"Mouse brain simulated on computer", 27 April 2007, BBC NEWS
　http://news.bbc.co.uk/2/hi/technology/6600965.stm
"US researchers have simulated half a virtual mouse brain on a supercomputer."

"The three researchers, James Frye, Rajagopal Ananthanarayanan, and Dharmendra S Modha, laid out how they went about it in a very short research note entitled "Towards Real-Time, Mouse-Scale Cortical Simulations"."


で、調べてみたところ、元ネタは

でした。よく見ると 2月の発表です。

"We deployed the simulator on a 4096-processor BlueGene/L supercomputer with 256 MB per CPU. We were able to represent 8,000,000 neurons (80% excitatory) and 6,300 synapses per neuron in the 1 TB main memory of the system. Using a synthetic pattern of neuronal interconnections, at a 1 ms resolution and an average firing rate of 1 Hz, we were able to run 1s of model time in 10s of real time!"

表紙込みで 2ページ (a very short research note) です。

BBC NEWSで報道されると、宣伝効果はすごいですね。BBC NEWSを引用した記事が沢山あります。

あれ！、"SARC: Sequential Prefetching in Adaptive Replacement Cache"、"CAR: Clock with Adaptive Replacement"等々キャッシュアルゴリズムの方です。
IBM Almaden Research Centerで Cognitive Computingとは不思議でしたが。
