Supercomputers Aid in Quantum Materials Research

Posted by in categories: mathematics, quantum physics, supercomputing, transportation

Lov’n Quantum Espresso


Researchers use specialized software such as Quantum ESPRESSO and a variety of HPC software in conducting quantum materials research. Quantum ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling, based on density-functional theory, plane waves and pseudo potentials. Quantum ESPRESSO is coordinated by the Quantum ESPRESSO Foundation and has a growing world-wide user community in academic and industrial research. Its intensive use of dense mathematical routines makes it an ideal candidate for many-core architectures, such as the Intel Xeon Phi coprocessor.

The Intel Parallel Computing Centers at Cineca and Lawrence Berkeley National Lab (LBNL) along with the National Energy Research Scientific Computing Center (NERSC) are at the forefront in using HPC software and modifying Quantum ESPRESSO (QE) code to take advantage of Intel Xeon processors and Intel Xeon Phi coprocessors used in quantum materials research. In addition to Quantum ESPRESSO, the teams use tools such as Intel compilers, libraries, Intel VTune and OpenMP in their work. The goal is to incorporate the changes they make to Quantum ESPRESSO into the public version of the code so that scientists can gain from the modification they have made to improve code optimization and parallelization without requiring researchers to manually modify legacy code.

Can optical technology solve the high performance computing energy conundrum?

Posted by in categories: energy, quantum physics, supercomputing

Another pre-Quantum Computing interim solution for super computing. So, we have this as well as Nvidia’s GPU. Wonder who else?


In summer 2015, US president Barack Obama signed an order intended to provide the country with an exascale supercomputer by 2025. The machine would be 30 times more powerful than today’s leading system: China’s Tianhe-2. Based on extrapolations of existing electronic technology, such a machine would draw close to 0.5GW – the entire output of a typical nuclear plant. It brings into question the sustainability of continuing down the same path for gains in computing.

One way to reduce the energy cost would be to move to optical interconnect. In his keynote at OFC in March 2016, Professor Yasuhiko Arakawa of University of Tokyo said high performance computing (HPC) will need optical chip to chip communication to provide the data bandwidth for future supercomputers. But digital processing itself presents a problem as designers try to deal with issues such as dark silicon – the need to disable large portions of a multibillion transistor processor at any one time to prevent it from overheating. Photonics may have an answer there as well.

The Ultimate Debate – Interconnect Offloading Versus Onloading

Posted by in categories: computing, quantum physics

When I read articles like this one; I wonder if folks really fully understand the full impact of what Quantum brings to all things in our current daily lives.


The high performance computing market is going through a technology transition – the Co-Design transition. As has already been discussed in many articles, this transition has emerged in order to solve the performance bottlenecks of today’s infrastructures and applications, performance bottlenecks that were created by multi-core CPUs and the existing CPU-centric system architecture.

How are multi-core CPUs the source for today’s performance bottlenecks? In order to understand that, we need to go back in time to the era of single-core CPUs. Back then, performance gains came from increases in CPU frequency and from the reduction of networking functions (network adapter and switches). Each new generation of product brought faster CPUs and lower-latency network adapters and switches, and that combination was the main performance factor. But this could not continue forever. The CPU frequency could not be increased any more due to power limitations, and instead of increasing the speed of the application process, we began using more CPU cores in parallel, thereby executing more processes at the same time. This enabled us to continue improving application performance, not by running faster, but by running more at the same time.

D-Wave Systems is most disruptive company we’ve ever seen, says Paradigm

Posted by in categories: computing, finance, quantum physics, robotics/AI

D-Wave not only created the standard for Quantum Computing; they are the standard for QC in N. America at least. Granted more competitors will enter the field; however, D-Wave is the commercial competitor with proven technology and credentials that others will have to meet up to or excel past to be a real player in the QC landscape.


