Rough Type: Nicholas Carr's Blog: The future of computing demand
February 09, 2007 Sun Microsystems has posted videos of its Analyst Day presentations from earlier this week. Following a tip from CEO Jonathan Schwartz, I watched CTO Greg Papadopoulos's presentation on the future of computing demand (pdf of slides). It's well worth a look. Papadopoulos shows that the traditional big driver of computing demand - basic business computing - has lost its force. The

There are currently two ways for AI models to learn things: training, and in-context during inference. Until now, training has dominated, because contexts are relatively short. But ultra-long context could change that. Instead of relying on fuzzy memorization, our LTM (Long-T

小規模企業がスーパーコンピューティングに注目
ゴルフクラブメーカーの米Pingは典型的なスーパーコンピューティングユーザーではない。航空機を作っているわけでもなければ、石油を探鉱しているわけでもなく、タンパク質を研究しているわけでもない。実際のところ、Pingはゴルフクラブの設計を手掛ける従業員1000名の会社だ。 だが、この中規模企業は、今後のスーパーコンピューティングの重要な役割を示しているのかもしれない。 PingはAMDのOpteronプロセッサを搭載するCrayのスーパーコンピュータを使って、ゴルフクラブの設計シミュレーションを行っている。同社スタッフエンジニアのエリック・モラレス氏によれば、スーパーコンピューティングのおかげで、同社は開発時間を大幅に短縮できている。Crayは今月に入り、Pingによる同社XD1システムの採用を発表した。XD1は12～800個のプロセッシングコアをサポートする。 「開発にかかる時間が数週間か

With CUDA 6, NVIDIA introduced one of the most dramatic programming model improvements in the history of the CUDA platform, Unified Memory. In a typical PC or cluster node today, the memories of the CPU and GPU are physically distinct and separated by the PCI-Express bus. Before CUDA 6, that is exactly how the programmer has to view things. Data that is shared between the CPU and GPU must be alloc

New vendor possible, but supercomputer could miss 2012 deadline | News-Gazette.com
CHAMPAIGN — Even with IBM pulling out of the Blue Waters project here, industry analysts say the leading-edge supercomputer could very well go on with another vendor — but quite possibly at a higher cost, and perhaps missing its fall 2012 deadline. The building, with its advanced water cooling system — expected to become an industry standard — as well as a massive electrical infrastructure, has be
The beginning of 2010 brought good economic news to Japan, which has seen only lackluster growth for the past two decades. Although the country's debt load and deflation remain serious problems, the world's second largest economy reportedly grew in the last quarter of 2009. But that does not mean that Japan is on a route to long-term recovery. Although the science budget for fiscal year 2011 was n
