Intel's Purley server based on Skylake in 2017


___________________________  
99% BAD HARDWARE WEEK: Knights Hill obviously in 2018. However, Groveport KNL will have integrated 2x100G OP Storm Lake fabric generation 1 ( generation 2 follows in Knights Hill ) . Purley server will support only 1x100G fabric you can see on a pic above. And new UPI instead of QPI. Why ? Well, recent Altera purchase wasn't money wasting. Altera FPGA chip close to SKL might use it ! You want IB connect, FPGA switch mode. Now, I want ethernet, ALtera  switch again. Even flash DIMMs aren't excluded. A lot of new, exciting oportunities.

By integrating the FPGA with the Xeon processor, we estimate that customers will see an additional 2X in performance thanks to the low latency, coherent UPI interface.
Facebook, Google and NSA too would like it. Intel already manufatures special server versions for them.

Oh by the way, OP means Optical-PCI (made by Fujitsu, Quanta) , and LBG? Larabee graphics! Groveport Platform is from official Intel revision 15.7.2014.

Intel's Skylake in August

SSDs lose data if left without power for just 7 days

Consumer class SSDs can store data for up to two years before the standard drops, but when it comes to SSDs used by enterprises, the drives are only expected to retain data for a period of three months – a fact confirmed by Samsung, Seagate and Intel's own ratings on their products.

EXCLUSIVE: Intel's Xeon Skylake ISA

___________________________  
99% BAD HARDWARE WEEK: CDI and AVX 512 F taken from forthcoming Knight Landing. Calculator ERI&PFI special instructions (sqrt and transc) remain inherently KNL's. Beside, it will use Storm Lake 100 Gbps integrated fiber optic fabric.  .
Storm Lake Gen 1 will support 2x100Gbps fiber optics, overall 50GB/sec fabric bandwith .
Aries interconnect routing chip, Intel has acquired from Cray in 2012, is able to support 16GBps. However, Intel's fiber optics failed for this year, so Storm Lake fabric support disappeared before Skylake Xeon announcement.

Boeing 787 Dreamliners contain a potentially catastrophic software bug


 "This condition is caused by a software counter internal to the GCUs that will overflow after 248 days of continuous power. We are issuing this AD to prevent loss of all AC electrical power, which could result in loss of control of the airplane."

AIRBUS HAS acknowledged that the reason its A400M military plane went down in Spain on 19 May was down to incorrectly configured software rather than a hardware failure.Software glitches had already cost the project three years and put it seriously over budget, but it was assumed that the problems had been resolved.
