Cray announced first Rainier supercomputer

Here is supercomputer November 2006 share by processors used:
Processor Family Count Share % Rmax Sum (GF) Rpeak Sum (GF) Processor Sum
Power 91 18.20 % 1204808 1611805 416492
Cray 4 0.80 % 37377 44557 2538
Alpha 3 0.60 % 22323 31632 13768
PA-RISC 20 4.00 % 63786 119950 30708
Intel IA-32 119 23.80 % 445329 797653 131162
NEC 3 0.60 % 47697 53248 5888
Sparc 3 0.60 % 16818 35009 5440
Intel IA-64 35 7.00 % 316934 374798 60862
Intel EM64T 109 21.80 % 605876 1026853 123982
AMD x86_64 113 22.60 % 766661 1118476 230061
Totals 500 100% 3527609.06 5213980.18 1020901


100 teraflops by the end of this year, and again to 250 teraflops in 2007 or early 2008.
So why is Opteron role important there? 100 Tflops currently releases a lot of heat.
Just released, code named Hood supercomputer at NERSC consists of over 19,000 AMD Opteron 2.6-gigahertz processor cores, with two cores per socket making up one node. Each node has 4 gigabytes (4 billion bytes) of memory and a dedicated SeaStar connection to the internal network. The full system will consist of over 100 cabinets with 39 terabytes (39 trillion bytes) of aggregate memory capacity.
The Cray XT4 supercomputer is the first product in Cray's Rainier program.

The Cray XT4 supercomputer uses up to 30,000 AMD Opteron dual-core processors running a highly scalable operating system and interfaced to the Cray SeaStar2™ interconnect chip.
Just as predicted by badhardware.
