I was recently at an INTEL presentation in which this machine was
described.

The JPL DELTA is a large-scale version of INTEL's current iPSC
hypercube series using i860 RISC processors.  It is part of something
called the "Touchstone" project.  The Delta includes 528 i860 nodes
connected in a 2-D fashion.  It is said to achieve 32 GFlops peak
performance.  Processors operate in MIMD fashion with message-based
communication and a single process per node.  

INTEL is still evolving their system architecture.  Current iPSC
systems are hypercubes with i860s and possibly 386s combined and
usually no more than 32 - 64 nodes.  The DELTA system is a unique
installation.
