The Ultimate Computer Acronyms Archive www.acronyms.ch Last updated: May 29, 2000 «I'm sitting in a coffee shop in Milford, NH. In the booth next to me are two men, a father and a son. Over coffee, the father is asking his son about modems, and the son is holding forth pretty well on the subject of fax compatibility, UART requirements, and so on. But he's little out of date: The father asks, "So should I get one with a DSP?" "A what?" says the son. You just can't get far if you're not up on the lingo. You might squeak by in your company of technological nonexperts, but even some of them will surprise you. These days, technical acronyms quickly insinuate themselves into the vernacular.» Raphael Needleman THIS DOCUMENT IS PROVIDED FOR INFORMATIONAL PURPOSES ONLY.

    Supercomputers: Current Status and Future Trends

    Supercomputers: Current Status and Future Trends Presentation to Melbourne PC Users Group, Inc. August 2nd, 2016 http://levlafayette.com 0.0 About Your Speaker 0.1 Lev works as the HPC and Training Officer at the University of Melbourne, and do the day-to-day administration of the Spartan HPC/Cloud hybrid and the Edward HPC. 0.2 Prior to that he worked for several years at the Victorian Partnership for Advanced Computing, which he looked after the Tango and Trifid systems and taught researchers at 17 different universities and research institutions. Prior to that he worked for the East Timorese government, and prior to that the Parliament of Victoria. 0.3 He is involved in various community organisations, collect degrees, learns languages, designs games, and writes books for fun. 0.4 You can stalk him at: http://levlafayette.com or https://www.linkedin.com/in/levlafayette 1.0 What is a Supercomputer anyway? 1.1 A supercomputer is a rather nebulous term for any computer system that is at the frontline of current processing capacity. 1.2 The Top500 metric (http://top500.org) measures pure speed of floating point operations with LINPACK. The HPC Challenge uses a variety of metrics (floating point calculation speed, matrix calculations, sustainable memory bandwidth, paired processor communications, random memory updates, discrete Fourier transforms, and communication bandwidth and latency). 1.3 The term supercomputer is not quite the same as "high performance computer", and not quite the same as "cluster computing", and not quite the same as "scientific (or research) computing". 2.0 What are they used for? 2.1 Typically used for complex calculations where many cores are required to operate in a tightly coupled fashion, or for extremely large collections datasets where many cores are required to carry out the analysis simultaneously.
