Researchers find algorithm for large-scale brain simulations
Posted by Saúl Morales Rodriguéz in categories: biotech/medical, information science, neuroscience, supercomputing
An international group of researchers has made a decisive step towards creating the technology to achieve simulations of brain-scale networks on future supercomputers of the exascale class. The breakthrough, published in Frontiers in Neuroinformatics, allows larger parts of the human brain to be represented, using the same amount of computer memory. Simultaneously, the new algorithm significantly speeds up brain simulations on existing supercomputers.
The human brain is an organ of incredible complexity, composed of 100 billion interconnected nerve cells. However, even with the help of the most powerful supercomputers available, it is currently impossible to simulate the exchange of neuronal signals in networks of this size.
“Since 2014, our software can simulate about one percent of the neurons in the human brain with all their connections,” says Markus Diesmann, Director at the Jülich Institute of Neuroscience and Medicine (INM-6). In order to achieve this impressive feat, the software requires the entire main memory of petascale supercomputers, such as the K computer in Kobe and JUQUEEN in Jülich.

Supercomputer on a fingernail, artificial synapse ushers in new AI revolution
Posted by Genevieve Klien in categories: robotics/AI, supercomputing
WHY THIS MATTERS IN BRIEF
There is nothing on Earth like the human brain, even today’s AI doesn’t come close, but now researchers have created an Artificial Synapse that’s 200 million times faster than a human synapse, and one day it will revolutionise AI and computing.

Particle interactions on Titan support the search for new physics discoveries
Posted by Genevieve Klien in categories: nuclear energy, particle physics, supercomputing
Nuclear physicists are using the nation’s most powerful supercomputer, Titan, at the Oak Ridge Leadership Computing Facility to study particle interactions important to energy production in the sun and stars and to propel the search for new physics discoveries.

The New Religions Obsessed with A.I
Posted by Derick Lee in categories: employment, Ray Kurzweil, robotics/AI, singularity, supercomputing
How far should we integrate human physiology with technology? What do we do with self-aware androids—like Blade Runner’s replicants—and self-aware supercomputers? Or the merging of our brains with them? If Ray Kurzweil’s famous singularity—a future in which the exponential growth of technology turns into a runaway train—becomes a reality, does religion have something to offer in response?
Yes, not only is A.I. potentially taking all of our jobs, but it’s also changing religion.

How Chinese scientists used a supercomputer to solve the ancient puzzle called the Three Body Problem
Posted by Mark Larkento in categories: climatology, space, supercomputing
“Scientists and philosophers… had always assumed that the world worked by physical laws, and if you could measure initial conditions accurately enough, those laws would let you predict the future indefinitely. As James Gleick described it in his book Chaos: Making a New Science, this view was very wrong.”
“There was always one small compromise, so small that working scientists usually forgot it was there, lurking in a corner of their philosophies like an unpaid bill. Measurements could never be perfect,” he wrote. “Scientists marching under Newton’s banner actually waved another flag that said something like this: Given an approximate knowledge of a system’s initial conditions and an understanding of natural law, one can calculate the approximate behaviour of the system. This assumption lay at the philosophical heart of science.”
“Today we know how wrong this assumption was. The Three Body Problem is now recognized as a classic example of a chaotic system. Like the butterfly that causes a hurricane by flapping its wings, it is exquisitely sensitive to initial conditions. The tiniest tweak can have massive consequences down the line.”

With the ability to run a quintillion calculations per second—that’s a one with eighteen zeros after it—the implications of an exascale computer would touch nearly every facet of our lives, and would provide the opportunity to potentially solve humanity’s most pressing problems. http://theatln.tc/2xc7QLn

How scientists and supercomputers could make oceans drinkable
Posted by Dan Kummer in categories: nanotechnology, particle physics, supercomputing, sustainability
Aleksandr Noy has big plans for a very small tool. A senior research scientist at Lawrence Livermore National Laboratory, Noy has devoted a significant part of his career to perfecting the liquid alchemy known as desalination—removing salt from seawater. His stock-in-trade is the carbon nanotube. In 2006, Noy had the audacity to embrace a radical theory: Maybe nanotubes—cylinders so tiny, they can be seen only with an electron microscope—could act as desalination filters. It depended on just how wide the tubes were. The opening needed to be big enough to let water molecules flow through but small enough to block the larger salt particles that make seawater undrinkable. Put enough carbon nanotubes together and you potentially have the world’s most efficient machine for making clean water.

Microsoft’s new coding language is made for quantum computers
Posted by Roman Mednitzer in categories: quantum physics, supercomputing
When one of the first personal computers, the Altair 8800 came along in 1976, Microsoft was ready with a programming language, Altair BASIC. It wants to be equally prepared when quantum computers go mainstream, so it has unveiled a new programming language and other tools for the futuristic tech at its Ignite conference. You’ll still need to understand Qubits and other weird concepts, but by integrating traditional languages like C# and Python, Microsoft will make it easier to do mainstream computing on the complex machines.
Quantum computing is famously difficult to grasp — even IBM’s “Beginner’s Guide” is laughingly opaque. In discussing Microsoft’s new initiatives, Bill Gates called the physics “hieroglyphics,” and when asked if he could describe it in one sentence, Satya Nadella said “I don’t think so. I wish I could.”
