The T90 is a vector supercomputer. The T3D and
T3E are not.

Indeed. The next generation Origin, refered to as SN-1, will
be a joint SGI/Cray design and will replace the T3E as well.

2 machines (at least!!) have already been ordered - the DOE
ASCI Blue Mountain project. See
lanl.gov
1 is a 3072 processor machine, the other is 1024.

(I am assuming that these will be SN-1, rather than SN-2,
from the timescale involved - maybe some of the Cray people
on this thread can confirm if this is correct, thanks).

SN-2 will replace the vector machines (J90 & T90) as well
as SN-1.

Along the way, a lot of OS functionality will be added to IRIX
from Unicos, such as DMF announced this week.

Ed

PS: IMHO buying Cray is one of the best things SGI ever did -
even just for the OS technology, never mind the hardware
expertise.

They aren't. They use generic Alpha processors; compared to the Origin, they have a less scalable interconnect, but one which physically/electrically scales well to over 2000 processors, and a latency-hiding subsystem between memory better tuned to the typical 'embarassingly parallel' jobs you might want to run on it, which one may call more vector-like.

The J90 and C90 are Vector (super)computers.
