An x86 superscalar cluster water-cooled

Liger(*) is the largest and most capable computational resources available in the western french region, Pays de la Loire, for industrial and academics collaborators. A BULL’s superscalar x86 supercomputer performing a max performance (Rmax) of almost 200 Teraflop/s.

With it’s Direct Liquid Cooling System (DLC), Liger is the only cluster known in the region water-cooled and showed significantly more energy efficient than comparable systems, which is essential to control operating costs.

Partners access Liger, whether for open, publishable science or business-sensitive and proprietary research, through the High Performance Computing Institute of Centrale Nantes (ICI) . Partners gain access to one of the fastest Tier-2 regional class high-level HPC infrastructure available, including subject-matter experts, network access, file systems, archive storage, and training/help-line support.

The 10-rack Atos/BULL DLC system is based on the INTEL Xeon x86 architecture configured in a cube topology with a cold aisle confined.
