Compilers and More: Is Amdahl’s Law Still Relevant?

Jan 22, 2015 |

From time to time, you will read an article or hear a presentation that states that some new architectural feature or some new programming strategy will let you work around the limits imposed by Amdahl’s Law. I think it’s time to finally shut down the discussion of Amdahl’s Law. Here I argue that the premise Read more…

NextScale Nodes Crest 1 Teraflops, Await Knights Landing

Nov 19, 2014 |

When the dust settles after its acquisition of the System x business from IBM, Lenovo Group will probably end up with the second largest HPC systems business in the world, behind Hewlett-Packard and eager to close that gap just as it has in the PC market. Lenovo came out swinging at the SC14 supercomputing conference Read more…

Jülich Tag Teams With IBM, Nvidia On Data Centric Computing

Nov 10, 2014 |

The Power Acceleration and Design Center that has just been launched at the Jülich Supercomputing Center in Munich, Germany, is not just about focusing the system research and software development around IBM’s Power processors and Nvidia’s Tesla GPU accelerators. More importantly, the center is hanging out a shingle and letting organizations in Europe know where Read more…

Peering Backward to the Big Bang with the CTC and COSMOS

Oct 10, 2014 |

At the Stephen Hawking Centre for Theoretical Cosmology (CTC) in Cambridge University, we are endeavouring to push back our understanding to the very beginnings of the Universe, tiny fractions of a second after the Big Bang. Cosmology has had many successes but it leaves many questions unanswered concerning how the Universe came into being and Read more…

Will Magnets Be the Cure for What Ails Moore’s Law?

Oct 1, 2014 |

With silicon-based processors facing some inexorable limits, scientists are looking elsewhere to keep computing on its exponential growth track. One potential alternative that is getting some traction is magnet-based computing. A group of electrical engineers at the Technische Universität München (TUM) is studying the feasibility of using miniature magnets as the building block for integrated Read more…

IBM Advances Self-Assembly in 3D Transistors

Jan 28, 2015 |

The key to Moore’s law is the ability to incorporate ever-smaller feature sizes into each new chip generation. While the exponential progress ensconced in the “law” has slowed down in the last decade, the payoff is still compelling enough that chip engineers will go to great lengths to forestall its long-predicted demise. One of these Read more…

NVIDIA K80 GPU-System Speeds Up Bioinformatics Tool 12X

Jan 28, 2015 |

Not long ago, the high cost and relative slowness of DNA sequencing were the rate-limiting bottlenecks in biomedical research. Today, post-sequencing data analysis is the biggest challenge. The reason, of course, is the prodigious output from modern next-generation sequencing (NGS) instruments (e.g., Illumina and ThermoFisher/Life Technologies) overwhelming analysis pipelines. Efficiently sifting the data treasure trove Read more…

Baidu Supercomputer Tops Google in Image Recogition

Jan 20, 2015 |

In an effort to oust Google from its the top spot in image recognition, Baidu, Inc. has dedicated a supercomputer to what it claims to be the world’s most accurate computer vision system. Using the ImageNet object classification benchmark, the Chinese search engine company claims that their system managed a 5.98 percent error rate, which Read more…

NVIDIA GPUs Unfold Secrets of the Human Genome

Jan 16, 2015 |

With 3 billion base pairs of DNA on hand, it’s no wonder that genes are able to program nearly ever detail of our physical makeup, from constructing organs to fighting off disease. But how can a system so vast find the right operating manual for one body part, and ignore all the data meant for Read more…

Unmasking the Speed Limit of Modern Electronics

Dec 11, 2014 |

For the first time, scientists have captured the essence of semiconductor computing on film by taking snapshots of the electron transfer from valence to conduction band states. It is this leap that forms the basis for the entire semiconductor industry, digital electronics and modern computing as we know it. Using attosecond extreme ultraviolet (XUV) spectroscopy Read more…
