ZT:意法半导体决定购买龙芯2E生产和全球销售权 发着玩 |

中国科学院计算技术研究所所长李国杰院士日前指出，作为中国自主创新的品牌，龙芯2以其低功耗、低成本的优势，将成为“穷人的CPU(中央处理器)”。
CPU(中央处理器)是计算机的“心脏”。长期以来，通用中央处理器市场被极少数跨国公司所垄断。
李国杰是在向前来中科院视察知识创新工程的全国政协委员们介绍龙芯CPU的产业化前景时作上述表示的。李国杰说：“龙芯2的优势是低功耗，只有3瓦，而一般CPU芯片功耗为20瓦至100瓦，其次是低成本，因此龙芯2是穷人的CPU，主打‘经济适用计算机’和高端嵌入式市场。”
据李国杰院士介绍，龙芯2E在法国流片成功以后，在全世界排名第五的集成电路生产厂商——意法半导体公司决定购买龙芯2E的生产和全球销售权。今年6月，中科院计算所和意法半导体公司签订技术许可协议，该公司计划每年销售龙芯芯片1000万片以上。
“这改变了长期以来我国在信息领域只有从国外引进核心技术的局面，第一次向国外大公司有偿发售CPU核心技术的使用许可，这是近年来计算所自主创新成果产业化的突出成绩。”李国杰院士指出，龙芯有可能先在国外打响。
据了解，龙芯是中国科学家自主研制的通用处理器，这改写了我国无“中国芯”的历史。“十五”期间，中科院计算所在863计划支持下，继2002年研制成功龙芯1号处理器芯片后，近年分别研制成功龙芯2的不同型号——龙芯2B、龙芯2C、龙芯2E，每个芯片的性能都是前一个芯片的3倍，实现了通用处理器设计的跨越发展。

DDR3的马甲:P 其实是DDR2拉 |

HOW DOES PI in 17 or 18 seconds sound? Well,
that's what we got with FLEXX PC2-9200 memory
overclocked to 1280MHz.
We wrote about this memory last Friday here
and this is what we achieved over the
weekend.
We used Intel Core 2 Duo E6700 CPU at its
default 2.66GHz and got 18 seconds and, once
you overclock the FSB, you can get seventeen. The FSB on the screenshot worked at 1066
while we used 5-5-5-18 memory settings.
The best of all is that it doesn’t need
water or air cooling. We increased the
voltage to 2.4 V - still covered by OCZ's lifetime warranty - and the machine was
stable at even 1280MHz. We are not aware that
anyone got more than 1200 before.
With water cooling or active fan maybe we can
go even more than that but this is what we managed. Even the PI at 32MB was stable with
2.4 voltage and 1280MHz settings.
Stay tuned the full-scale review and much
more scores coming shortly but till then
enjoy the screen shots.

转:IBM与洛斯阿拉莫斯国家实验室合作研发超级FWQ |

IBM has won a bid to build a supercomputer called Roadrunner that will include not just conventional Opteron chips but also the Cell processor used in the Sony Playstation, CNET News.com has learned. The supercomputer, for the Los Alamos National Laboratory, will be the world's fastest machine and is designed to sustain a performance level of a "petaflop," or 1 quadrillion calculations per second, said U.S. Sen. Pete Domenici earlier this year. Bidding for the system opened in May, when a congressional subcommittee allocated $35 million for the first phase of the project, said Domenici, a Republican from New Mexico, where the nuclear weapons lab is located.
Now sources familiar with the machine have said that IBM has won the contract and that the National Nuclear Security Administration is expected to announce the deal in coming days. The system is expected to be built in phases, beginning in September and finishing by 2007 if the government chooses build the full petaflop system.
There's plenty of competition in the high-end supercomputing race, though. Japan's Institute of Physical and Chemical Research, called RIKEN, announced in June that it had completed its Protein Explorer supercomputer. The Protein Explorer reached the petaflop level, RIKEN said, though not using the conventional Linpack supercomputing speed test.
Representatives of IBM and Los Alamos declined to comment for this story. The NNSA, which oversees U.S. nuclear weapons work at Los Alamos and other sites, didn't immediately respond to a request for comment.
Hybrid supercomputers
The Roadrunner system, along with the Protein Explorer and the seventh-fastest supercomputer, Tokyo Institute of Technology's Tsubame system built by Sun Microsystems, illustrate a new trend in supercomputing: combining general-purpose processors with special-purpose accelerator chips.
"Roadrunner is emphasizing acceleration technologies. Coprocessor acceleration is intrinsic to that particular design," said John Gustafson, chief technology officer of start-up ClearSpeed Technologies, which sells the accelerator add-ons used in the Tsubame system. (Gustafson was referring to the Roadrunner project in general, not to IBM's winning bid, of which he disclaimed knowledge.)

龙芯盒子要开始预购了!!! |

关于预购
周一安排下去准备，由于市场部门还没有经验，要求做的一些优惠措施和返款计划没有及时做出来，另外原本打算在论坛开一个专区供发表认购贴，但是后来也考虑到认购贴需要各位提供一些详细个人情况，也许有人不希望在网上公开；所以想专门做一个认购网页，这也是推迟的原因之一。
这里我们先给出基本价格和一个临时的预购方法：
1. 配置。这个在论坛上应该大家已经比较熟悉了，666M Godson-2E CPU(如果北桥能够稳定上75M，考虑考虑以750M提供），40G硬盘，256M DDR内存。会有产品说明书，软件光盘和一些小附件（考虑为首批机器定制一个小礼品）。暂时只售主机，没有显示器和键盘鼠标。
2. 价格。目前初定销售价为1599元，对在机器测试和软件开发上做出贡献的，可以根据情况部分或者全部退款。具体措施在制定中。在校的学生可以向公司申请延期付款，争取用自己的贡献抵扣货款。在开发者乐园版已经发布了一个供参考的软件任务列表。其中硬盘和内存可以根据您的要求替换或者不配。
3. 想要购买龙梦盒子的同志们请发送邮件到 sales@lemote.com。请留下您的真实姓名，联系地址，基本背景（学生/员工，从事行业等)，以及您的要求和建议。
另外，还有一点请大家理解：龙梦盒子目前是在中试推广阶段，难免还存在一些小问题，因此我们以低于成本价出售，对购买人也会进行一定的考察。
让我们一起把龙芯电脑做得更好！
BTW: 这两天公司开内部总结会，没有及时向大家说明，特致歉意。
