Off the top of my head, that sounds like Sandia Laboratories' ASCI
Option Red. A web search turned up :

  The Option Red system will contain 9000 Pentium Pro processors in 4500
   compute nodes with a theoretical peak performance of 1.8 Tflop/s. At
   this moment a measured performance of 1.068 Tflop/s has been realised
   out of 1.453 Tflop/s on 7264 processors ([4]) in the solving of a
   linear system of order 215,000. The system is of the DM-MIMD type with
   a network that resembles that of the Intel Paragon XP but at a higher
   speed: the point-to-point bandwidth has a maximum of 400 MB/s and the
   bisectional bandwidth of the full system should be 50 GB/s.

   The system harbours two cooperating operating systems: the Paragon OS,
   as used in the present Paragon machines and Light Weight Kernel system
   that should optimise task handling at the nodes.
