The Btrplace Sandbox

The VM placement algorithm inside Entropy is no longer a child and it deserves its own name now: Btrplace.

To celebrate this announcement, I have developed a sandbox that allows users to play with the algorithm on a simulated datacenter directly from the browser. It's simple, it's fun and it is available here.

This sandbox has been realized in the context of the FUI openCloudware project. This project aims at building an open software engineering platform for the collaborative development and deployment of distributed applications.

Back from TridentCom 2012

Hi

I just went back from the 2012 edition of TridentCom.

The conference was great with very interesting papers and a lot of demos. The swimming pool was nice too :D.

Icing on the cake, the paper I made with Robert Ricci get the best paper award. On my publications page, you can now have an access to the author copy of the paper and the slides I presented during the conference.

Entropy + Fit4Green = ♥

Fit4Green is a project that is funded by the Commission of European Union. It's main goal is to reduce the direct energy consumption of ICT resources of a federation of data centres.

Since mid 2011, the resource optimizer of the Fit4Green prototype relies on the plan module of Entropy, called BtrPlace, to compute the VM placement and the server state according to various green concerns.

A research paper describing their work has been accepted to the E-energy conference. The author version of the paper is available on my publication page, or directly here.

CSI - Salt Lake City: How To Build a Better Testbed

During my postdoc at Flux. I have analysed the usage of Emulab since its creation. With Robert Ricci, we used these informations to try to improve the testbed design with regards to its real usage rather than assumptions. The result of this investigation has been accepted to the TridentCom 2012 conference.

If you always wanted to see a crime scene, the paper is available from my website or directly here.
