Bitcoin plunges 20% from its high
From Wednesday’s high of more than $11,000 bitcoin has fallen to $9,021.85, a roughly 20 percent drop. Bitcoin last traded at $9,328.25 on Thursday, down 4.9 percent, according to CoinDesk. “I would say that you’ve seen several important, pretty severe corrections to bitcoin over time and it’s managed to come back,” Mark Newton told CNBC on Thursday. “From a percentage standpoint, the volatility isn’t that different than what you’ve seen in August.”…

US ‘orchestrated’ Russian spies scandal, says Kaspersky founder

US ‘orchestrated’ Russian spies scandal, says Kaspersky founder
Mr Kaspersky claimed at a press conference that previous media coverage of the company ‘mixed the truth and non-truth’ to give a misleading impression of its relationship to the Russian government. Eugene Kaspersky, chief executive and co-founder of the embattled Russian cybersecurity firm that bears his name, believes his company is at the centre of a “designed and orchestrated attack” to destroy its reputation. Over a short period in the summer of 2017, Kaspersky Labs was the subject of multiple media reports alleging that the company had helped Russian intelligence agencies spy [ of course fake news ] on the US, a number of FBI raids on staff members, and a nationwide ban on the use of its software by federal government agencies [ they are too good for their own safety ]…

Apple is designing its own power management chips for iPhones, and plans to stop relying on its current supplier Dialog Semiconductor, anonymous sources told Nikkei Asian Review. One anonymous source said: “Based on Apple’s current plan, they are set to replace around half of its power management chips to go into iPhones by itself, starting next year.” Another person said the chips might not be ready until 2019…

[ From Linley Newsletter ] entriq Aces Scale-Out Performance

[ From Linley Newsletter ] entriq Aces Scale-Out Performance
Qualcomm has its head in the clouds, but in a good way. Early benchmarking indicates its new Centriq server processors deliver excellent scale-out performance for cloud applications and data centers. Although the company’s ARMv8-compatible CPUs can’t match the per-core throughput of the best x86 CPUs, they rank high in throughput per thread, per watt, per dollar, and per square millimeter of silicon. These metrics translate into bargain prices for competitive performance and power consumption — and a strong debut for a newcomer to the nearly impregnable server-processor market.
By Tom R. Halfhill
The Centriq 2400 family (code-named Amberwing) initially comprises three models based on the same die: the 48-core 2460, the 46-core 2542, and the 40-core 2434. Clock frequencies hover within a narrow range (2.2-2.3GHz base, 2.5-2.6GHz turbo), as do the power ratings (110-120W TDP). List pricing, however, varies from $1,995 to a surprisingly low $888 — posing a credible challenge to Intel and AMD in view of Centriq’s competitive SPEC scores.
One observation is that Centriq offers relatively little differentiation within the family. Indeed, we suspect most customers will bypass the 48-core 2460 in favor of the 46-core 2452, which delivers 97% of the performance for only 69% of the price. And the 46- and 40-core chips differ in throughput by only 13%. The low-end 2434 offers a phenomenal deal in performance per dollar. Although Centriq falls short of the highest-end AMD and Intel products in peak performance, it matches well against mainstream models.
Centriq chips are shipping in limited volume this quarter and are ramping production. That Qualcomm is underpricing Xeon Scalable processors is no surprise, but Centriq also offers a good deal when compared with AMD’s low-priced Epyc processors. With a smaller hardware and software ecosystem behind them, ARM server chips must offer potential customers a bargain.

[ From Linley Newsletter ] FPGAs Accelerate Deep Learning

[ From Linley Newsletter ] FPGAs Accelerate Deep Learning
Nvidia GPUs are the most popular chips for accelerating deep learning, but some large cloud-service providers (CSPs) are getting better results using FPGAs. For example, Microsoft has deployed FPGAs across its data centers, where they can accelerate its deep-learning algorithms using its Brainwave project. Other CSPs such as Amazon and Baidu also employ this approach for some of their deep neural networks (DNNs). DeePhi, TeraDeep, and other startups offer preprogrammed FPGA accelerators for DNNs. These accelerators mainly target neural-network inferencing, as GPUs dominate the training function.
By Linley Gwennap
The FPGA’s flexibility is well suited to deep learning, a relatively new field that’s developing quickly. Researchers continue to revise DNN algorithms, convolution functions, and data formats. As CSPs gain more experience with their DNN workloads, they discover new optimizations. FPGAs can be reprogrammed in minutes, whereas conventional hardware designs take months or even years to update.
Although some people think of FPGAs as a pile of unstructured gates, these devices also include a set of “hard” features designed directly into the silicon. In addition to basic memory and register blocks, most FPGAs feature hard DSP blocks, because their customers frequently perform signal processing. These DSP blocks are much denser and operate at a higher speed than similar compute blocks constructed from programmable gates. They’re usually configurable for either integer or floating-point calculations.
These DSP blocks offload the multiply-accumulate (MAC) function critical to many DNN algorithms. Some FPGAs have thousands of DSP blocks, generating a huge amount of compute power. Unleashing this performance, however, requires custom gate-level design, a specialized and time-consuming task. Both Intel (formerly Altera) and Xilinx offer tools to ease this burden.

[ From Linley Newsletter ] Microsoft Brainwave Uses FPGAs

[ From Linley Newsletter ] Microsoft Brainwave Uses FPGAs
Microsoft’s Brainwave project demonstrates the advantages of the FPGA approach to deep learning. The company uses deep neural networks (DNNs) in many of its cloud services, including Bing web search, Cortana voice assistant, and Skype Translator. Microsoft wanted a flexible design that could easily adapt as its workloads evolve. Having direct access to production DNNs and large data sets, the company could experiment with alternative hardware designs and data formats to optimize performance. This experimentation led it to develop a new 8-bit floating-point format (FP8) to represent the neural-network weight and activation values.
By Linley Gwennap
To maximize flexibility, Brainwave is a “soft” vector processor that has a custom instruction-set architecture for DNN acceleration. Like Google’s TPU, Brainwave doesn’t run general-purpose code, so the ISA contains a few special-purpose instructions such as matrix multiply, vector operations, convolutions, and nonlinear activations. Each one can operate on hundreds or thousands of data units.
Because it’s instantiated in FPGAs, the instruction set is easily changed. These changes are rolled into a compiler that the team created, maintaining a consistent interface to software. The compiler takes pretrained DNN models developed in multiple frameworks — TensorFlow, Caffe, and Microsoft’s Cognitive Toolkit — and converts them to run on the Brainwave ISA.
The microarchitecture is based on the company’s FP8 format, which halves the size of the compute units and register files compared with standard FP16. The design reads weights from DRAM in FP16 format and converts them to FP8 before storing them in the vector register file. The multiply units then apply the weights to incoming activation data; the results are accumulated and converted back to FP16. Two multifunction units can optionally perform additional multiply-add operations before looping the data back or storing the result in memory. These units can perform activation, normalization, and pooling.
