The theme this year is one of continuity—as evolution rather than stasis. Predictions has been published since 2001. Back in 2009 and 2010, we wrote about the launch of exciting new fourth-generation wireless networks called 4G (aka LTE). A decade later, we’re now making predic- tions about 5G networks that will be launching this year. -
PC Gamers Win Big
CASE STUDY Intel® Solid-State Drives Performance, Storage and the Customer Experience PC Gamers Win Big Intel® Solid-State Drives (SSDs) deliver the ultimate gaming experience, providing dramatic visual and runtime improvements Intel® Solid-State Drives (SSDs) represent a revolutionary breakthrough, delivering a giant leap in storage performance. Designed to satisfy the most demanding gamers, media creators, and technology enthusiasts, Intel® SSDs bring a high level of performance and reliability to notebook and desktop PC storage. Faster load times and improved graphics performance such as increased detail in textures, higher resolution geometry, smoother animation, and more characters on the screen make for a better gaming experience. Developers are now taking advantage of these features in their new game designs. SCREAMING LOAD TiMES AND SMOOTH GRAPHICS With no moving parts, high reliability, and a longer life span than traditional hard drives, Intel Solid-State Drives (SSDs) dramatically improve the computer gaming experience. Load times are substantially faster. When compared with Western Digital VelociRaptor* 10K hard disk drives (HDDs), gamers experienced up to 78 percent load time improvements using Intel SSDs. Graphics are smooth and uninterrupted, even at the highest graphics settings. To see the performance difference in a head-to- head video comparing the Intel® X25-M SATA SSD with a 10,000 RPM HDD, go to www.intelssdgaming.com. When comparing frame-to-frame coherency with the Western Digital VelociRaptor 10K HDD, the Intel X25-M responds with zero hitching while the WD VelociRaptor shows hitching seven percent of the time. This means gamers experience smoother visual transitions with Intel SSDs. -

These are the first measurements for two of the systems. We also present the earliest measurements of relative position for 17 others. We include orbits for six of the systems, two revised and four reported for the first time. For one of 0.1175 0.0079 the systems with a new orbit, G 161-7, we determine masses of 0.156 ± 0.011 and for the A and B components, respectively. All six of these new calculated orbits have short periods (between fiveand38years) and hold the promise of deriving accurate masses in the near future. -

Survey and Benchmarking of Machine Learning Accelerators
1 Survey and Benchmarking of Machine Learning Accelerators Albert Reuther, Peter Michaleas, Michael Jones, Vijay Gadepally, Siddharth Samsi, and Jeremy Kepner MIT Lincoln Laboratory Supercomputing Center Lexington, MA, USA freuther,pmichaleas,michael.jones,vijayg,sid,[email protected] Abstract—Advances in multicore processors and accelerators components play a major role in the success or failure of an have opened the flood gates to greater exploration and application AI system. of machine learning techniques to a variety of applications. These advances, along with breakdowns of several trends including Moore’s Law, have prompted an explosion of processors and accelerators that promise even greater computational and ma- chine learning capabilities. These processors and accelerators are coming in many forms, from CPUs and GPUs to ASICs, FPGAs, and dataflow accelerators. This paper surveys the current state of these processors and accelerators that have been publicly announced with performance and power consumption numbers. The performance and power values are plotted on a scatter graph and a number of dimensions and observations from the trends on this plot are discussed and analyzed. For instance, there are interesting trends in the plot regarding power consumption, numerical precision, and inference versus training. We then select and benchmark two commercially- available low size, weight, and power (SWaP) accelerators as these processors are the most interesting for embedded and Fig. 1. Canonical AI architecture consists of sensors, data conditioning, mobile machine learning inference applications that are most algorithms, modern computing, robust AI, human-machine teaming, and users (missions). Each step is critical in developing end-to-end AI applications and applicable to the DoD and other SWaP constrained users. -

NEARBY M DWARF STARS AND THE WIDE MAIN SEQUENCE by Tiffany Danielle Clements Under the Direction of Todd Henry, PhD ABSTRACT This dissertation addresses the underlying causes for the observed widening of the main sequence for low mass stars and presents the results of three different studies using two different astrophysical observing methods to assess the properties of a sample of nearby, M dwarf stars and how these properties affect a star's position on an H-R diagram. The first study is the assessment of the activity of the internal magnetic fields of 76 southern nearby, M dwarf stars through measurements of the relative changes in their V magnitudes over time periods of years. This long-term variability is then analyzed with respect to the vertical positions of these stars on the main sequence to determine the effects of stellar activity on these positions. -

ACRONYM IX Round 5 Tossups
ACRONYM IX Round 5 Tossups 1. After failing to fit in at his father and brothers' workplace, this character is hired for a project that parodies a real life one by John Galliano. This character is the namesake of a New York learning institution whose roof resembles a book. This man's use of Ferrari and Le Tigre are criticized by a man who invented the piano key necktie. After some of his friends are killed in a gasoline fight, this nonambiturner struggles to give a "eugoogly." For 10 points, name this former rival of Hansel, a Ben Stillerportrayed male model. ANSWER: Derek Zoolander 2. The most commonly used version of this phrase was recorded by Young Busco. One viral use of this phrase was set to the tune of the Jurassic Park theme and photoshopped certain items onto multiple dinosaurs. When Michael Jordan was asked this question at a school assembly, he responded that he was "lost on that Vine stuff" and gave an answer of "29 lows." A viral video depicted an unsuspecting police officer being asked, for 10 points, what obnoxious question regarding his choice of footwear? ANSWER: What are those? 3. One group in this TV series speaks the English language variant Trigedasleng. One character in this series, who was kept secret due to a onechild policy, is devastated when an acid fog kills her love interest Atom. While exploring what used to be Virginia, this show's title characters encounter several tribes near Mount Weather known as Grounders. For 10 points, name this CW series in which a conglomerated space station sends a group of 'delinquents' exploring Earth, which is made up of the title number of people.
