TACC's Longhorn Visualization Cluster Enables Scientific Insight with Dell Hardware

Interview with Kelly Gaither, Director of Data & Information Analysis, Texas Advanced Computing Center (TACC). Longhorn is the largest hardware-accelerated, interactive visualization cluster in the world, capable of providing data visualization at an unprecedented scale. Located at the Texas Advanced Computing Center (TACC) at The University of Texas at Austin, the system provides scientists with unprecedented visualization capabilities and enables them to effectively analyze ever-growing volumes of data. To date, there are 486 active projects on the system and more than 40,425 jobs have been completed.

Memory Bandwidth and Performance, Part 2

In our last installment, we introduced the concept that performance was not all about clock rate and core count, and how in particular access speed to main memory often dominated performance. We also pointed out how the changes in architecture Intel had introduced with the Nehalem line of processors had dramatically changed the available bandwidth per core, and what a leap forward we had seen in the performance of typical applications.

Paving the Road to Exascale - Part 1 of many

1996 was the year when the world saw the first TeraFLOPS system. 12 years after, the first PetaFLOPS system was built. It took the HPC world 12 years to increase the performance by a factor of 1000. Exascale computing, another performance jump by a factor of 1000 will not take another 12 years.
