The "delta" referred to in the previous posting is formally

DARPA's  Touchstone Project, Delta Prototype.
It is a highly parallel machine, built by Intel, using i860 processors.

We have a Gamma prototype machine (one of two, the other went to Oak Ridge)
which is a preproduction version of what Intel Scientific is now selling as
the iSPC/860 - a cube architecture machine.  Ours has 128 i860 procs
and 8 or 10 386's for I/O.

The Delta machine is supposed to have 512 i860's, and a different routing
architecture (ie NOT a cube).  It is due to be delivered to JPL this 
spring.  We are supposed to get time on it, partly as comparison with the
Gamma.
