NVIDIA Unveils Next Gen Pascal GPU With Stacked 3D DRAM and GeForce GTX Titan Z 110

MojoKid (1002251) writes "NVIDIA's 2014 GTC (GPU Technology Conference) kicked off today in San Jose California, with NVIDIA CEO Jen-Hsun Huang offering up a healthy dose of new information on next generation NVIDIA GPU technologies. Two new NVIDIA innovations will be employed in their next-gen GPU technology, now know by its code named 'Pascal." First, there's a new serial interconnect known as NVLink for GPU-to-CPU and GPU-to-GPU communication. Though details were sparse, apparently NVLink is a serial interconnect that employs differential signaling with embedded clock and it allows for unified memory architectures and eventually cache coherency. It's similar to PCI Express in terms of command set and programming model but NVLink will offer a massive 5 — 12X boost in bandwidth up to 80GB/sec.

The second technology to power NVIDIA's forthcoming Pascal GPU is 3D stacked DRAM technology.The technique employs through-silicon vias that allow the ability to stack DRAM die on top of each other and thus provide much more density in the same PCB footprint for the DRAM package. Jen-Hsun also used his opening keynote to show off NVIDIA's most powerful graphics card to date, the absolutely monstrous GeForce GTX Titan Z. The upcoming GeForce GTX Titan Z is powered by a pair of GK110 GPUs, the same chips that power the GeForce GTX Titan Black and GTX 780 Ti. All told, the card features 5,760 CUDA cores (2,880 per GPU) and 12GB of frame buffer memory—6GB per GPU. NVIDIA also said that the Titan Z's GPUs are tuned to run at the same clock speed, and feature dynamic power balancing so neither GPU creates a performance bottleneck."

Submission + - Facebook to buy Oculus Rift for $2 billion (muktware.com)

sfcrazy writes: Facebook is on spending and acquiring spree, after shelling out over $19 billion on WhatsApp the company is now buying the latest sensation Oculus VR for $2 billion. This is the first of its kind hardware purchase for Facebook and it’s not clear what a social networking site is going to do with a VR company, well if arch-rival Google can buy robots why can’t Facebook buy virtual reality specialists?

Florida Judge Rules IP Address Can't Identify a BitTorrent Pirate 158

An anonymous reader writes "Florida District Court Judge Ursula Ungaro has dismissed a lawsuit brought by Malibu Media against an alleged BitTorrent pirate. Though Malibu Media explained how they geolocated the download site and verified that the IP address was residential rather than a public wifi hotspot, the judge reasoned that the 'Plaintiff has not shown how this geolocation software can establish the identity of the Defendant....Even if this IP address is located within a residence, the geolocation software cannot identify who has access to that residence's computer and who would actually be using it to infringe Plaintiff's copyright.' Judge Ungaro's ruling is not the first of its kind, but it could signal a growing legal trend whereby copyright lawsuits can no longer just hinge on the acquisition of an IP address."

How Do You Backup 20TB of Data? 983

Sean0michael writes "Recently I had a friend lose their entire electronic collection of music and movies by erasing a RAID array on their home server. He had 20TB of data on his rack at home that had survived a dozen hard drive failures over the years. But he didn't have a good way to backup that much data, so he never took one. Now he wishes he had.

Asking around among our tech-savvy friends though, no one has a good answer to the question, 'how would you backup 20TB of data?'. It's not like you could just plug in an external drive, and using any cloud service would be terribly expensive. Blu-Ray discs can hold a lot of data, but that's a lot of time (and money) spent burning discs that you likely will never need. Tape drives are another possibility, but are they right for this kind of problem? I don' t know. There might be something else out there, but I still have no feasible solution.

So I ask fellow slashdotters: for a home user, how do you backup 20TB of Data?"
Even Amazon Glacier is pretty pricey for that much data.

Scientists Build Three Atom Thick LEDs 54

minty3 tipped us to news that UW researchers have built the thinnest LEDs yet: a mere three atoms thick. Quoting El Reg: "Team leader Xiaodong Xu, a UW assistant professor in physics and materials science and engineering, and his graduate student Ross, have published the technique in the latest issue of Nature Nanotechnology. They report that the LEDs are small and powerful enough to be used in optical chips that use light instead of electricity to shuttle signals and data through a processor, or they could be stacked to make new thin and flexible displays."

well the assume anyways - other giant viruses are the same in that they only attack amoebae but this giant virus is also unlike anything they ever tested. The basically set the permafrost in a container and let it go to work. They didn't try other organisms. so their assumptions are partially based on the work of prior giant viruses.

Scientists Revive a Giant 30,000 Year Old Virus From Ice 121

bmahersciwriter writes "It might be terrifying if we were amoebae. Instead, it's just fascinating. The virus, found in a hunk of Siberian ice, is huge, but also loosely packaged, which is strange says evolutionary biologist Jean-Michel Claverie: 'We thought it was a property of viruses that they pack DNA extremely tightly into the smallest particle possible, but this guy is 150 times less compacted than any bacteriophage [viruses that infect bacteria]. We don't understand anything anymore!'"

How To Take Apart Fukushima's 3 Melted-Down Reactors 167

the_newsbeagle writes "In Japan, workers have spent nearly three years on the clean-up and decommissioning of the ruined Fukushima Daiichi nuclear power station. They only have 37 years to go. Taking apart the plant's three melted-down reactors is expected to take 40 years and cost $15 billion. The plant's owner, TEPCO, admits that its engineers don't yet know how they'll pull off this monumental task. An in-depth examination of the decommissioning process explains the challenges, such as working amid the radioactive rubble, stopping up the leaks that spill radioactive water throughout the site, and handling the blobs of melted nuclear fuel. Many of the tasks will be accomplished by newly invented robots that can go where humans fear to tread."

Japan To Create a Nuclear Meltdown 222

Taco Cowboy writes "Japanese researchers are planning an experiment to better understand what transpires during a nuclear meltdown by attempting to create a controlled nuclear meltdown. Using a scaled down version of a nuclear reactor — essentially a meter long stainless steel container — the experiment will involve the insertion of a foot long (30 cm) nuclear fuel rod, starting the fission process, and then draining the coolant. The experiment is scheduled to take place later this year."

Enormous Tunneling Machine 'Bertha' Blocked By 'The Object' 339

An anonymous reader sends word that 'Bertha,' the world's largest tunneling machine, which is currently boring a passage beneath Seattle's waterfront, has been forced stop. The 57.5ft diameter machine has encountered an unknown obstruction known as "the object." "The object’s composition and provenance remain unknown almost two weeks after first contact because in a state-of-the-art tunneling machine, as it turns out, you can’t exactly poke your head out the window and look. 'What we’re focusing on now is creating conditions that will allow us to enter the chamber behind the cutter head and see what the situation is,' [said project manager Chris Dixon]. Mr. Dixon said he felt pretty confident that the blockage will turn out to be nothing more or less romantic than a giant boulder, perhaps left over from the Ice Age glaciers that scoured and crushed this corner of the continent 17,000 years ago. But the unknown is a tantalizing subject. Some residents said they believe, or want to believe, that a piece of old Seattle, buried in the pell-mell rush of city-building in the 1800s, when a mucky waterfront wetland was filled in to make room for commerce, could be Bertha’s big trouble. That theory is bolstered by the fact that the blocked tunnel section is also in the shallowest portion of the route, with the top of the machine only around 45 feet below street grade."
