What Makes a Supercomputer? In a fascinating exploration of modern computing, the YouTube video "What Makes a Supercomputer?" takes viewers inside the world of supercomputing at the Texas Advanced Computing Center (TACC) at the University of Texas, Austin. The video, hosted by Norm from Test.com, features insights from experts in the field, Dan Stanzione and Kelly Gaither, discussing the intricacies of supercomputer technology and its applications in scientific research.

Overview of Supercomputers​

The video begins with a discussion on what defines a supercomputer and how these machines are ranked in terms of power and capability. Dan Stanzione explains that the TACC’s current machine, Stampede, is one of the fastest computers globally, with a peak performance of 9 to 10 petaflops (petaflops refers to one quadrillion floating-point operations per second). To put this in perspective, Stanzione illustrates that this performance is about a million times faster than a high-end consumer desktop PC.

Design and Components​

Modern supercomputers differ significantly from traditional models like the Kray machines. They are primarily built from clusters of networked computers rather than custom-built silicon. This shift allows for an enormous amount of parallel processing: Stampede, for example, utilizes 64 hundred servers powered by Intel Xeon processors along with Xeon Phi co-processors designed for high-performance computing tasks. This design choice enables the TACC to combine both performance and cost-effectiveness, allowing many slower chips to work together for increased overall capability.

Applications in Research​

The applications of such supercomputers are vast, encompassing fields such as climate modeling, genomics, astrophysics, and materials science. With over 1,500 projects running concurrently, researchers utilize Stampede for simulations ranging from earthquake modeling to analyzing colliding black holes.

Visualization Technology​

Kelly Gaither, the director of visualization at TACC, discusses the challenges of interpreting the massive amounts of data generated by supercomputers. In her role, she focuses on creating more intuitive visualization techniques, drawing inspiration from modern media and technology to help scientists better understand their data. For instance, leveraging large multi-display setups, similar to those seen in films like Minority Report, helps researchers visualize and compare complex data sets effectively.

Future of Supercomputing​

Moore's Law traditionally describes how computing power doubles approximately every two years. However, Stanzione suggests that supercomputing is advancing even faster than this trend. The next generation of supercomputers aims for exaflop performance (one billion billion operations per second), with expectations set for near-future developments. The evolution of computational technology, driven by both hardware improvements and architectural advancements, positions supercomputers to continue leading scientific inquiry.

Conclusion​

The video provides a comprehensive look at the minds behind supercomputing technology and the machines that shape scientific exploration today. For anyone intrigued by computing, science, or technology, this glimpse into the future of supercomputing at TACC is a must-watch.​
