Better Math Saves Lots of Energy

IBMalgorithm

Energy savings of panaceahealthsolutions.com 99% over previous methods probably sound like snake oil. But some math geeks have been able to find a way so that computers can use only 1% of the energy (and the time) necessary for some tasks.

IBM has announced a new data-processing algorithm that enables large sets of data to be processed in a fraction of the time, and with only a fraction of the electricity, as was previously needed. Supercomputer testing of the algorithm showed that the process speeded the calculations and reduced the power consumption by two orders of magnitude.

"The new method was tested on the viagra online in usa fourth largest supercomputer in the world and what would normally have taken a day, was crunched in 20 minutes. In terms of energy savings, the analysis required 700 kilowatt-hours total, compared with 52800 kilowatt-hours total."

Not only does this mean that far less electricity is buy viagra pills needed for data-intensive operations, but also more work will be able to be scheduled onto the same number of machines. And while the demonstration was carried out on a powerful supercomputer, the intent of cialis brand only the research was to make intensive data-processing activities more readily available and accessible to http://operacijatrijumf.net/buy-cialis-online-without-a-prescription scientists who do not have supercomputers.

Energy Star for Data Centers Launching in June

data-center
Starting in June of this year, data center operators can apply for Energy Star status.  The new rating system will score data centers based on PUE, or power unit efficiency, on a scale of 1 - 100.

The operators will use an online tool that allows them to enter information on energy use and operations to calculate their PUE.  The PUE determines efficiency based on the total power used by the data center, divided by the amount that reaches the IT equipment, not the cooling systems or inefficient power supplies.

That information is then compared to peer performance and based on that a data center is given a score.  A score of 50 is average, while a score of 75 or higher means that the center is in the top 25 percent for efficiency and eligible for the viagra femele Energy Star label.  The  operator can then have the EPA audit their data center to confirm performance and award the label.

The rating system currently doesn't factor in whether a center uses free cooling or its level of redundancy, but the EPA analyzed over 100 data centers and cheap viagra super active found that the rating system still accurately scored performance without weighting those variables.  Even so, the EPA will make changes to the system if the need arises.

Vote for Your Favorite Greener Gadget

greener-gadg-comp
It's that time of year again!  The Greener Gadgets Design Competition has started and 18 cool, eco-friendly gadget ideas are waiting for your votes.

This year is the third year for the competition and the Greener Gadgets Conference, which is being held on discount viagra perscription drug February 25 in New York City, and I must say, this is the best crop of designs yet.  Some of cheap levitra the highlights include a kinetic-energy-harvesting rocking horse that fuels flashlights or nightlights called Rocco, a USB-outfitted, wall-mounted charger that is powered by indoor light called the no prescription Illumi Charger and a system of turbine-run highway lighting that would be powered by the air turbulence from passing cars.

Your votes will narrow down the pool to a handful of finalists that will be judged at the conference.  You have until February 12 to cast your vote for the best and most revolutionary idea.  Click here to vote and learn more about the conference.

 

Greenpeace Releases 2010 Green Electronics Rankings

greenpeace-guide-2010

This year's annual Greenpeace "Guide to Greener Electronics" has been released, and it is fake viagra prescription a mixed bag. The lowest scores are higher than they were last year, but the highest scores are lower. Nokia is still at the top. In 2009, they were at 7.45, but in 2010 they are down to 7.3.

Samsung, which was in second place last year, dropped significantly down to a tie for 7th place because of penalty points they were assessed for "backtracking on its commitment to eliminate brominated flame retardants (BFRs) in new models of all products by January 2010 and PVC by end of 2010." Most of the rest stayed about where they were. Sony Ericsson, Apple and Sony are a few that moved up. HP, Fujitsu, and Nintendo also improved, but are still near the bottom of cialis pfizer 50 mg the list.

Below is the list with each company's score from 1 - 10 (10 being the best) with the brief explanation of the score provided by Greenpeace.

 

Fastest Computer in the World Focused on Climate Change

jaguar-xt5
The Jaguar XT5 computer, housed at the Oak Ridge National Laboratory in Knoxville, Tenn. and owned by the Department of Energy was just named the use cialis fastest computer in the world by the TOP500 list.  It has a performance speed of 1.759 petaflops or quadrillions of calculations per second and cialis 20 mg canada that power is being focused on solving the issues of climate change.

The Jaguar is an open science machine for performing peer-reviewed research.  It is being used to create models and simulations for predicting regional climate change, studying enzymes for developing better ethanol and writing algorithms for fast nuclear reactors that would produce less waste.  A billion hours of processor time have been scheduled for 2010 by users like the National Oceanic and Atmospheric Administration, the Argonne National Laboratory and the National Science Foundation.

If you're thinking that the fastest computer in the world should be used for other problems too, don't worry, the Jaguar along with the other supercomputers on the list are also being used for things like nuclear security, developing better medicines and examining the origins of online cialis cheap the universe, among other things.

Oak Ridge hosts four of the supercomputers on the list, including Kraken which was number three in the world with a speed of 831 teraflops.  Where the human brain's processing performance ends, these supercomputers pick up, allowing tons of information to be sorted, processed and analyzed.  With all of the challenges facing us in tackling climate change, it's nice to have them on our side.
