Below you can see a gallery that illustrate the computer room evolutions.
This was the situation at my arrival, in December 2010. The computer room contained around 120 computing cores (with different generations of CPU technologies) and no real storage capacity.
Before rebuilding the computer room, due to some problems of 3rd floor load resistance (more than 2.8T of computing materials in the room), we had slightly less than 1000 computing cores (868 in HPC clusters) and around 154TB raw for storage.
Before Lucifer cluster dismantling: 1828 CPU cores, ~108k GPU cores and around 750TB raw for storage (archive, home and workdir volumes).
In addition, in these new enclosures are hosted 3 virtualization clusters; one dedicated for LBT computation resources managment and the 2 others for Information Systems (one of which is shared with the IBPC).
As you can notice, everything is now black and white, proper and clean…
This is the current situation.
After Lucifer cluster dismantling: 972 CPU cores, ~115k GPU cores, ~3.2TB RAM and around 650TB raw for storage (archive, home and workdir volumes).
