There’s a shake-up – and a scandal – in the Top500 ranking of the world’s most powerful supercomputers.
The U.S. has retaken first place in the Top500 list after five years of dominance by China. Computers built by IBM for the U.S. Department of Energy have pushed the previous two record-holders, both Chinese, into second and fourth place.
But the previous fourth placeholder, Japan’s Gyoukou, is nowhere to be found, after one of its creators was arrested on suspicion of fraud.
The team designing Oak Ridge National Laboratory's new Summit supercomputer correctly predicted the rise of data-centric computing – but its builders couldn't forecast how bad weather would disrupt the delivery of key components.
Nevertheless, almost four years after IBM won the contract to build it, Summit is up and running on schedule. Jack Wells, Director of Science for Oak Ridge Leadership Computing Facility (OLCF), expects the 200-petaflop machine to be fully operational by early next year.
"It's the world's most powerful and largest supercomputer for science," he said.
Spreading bad routing information to your neighbors on the internet isn’t just bad manners, it could be bad for business.
That, at least, is the message that the Internet Society (ISOC) wants to spread, as it calls on internet exchange points (IXPs) to help eliminate the most common threats to the internet’s routing system.
If they do so, then it’s good news for their members, the ISPs that interconnect there, and for those ISPs’ customers, who will benefit from more secure and robust internet access.
IBM正在扩大其大型机范围内具有一些窄模型 - ZR1和跳岩II - 是瘦足以安装在一个标准的19英寸机架，这将回答的潜在批评客户在2017年太大7月推出的笨重Z14以适应他们的数据中心（见上面的照片）。
除了新的，更小，包装以其Z14硬件，IBM还推出了安全服务容器雷竞技电脑网站技术。这使得使用Z14的加密加速器和其他安全功能来保护集装箱化应用免受不必要的干扰。 <抛开类=“fakesidebar”> [查看的REVIEW: VMware’s vSAN 6.6 and hear IDC’s top 10 data center predictions . | Get regularly scheduled insights by signing up for Network World newsletters. ]
When IBM introduced the z14 last July, with an accelerator to make encrypting information standard practice in the data center, there was one problem: The mainframe's two-door cabinet was far too deep and too wide to fit in standard data center aisles.
