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.

Can Artificial Intelligence Be Ethical?

Posted by in categories: information science, robotics/AI

Good question? Answer as of to date — depends on the “AI creator.” AI today is all dependent upon architects, engineers, etc. design and development and the algorithms & information exposed in AI. Granted we have advanced this technology; however, it is still based on logical design and principles; nothing more.

BTW — here is an example to consider in this argument. If a bank buys a fully functional and autonomous AI; and through audits (such as SOX) it is uncovered that embezzling was done by this AI solution (like in another report 2 weeks ago showing where an AI solution stole money out of customer accounts) who is at fault? Who gets prosecuted? who gets sued? The bank, or the AI technology company; or both? We must be ready to address these types of situations soon and legislation and the courts are going to face some very interesting times in the near future; and consumers will probably take the brunt of the chaos.


A recent experiment in which an artificially intelligent chatbot became virulently racist highlights the challenges we could face if machines ever become superintelligent. As difficult as developing artificial intelligence might be, teaching our creations to be ethical is likely to be even more daunting.

How Self-Replicating Spacecraft Could Take Over the Galaxy

Posted by in categories: alien life, robotics/AI, space travel

Forget about generation ships, suspended animation, or the sudden appearance of a worm hole. The most likely way for aliens to visit us — whatever their motive — is by sending robotic probes. Here’s how swarms of self-replicating spacecraft could someday rule the galaxy.

Back in late 1940’s the Hungarian mathematician John Von Neumann wondered if it might be possible to design a non-biological system that could replicate itself in a cellular automata environment, what he called a universal constructor. Von Neumann wasn’t thinking about space exploration at the time, but other thinkers like Freeman Dyson, Eric Drexler, Ralph Merkle, and Robert Freitas later took his idea and applied it to exactly that.

Bigelow Aerospace and United Launch Alliance Join Forces to Foster a New Era of Sustainable Commercialization in Low Earth Orbit

Posted by in categories: space, sustainability

Colorado Springs, Colo., (April 11, 2016) – Bigelow Aerospace (BA) and United Launch Alliance (ULA) announced they are partnering to develop and deploy habitable volumes in Low Earth orbit (LEO). The volumes will be based on the Bigelow Aerospace B330 expandable module with the initial launch to orbit in 2020 on ULA’s Atlas V 552 configuration launch vehicle.

The B330 will have 330 cubic meters (12,000 cu ft) of internal space. The craft will support zero-gravity research including scientific missions and manufacturing processes. Beyond its industrial and scientific purposes, however, it has potential as a destination for space tourism and a craft for missions destined for the Moon and Mars.

“We are exploring options for the location of the initial B330 including discussions with NASA on the possibility of attaching it to the International Space Station (ISS),” said Robert Bigelow, founder and president of Bigelow Aerospace. “In that configuration, the B330 will enlarge the station’s volume by 30% and function as a multipurpose testbed in support of NASA’s exploration goals as well as provide significant commercial opportunities. The working name for this module is XBASE or Expandable Bigelow Advanced Station Enhancement.”

Microbots can clean up polluted water

Posted by in category: bioengineering

(Phys.org)—A new study shows that a swarm of hundreds of thousands of tiny microbots, each smaller than the width of a human hair, can be deployed into industrial wastewater to absorb and remove toxic heavy metals. The researchers found that the microbots can remove 95% of the lead in polluted water in one hour, and can be reused multiple times, potentially offering a more effective and economical way to remove heavy metals than previous methods.

The researchers, Diana Vilela, et al., have published a paper on the lead-adsorbing microbots in a recent issue of Nano Letters.

“This work is a step toward the development of smart remediation system where we can target and remove traces of pollutant without producing an additional contamination,” coauthor Samuel Sánchez, at the Max-Planck Institute for Intelligent Systems in Stuttgart, Germany; the Institute for Bioengineering of Catalonia in Barcelona; and the Catalan Institution for Research and Advanced Studies in Barcelona, told Phys.org.

NASA Begins Testing of Revolutionary E-Sail Technology

Posted by in category: space travel

Testing has started at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on a concept for a potentially revolutionary propulsion system that could send spacecraft to the edge of our solar system, the heliopause, faster than ever before.

The test results will provide modeling data for the Heliopause Electrostatic Rapid Transit System (HERTS). The proposed HERTS E-Sail concept, a propellant-less propulsion system, would harness solar wind to travel into interstellar space.

“The sun releases protons and electrons into the solar wind at very high speeds — 400 to 750 kilometers per second,” said Bruce Wiegmann an engineer in Marshall’s Advanced Concepts Office and the principal investigator for the HERTS E-Sail. “The E-Sail would use these protons to propel the spacecraft.”

NASA Expands Economic Research to Advance Space Development

Posted by in categories: economics, space

The global space economy is growing, generating more than $300 billion a year in space-related activities, and attracting new, diverse participants and investors. A recent study also found more private money invested in commercial space development in 2015 than in the previous 15 years combined.

NASA has selected six new research proposals to understand the effective drivers of investments in the space economy.

In its second call for economic studies related to investments in the space economy, the agency picked studies that cover topics ranging from in-space manufacturing in low-Earth orbit (LEO) to the economics of resources obtained from near-Earth objects (NEO), such as asteroids.
