A press release from the Argonne Leadership Computing Facility talks about their new machine “Eureka” from Graphstream.

The ALCF’s ability to visualize such enormous quantities of data is made possible by of the world’s largest graphics processing units (GPU). Nicknamed Eureka, this installation of NVIDIA Quadro Plex S4 external GPUs allows researchers to better understand the data they produce with Intrepid at the ALCF. The powerful installation provides more than 111 teraflops and more than 3.2 terabytes of RAM.

Eureka has some interesting hardware features including a special configuration of Quadro Plex S4’s, a nine-switch  2048-connection network interconnected, and a special bank of 10,000 disk drives all packed into 4 racks.
