Rur Valley Journal: What's Up at Jülich?
By Josh Simons on May 29, 2009
What's up at Jülich? The latest 200+ TeraFLOPs of Sun-supplied HPC compute power is now up and running!
The JuRoPa (Jülich Research on PetaFLOP Architectures) system at the Jülich Research Center in Jülich, Germany has just come online this week. A substantial part the system is built with the Sun Constellation System architecture, which marries highly dense blade systems with an efficient, high-performance QDR InfiniBand fabric in an HPC cluster configuration.
We delivered 23 cabinets filled with a total of 1104 Sun Blade x6275 servers or 2208 nodes. Each of these nodes is a dual-socket Nehalem-EP system running at 2.93 GHz. The systems are connected with quad data-rate (QDR) 4X InfiniBand using a total of six of our latest 648-port QDR switches. As usual, we use 12X InfiniBand cables to route three 4X connections, thereby greatly reducing the number of cables and connectors, and increasing the reliability of the fabric. For more detail on the Nehalem-EP blades and other components used in this system, see this blog entry.
I've annotated one of the official photos below. Marc Hamilton has many more photos on his blog, including some cool "underground shots" at Jülich.
