They’re probably getting the PF number through their extrapolation program. They run one unit through the linpack, the use a program to extrapolate the results so they don’t have to bother running the long HPLs.

It's going to take some hefty programming to make this a usable machine for any thing beyond the specialized stuff ...

Consider that it’s going to the NNSA, I doubt if that will be a problem.

This will take some manpower to move to the Cell,...I would think:

SLATEC A Mathematical Library

eh---it's just FORTRAN. If the Cell processor has a FORTRAN compiler, it should just compile.

I don't don't about the availability of the compiler, though.

If you look at the architecture of the new Intel processors they are more akin to the Socket A AMD and the Mobile P3 processors...

C2D had to step backwards to where AMD and Intel had been there and done that...

Proving that Instructions per clock trumps final speed.

Intel rode that pony until it died...

had to look up NNSA:

National Nuclear Security Administration
From Wikipedia, the free encyclopedia

********************EXCERPT******************

The United States National Nuclear Security Administration (NNSA) is part of the United States Department of Energy. It works to improve national security through the military application of nuclear energy. The NNSA also maintains and improves the safety, reliability, and performance of the United States nuclear weapons stockpile, including the ability to design, produce, and test, in order to meet national security requirements.

NNSA has four missions with regard to National Security:

The NNSA maintains a database containing personal information on 37,000 persons who design and maintain nuclear weapons for the U. S. government.

The NNSA's Office of Secure Transportation (OST) provides safe and secure transportation of nuclear weapons and components and special nuclear materials, and conducts other missions supporting the national security of the United States of America. Since 1974, OST has been assigned responsibility to develop, operate, and manage a system for the safe and secure transportation of all government-owned, DOE or NNSA controlled special nuclear materials in "strategic" or "significant" quantities. Shipments are transported in specially designed equipment and are escorted by armed federal agents.

Intel's marketing Hype would have you believe that did miracles with the Core2....

AMD is still whopping them in the heavy duty heavy data moving department...know as the Server marketplace.

I'll bet this machine would be a big help to the FReeper folders.

Well duh!

How else to we keep the dust out of the core memory?

The PS3s being used to help achieve petaflop processing with Folding@Home kind of proved a system like this would be useful.

IBM XL Fortran for Multicore Acceleration for Linux on System p

A high-performance IBM XL Fortran compiler for the Cell Broadband Engine Processor.

So there is a compiler....for the Cell.

The Cell architecture

**********************EXCERPT********************

Single precision floating point computation is geared for throughput of media and three-dimensional graphics objects. In this vein, the decision to support only a subset of IEEE floating point arithmetic and sacrifice full IEEE compliance was driven by the target applications. Thus, multiple rounding modes and IEEE-compliant exceptions are typically unimportant for these workloads, and are not supported. This design decision is based the real time nature of game workloads and other media applications: most often, saturation is mathematically the right solution. Also, occasional small display glitches caused by saturation in a display frame is tolerable. On the other hand, incomplete rendering of a display frame, missing objects or tearing video due to long exception handling is objectionable.

I don't know what that means...any idea?
