Virtual cores and virtual threaded chips could boost chip performance by 4 times and restore performance per watt scaling

http://ift.tt/hZ0OVi

Soft Machines (startup with $125 million in funding and working with Samsung and AMD) developed new VISC™ (Virtual Instruction Set Computing) Architecture (19 page presentation)



Soft Machines demonstrated a 28nm dual-core version of their virtual core approach at the Linley Processor Conference. The 300-400MHz prototype chip ran 32-bit ARM software at performance levels that suggest its technology could provide a leap over current approaches. It looked impressive and could be the gist of a first product.



The startup aimed for 10x improvements but on average expects to deliver still respectable 4x gains. The good news is its technology could be applied to a broad range of chips, from IoT and mobile SoCs to server processors.



The next big target is a quad-core version running at about 1.5 GHz.



• Extracting ILP has significant complexity

• OoO complexity increases quadratically with machine width

• VISC complexity increases linearly with number of virtual cores

• VISC Performance/Watt utilizes linear scaling

Ocean current changes responsible for some ice ages and climate effects

http://ift.tt/hZ0OVi

Rutgers researchers have found that circulation of the ocean plays an equally important role in regulating the earth’s climate as the atmosphere.



In their study, the researchers say the major cooling of Earth and continental ice build-up in the Northern Hemisphere 2.7 million years ago coincided with a shift in the circulation of the ocean – which pulls in heat and carbon dioxide in the Atlantic and moves them through the deep ocean from north to south until it’s released in the Pacific.



The ocean conveyor system, Rutgers scientists believe, changed at the same time as a major expansion in the volume of the glaciers in the northern hemisphere as well as a substantial fall in sea levels. It was the Antarctic ice, they argue, that cut off heat exchange at the ocean's surface and forced it into deep water. They believe this caused global climate change at that time, not carbon dioxide in the atmosphere.

Vanadium Flow Battery Fix the Grid for High Levels of Solar Power

http://ift.tt/hZ0OVi

Imergy Power has a new generation of vanadium flow batteries that dramatically lowers the cost and increases the performance and flexibility of energy storage systems for utilities, renewable energy projects, microgrids, and commercial and industrial customers.



The ESP30 series has a power capability of up to 50 kilowatts (kW) and can store up to 200 kilowatt hours (kWh) of electricity. The power and capacity of the ESP30 make it well suited for a variety of demanding energy storage applications, including peak shaving, demand response, energy shifting, renewable energy firming, and microgrid or back-up power.



It is the first battery from Imergy to use secondary sources of vanadium like mining slag, fly ash, and other environmental waste. As a result of this technology and other developments, Imergy will be able to lower the cost of its flow batteries from $500 per kilowatt hour, already an industry benchmark, to under $300 per kilowatt hour.



The ESP30 operates within a far wider temperature range than lithium ion or other storage solutions and is air-cooled. The storage duration can be extended by increasing electrolyte concentration and volume. Built in a modular fashion from replaceable components, the ESP30 has a lifetime that is effectively unlimited.



Vanadium has is a special material with four different oxidation states. A single element can act as a battery so it does not wear out.



Vanadium utility grade batteries could be placed by the feeder stations to enable shifting of the power generated by solar power on homes by four hours. 4 billion kwh of vanadium batteries could be used to enable the intermittent power of solar energy in the USA which is generated at the wrong time for when consumers need to use it to the right time. These batteries can be completely discharged without damage. Lithium ion and other batteries only last a certain number of charge and discharge cycles and cannot be fully discharged without damage.



There is also over a billion tons of Vanadium in the flyash coal waste that has accumulated over decades. 10 kilograms of vanadium is needed for every kwh of battery. So 40 million tons would be needed for 4 billion kwh. If 100 million houses in the USA had 4 kilowatts of solar power, then that would produce a peak of 400 Gigawatts but the energy generation would be at best be for about 6 hours during the day on sunny days.



Imergy's process does not require highly pure Vanadium. They can handle more contaminated vanadium, which is cheaper and easier to get from the flyash.
