> -ignoreWatts`
