NEC Strikes Back With SX-8 Supercomputer 192
News for nerds writes "It was just 3 weeks ago that we learned IBM's BlueGene/L with 36.01 TFlops edged out NEC's Earth Simulator, but today NEC announces a new SX-8 supercomputer with a peak processing performance of 65 TFlops (press release). It may be available in the U.S. as Cray's OEM like SX-6."

No, the original poster was saying that the 65TF number from NEC is theoretical peak performance based on the maximum possible number of FP operations per clock cycle (which can never happen in real code, due to pesky little things like having to access memory), while the ~35TF number for the Blue Gene/L prototype is measured performance on an actual piece of code called the Parallel Linpack benchmark. It's not unusual for systems to perform as low as 50% of peak on Parallel Linpack, although 70-90% is more typical on systems with decent memory bandwidth (which the SX8 presumably has).
(Note that I'm deliberately sidestepping the debate over whether Parallel Linpack bears any resemblence to reality.)

An equally important criticism is that they've only announced the POSSIBILITY of building a 65TF system. No one has actually ordered one. The cray X1 can scale up to 50TF if fully populated. The X1E scales up to 150TF. This is of no great consequence, as the largest one in production is only 10TF. Yes they could build a really big sx-8, but it cost $200M to build the earth simulator, probably something similar to build this thing.
There are a lot of computers that are really cool - on paper.

Re:65 TFlop is a good estimate! (Score:2)
The 65Tflops estimate is for 512 8 cpu nodes, which less then earth simulators.
Plus each of the cpus now has 16GFlops (and can archive it with that much memory bandwith it has), but uses less than half of the power of the old sx6.
So a "earth simulator 2" with 65TFlops would have 20% less cpus and 60% less power consumption then the first.
