Google Summer of Code 2015

Here are our project ideas for Google Summer of Code 2015

It might be interesting to have a look at ideas in 2013 and 2014.

Project proposals

Improvements to the instance bin-packing tool (hsqueeze)

(language: Haskell) design

The hsqueeze tool is used to move virtual machines of a cluster to a subset of its physical machines, allowing to powering down the rest of physical machines to conserve energy.

Task: Make hsqueeze use the dynamic CPU data that is now collected thanks to previous summer of code projects.

Note: This project is well suited for someone who is already using hsqueeze or who cooperates with an organization that uses it.

Location awareness

(language: Haskell) design

Location awareness allows Ganeti to avoid common physical causes of failures when placing virtual machines on physical nodes.

Tasks:

• Improve the current implementation (i.e., finish implementing the design).
• Extends to more aspects of location.

Monitoring daemon

(language: Haskell)

The monitoring daemon collects information from physical machines of a Ganeti cluster.

Tasks:

• Implement data collectors for CPU (and maybe memory) usage for Xen-based clusters;
• possibly use this information for load-based cluster balancing.
• Add an interface for generic plugins that collect arbitrary user-defined data.
