Cluster Room history

For those who do not know me yet: my name is Geoffrey Letessier, I am the LBT IT manager (and 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 generations of CPU technologies), 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:

  • ERC Thermos (Fabio Sterpone)
  • ANR Exaviz (Marc Baaden)
  • IUF (Philippe Derreumaux)
  • ANR PEPS (Marc Baaden)
  • ANR NicoChimera (Marc Baaden)
  • ANR BioPac (Marc Baaden)
  • ANR MAPPING (Sophie Sacquin-Mora)
  • LBT laboratory's funds

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:

  • harmonized, homogenized and centralized the technical computing architecture
  • multiplied by 11 the number of cores; and many much more for computing power
  • grown up the storage system from 0 to roughly 700 TB raw

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 600k€.

Thanks to Fabio Sterpone to have been the iniator and the first investor for this project, quickly followed by Marc Baaden and Philippe Derreumaux. A couple of years later, Sophie Sacquin-Mora has joined the investor group.
