Intel’s Exascale Dataflow Engine Drops X86 And Von Neumann

Intel’s Exascale Dataflow Engine Drops X86 And Von Neumann
With Moore’s Law running out of steam, the chip design wizards at Intel are going off the board to tackle the exascale challenge, and have dreamed up a new architecture that could in one fell swoop kill off the general purpose processor as a concept and the X86 instruction set as the foundation of modern computing. The new architecture that they have dreamed up is called a Configurable Spatial Accelerator, but the word accelerator is a misnomer because what they have come up with is a way to build either processors or coprocessors that are really dataflow engines, not serial processors or vector coprocessors, that can work directly on the graphs that programs create before they are compiled down to CPUs in a traditional sense. The CSA approach is a bit like having a switch ASIC cross-pollenate with a math coprocessor, perhaps with an optional X86 coprocessor perhaps in the mix if it was needed for legacy support…

Make Your Python Prettier With Decorators

Make Your Python Prettier With Decorators
Many Pythonistas are familiar with using decorators, but far fewer understand what’s happening under the hood and can write their own. It takes a little effort to learn their subtleties but, once grasped, they’re a great tool for writing concise, elegant Python. This post will briefly introduce the concept, start with a basic decorator implementation, then walk through a few more involved examples one by one…

Huawei announces Kirin 980: the world’s first 7nm phone chip
Huawei is one of the few phone makers that makes its own chip and it now not only makes chips, it leads the industry with the introduction of the world’s first 7nm mobile chip: welcome the new Kirin 980, a remarkable piece of silicon that combines power and artificial intelligence. The Kirin 980 is the world first in a few areas: the world first made on a super precise 7nm manufacturing process, the world first to implement ARM’s powerful new Cortex A76 CPU, the first with a dual NPU, the first with Mali’s new G76 graphics chip, the first with a super fast 1.4Gbps Category 21 modem and the first to support the faster, 2133MHz LPDDR4X RAM standard…

Google and Harvard made AI to predict earthquake aftershocks

Google and Harvard made AI to predict earthquake aftershocks
Earthquake researchers have been trying to model aftershocks for years. By now, they’re able to fairly accurately predict when aftershocks are going to happen, and how large they’ll be. But they’ve been far from perfect when it comes to pinpointing their location. The answer—of course—appears to be artificial intelligence. A team of collaborators from Google and Harvard team report that after training a neural network, the same kind of AI that powers Facebook photo tagging and Alexa’s voice transcription, on a database of more than 131,000 earthquakes and the locations of their subsequent aftershocks, they’ve come up with the best way yet to predict where future aftershocks will occur. At its core, artificial intelligence is fancy pattern matching: Show it data, whether pictures of someone’s face or the locations of earthquake aftershocks, and the algorithm will try to find the underlying pattern. For facial recognition that pattern is the pixel arrangements that represent a person’s face, and in aftershock prediction its the equation that can be used to explain the reason for aftershock locations…

[ From Linley Newsletter ] Threadripper 2 Grows to 32 Cores

[ From Linley Newsletter ] Threadripper 2 Grows to 32 Cores
Few people really need a 32-core 64-thread PC processor that can hit 4.2GHz, but so what? The folks at AMD will sell you one anyway, just because … they can. And because Intel can’t. So there. It’s reason enough for AMD to introduce the world’s most powerful PC processors — the second-generation Ryzen Threadripper family.
By Tom R. Halfhill
The company positions two of the four family members for content creators who can pay $1,799 to get the 32-core 64-thread 2990WX or $1,299 to get the 24-core 48-thread 2970WX. Video editing, software development, and other compute-intensive tasks are the justification for these monster chips. The other two models are the 16-core 32-thread 2950X and the 12-core 24-thread 2920X, which list for $899 and $649, respectively. They target the high-end desktop PCs prized by avid gamers and by content creators who can’t afford the costlier models. All these chips use the second-generation 12nm Zen+ CPU core that enhances the original 14nm Zen core.
Although these products are much pricier than mainstream PC processors, they’re a bargain for their features and performance. In fact, they resemble server processors. Base clock speeds range as high as 3.5GHz and turbo clocks as high as 4.4GHz. They have up to 16MB of L2 cache, up to 64MB of L3 cache, DDR4-2933 DRAM interfaces with error correction (ECC), and 64 PCI Express (Gen3) lanes.
The 32-core 2990WX and 16-core 2950X shipped on August 13; the others are scheduled for October. In each branch of the family, AMD is delivering the high-end models first, enticing early adopters to spend more money. The low-cost derivatives will arrive two months later, broadening the market. This strategy maximizes revenue and enables the company to ramp production of the chips that will probably sell in larger volumes.