Burnaby-based D-Wave, which was founded in 1999 as a spin-off from the physics department of the University of British Columbia has become nothing less than the leading repository of quantum computing intellectual property in the world, says the analyst. He thinks D-Wave’s customers will be positioned to gain massive competitive advantages because they will be able to solve problems that normal computers simply can’t, such those in areas such as DNA sequencing, financial analysis, and artificial intelligence.

“We stand at the precipice of a computing revolution,” says Kim. “Processing power is taking a huge leap forward thanks to ingenious innovations that leverage the counter-intuitive and unique properties of the quantum realm. Quantum mechanics, theorized many decades ago, is finally ready for prime time. Imagine, if we could go back to 1946 and have the same foresight with the ENIAC, the first electronic general-purpose computer. ENIAC’s pioneers created a new industry and opened up unimaginable possibilities. The same opportunity exists today with D-Wave Systems. D-Wave is the world’s first quantum computing company and represents the most unique and disruptive company that we have seen in our career.

The Big Bang: Arriving at the site of creation

Posted by in categories: mathematics, quantum physics, singularity, space

Part 2


In part 1 of the journey, we saw the leading observations that needed explanation. Explanations that we want to do through the theory of relativity and quantum mechanics. No technical and expert knowledge in these theories yet, only scratches of its implications. So let us continue.

THE RELATIVITY THEORY Deducing from the Hubble expansion, the galaxies were close in the distant past but certainly not in this current form as the telescopes now see them receding. In fact, if they were receding it also means they were expanding.

Therefore, when we reverse the receding galaxies into the far distant past they should end up at a point somewhere sometime with the smallest imaginable extension, if that extension is conceivable at all. Scientists call it the singularity, a mathematical deduction from the relativity theory. How did this immeasurable Universe made of clusters of galaxies we now see ever existed in that point called singularity?

Second digital revolution

Posted by in categories: habitats, internet, neuroscience, quantum physics, robotics/AI, security

Many folks talk about the whole AI revolution; and indeed it does change some things and opens the door the for opportunities. However, has it truly changed the under lying technology? No; AI is still reliant on existing digital technology. The real tech revolution will come in the form of Quantum tech over the next 7 to 8 years; and it will change everything in our lives and industry. Quantum will change everything that we know about technology including devices, medical technologies, communications including the net, security, e-currency, etc. https://lnkd.in/bJnS37r


If you were born in the 1970s or 1980s, you probably remember the Jetsons family. The Jetsons are to the future what the Flintstones are to the past. That futuristic lifestyle vision goes back several decades; self-driving vehicles, robotic home helpers and so on. What looked like a cartoon series built on prolific imagination seems somewhat more real today. Newly developed technologies are becoming available and connecting everything to the internet. This is the-internet-of-things era.

These ‘things’ are not new. They are just standard devices – lights, garage doors, kitchen appliances, household appliances – equipped with a little intelligence. Intelligence that is possible thanks to three emerging technologies: sensors to collect information from surroundings; the ability to control something; and communication capability allowing devices to talk to each other.

ORNL, UT Team Up on Breakthrough That Could Aid Quantum Computing

Posted by in categories: computing, engineering, particle physics, quantum physics

Another reason for being in east TN this month.


Genevieve Martin/ORNL This rendering illustrates the excitation of a spin liquid on a honeycomb lattice using neutrons. As with many other liquids, it is difficult to see a spin liquid unless it is “splashed,” in this case by neutrons depicted as moving balls. The misaligned and vibrating spin pair in the middle signifies the ephemeral Majorana fermion constantly in motion. The ripples formed when the neutrons hit the spin liquid represent the excitations that are a signature of the Majorana fermions. The atomic structure on the left signifies the honeycomb alpha-ruthenium trichloride, in which each ruthenium atom has a spin and is surrounded by a cage of chlorine atoms.

Researchers from the U.S. Department of Energy’s Oak Ridge National Laboratory and UT’s Department of Materials Science and Engineering and Department of Physics and Astronomy used neutrons to uncover novel behavior in materials that holds promise for quantum computing.
