Supercomputing Increments Towards the Exaflop Era

The November 2012 biannual list of the world’s fastest supercomputers shows the winner incrementally improving over the last measure. The Titan (a Cray XK7, Opteron 6274 16C 2.200GHz, Cray Gemini interconnect, NVIDIA K20x) is leading with 17.6 petaflops per second of maximum processing power. This was only an 8% increase in maximum processing speed as compared to other recent increases of 30-60%, but a continued step forward in computing power.

Supercomputers are used for a variety of complicated modeling problems where simultaneous processing is helpful such as weather modeling, quantum physics, and predicting degradation in nuclear weapons arsenals.

Increasingly, supercomputing is being seen as just one category of big data computing along with cloud-based server farms running simple algorithms over large data corpuses (for example Google’s cat image recognition project), crowd-based distributed computing networks (e.g.; protein Folding@home with 5 petaflops of computing power, and crowdsourced labor networks (e.g.; Mechanical Turk, oDesk, CrowdFlower - theoretically comprising 7 billion Turing test-passing online agents).
 

The big data graph era

With the start of the big data era and the ability to collect, store and render meaningful numerous data points, the cultural outlook of the world is shifting too. Graphs, graphs, graphs. Individuals and communities have a social graph, taste graph, preference graph, affinity graph, attention graph, intention graph, values graph, emotion graph, health graph and more.

Graphing theory is being applied to many new contexts such as social networks, media consumption, nanotechnology fabrication, gaming, and genomic analysis and could be one of the many data analysis techniques applied to any large dataset. VLDS – very large datasets – and moving back into the cloud mean that sophisticated data analysis and artificial intelligence techniques could be an expected feature of websites just like social networking commentary and gaming elements have become today.
