No. The bottleneck in a setup like this is the centralized wireless controller chipset architecture that routes all of the data coming in and out. Proxim's solution, instead, uses a new distributed wireless architecture for which enables it to smartly share the burden over the two radios. It uses two standard Atheros 802.11n radio chips and a controller processor from Freescale. This is also different from the many dual-band routers out there that use two radios, but only for each band individually—not combined into a single bandwidth pipe.
Of course, your computer only has one radio, so you won't see double the speeds on your local machine. This just helps cram more data onto a huge enterprise network without bringing it down, but an interesting strategy that could, theoretically, find its way into more consumer-type gear. The dual-radio AP-8000 costs $1,099, and also looks like a Dungeness crab after I've eaten four delicious legs already. Sold! [Product Page via GigaOM]
Both the IBM and Cray systems break the petaflop processing barrier according to Top500 measurements (1.45 petaflops vs 1.38 petaflops, respectively). Heck, even IBM admitted to us that the two computers "run neck and neck." But there's a huge difference between them.
The Roadrunner uses roughly half the power of the Jaguar XT.
It assembles 12,960 IBM PowerXCell 8i Cell Broadband Engine processors and an additional 6,948 AMD Opteron Dual-Core processors. The AMD equipment handles "basic" functions while the IBM chips handle the intense number crunching. (Read all about the Roadrunner here.)
Seeing as the Cray XT5 uses 45,000 quad-core AMD Opteron processors to get the same job done, you've gotta be at least a little impressed. [Top500]
According to SGI, the key to make this system work is their proprietary Kelvin cooling technology, which we can only imagine works by pouring buckets of liquid nitrogen over the CPUs. According to them, all this vaporware may result in a computer that can sustain 20,000 threads of execution, with a 15TB/sec memory bandwidth per rack.
• High concurrency with 20,000 threads of execution — 40 times more than a single rack x86 cluster system
• High throughput with 15TB/sec of memory bandwidth per rack — over 20 times faster than a single rack x86 cluster system
• Greater balance with up to three times the memory bandwidth/OPS compared to current x86 CPUs
• High performance with approximately 3.5 times the computational performance per rack
• Greener with low-watt consumer CPUs and low-power memory that deliver 7 times better memory bandwidth/watt
• Innovative Silicon Graphics Kelvin cooling technology, which enables denser packaging by stabilizing thermal operations in densely configured solutions
• Operating environment flexibility, capable of running industry-standard Linux(R) implementations, with Microsoft(R) Windows(R) variants on some configurations
