Blue Waters will be based on IBM's POWER7 architecture, which is based on advanced, multicore processor technology. It will:
* Be composed of more than 200,000 processor cores.
* Be capable of optimized simultaneous multithreading.
* Be capable of vector multimedia extension with four or more floating-point operations per cycle.
* Feature multiple levels of cache (private L1 and L2 caches for each core and an L3 shared cache).
* Provide 32 or more gigabytes of memory per SMP and 2 or more gigabytes of memory per core.
* Provide SMPs of 16 or more cores.
* Support 10 or more data streams.
* Provide an integrated network interconnect with significantly reduced latency and increased bandwidth. It will be able to overlap computation with I/O and node communication through RDMA technology.

They are currently building the IBM "Blue Waters" Petascale Computing Facility across the street from my office here in Illinois.
The building is almost finished and I think they are going to fire it up in September.
It cost $60 million to build, but ironically this state is billions in debt. (Thanks Blago!)
I'm not sure what the University of Illinois will use it for, but I do know my income taxes are going up 67% next year and social services are being slashed in half.
I dunno... I just think $60 million for a computer that can't play 'pong' is a little rich, especially when we have a lot of hungry unemployed folks here.
I will try to get the specs.
