CSCS Blanc – IBM P5
This computer has been named after Mont Blanc in the French-Italian Alps, elevation 4807 m and his last configuration has been the follow:
- 48 nodes with 16 IBM Power 5
- 1780 GB DDR II Ram
- 40 TB Disk
- 10 GBit IB interconnect
Blanc started its life as production system on January 24th, 2007. This computer was another first of its kind. It was the first supercomputer based on Power 5 processors that runs Linux operating system using Infiniband as high-speed interconnect. This computer was another first of its kind. It was the first supercomputer based on Power 5 processors which run a Linux Operating System using InfiniBand high-speed interconnect.
Blanc was mainly used for high-memory jobs and for problems with limited scalability due to the size of the studied systems and the properties of interest.
The next photo depicts the interconnect of Blanc being based on InfiniBand.
