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
• Pluggable Power-Capping strategies
• Cluster resource monitoring

#Software Requirements Requires Performance Co-Pilot 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.

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>
