For those who do not know me yet: my name is Geoffrey Letessier, I am the LBT IT manager (in the fact, the only one IT staff member) and my office is located at the IBPC third floor (door #328).
At my arrival in lab, in December 2010, the computing resources was only composed by roughly 120 cores (with different CPU technologies and generations), and the room by a few old servers and around 25 desktop machines, completely partitioned (and without any centralized management service).
After a few months, some PIs asked me to think about a new computing architecture to significantly improve the computing and storage capabilities and performance. This was the origin of Hades cluster (2011-2012), closely followed by Lucifer (2013-2014) and Baal (initiated in 2015) ones.
Hereafter, the various budget sources that enabled this breakthrough:
On the next illustration, you can see the current computing room organigram.
Thereby, in a few years and only concerning the LBT's computing resources, we have:
That said, we have to keep in mind that the needed investment budget (for computing room rehabilitation and modernization) has been mainly apportioned for the first 4-5 years and is currently of around 750k€.
Thanks to Fabio Sterpone to have been the instigator and the first investor for this project, quickly followed by Marc Baaden and Philippe Derreumaux. A couple of years later, Sophie Sacquin-Mora, Jérôme Hénin, Labex Dynamo and Guillaume Stirnemann joined the group of investors.
