Description
Requests for computing resources from LHC experiments are constantly
mounting, and so are their peak usage. Since dimensioning
a site to handle the peak usage times is impractical due to
constraints on resources that many publicly-owned computing centres
have, opportunistic usage of resources from external, even commercial
cloud providers is becoming more and more interesting, and is even the
subject of upcoming initiative from the EU commission, named
HelixNebula.
While extra resources are always a good thing, to fully take advantage
of them they must be integrated in the site's own infrastructure and made
available to users as if they were local resources.
At the CNAF INFN Tier-1 we have developed a framework, called dynfarm,
capable of taking external resources and, placing minimal and easily
satisfied requirements upon them, fully integrate them into a
pre-existing infrastructure and treat them as if they were local,
fully-owned resources.
In this article we for the first time will a give a full, complete
description of the framework's architecture along with all of its
capabilities, to describe exactly what is possible with it and what
are its requirements.
