Titan Supercomputer Powers the Future of Forecasting

Knowing how the weather will behave in the near future is indispensable for countless human endeavors. Now, researchers at ECMWF are leveraging the computational power of the Titan supercomputer at Oak Ridge to improve weather forecasting.

Radio Free HPC Looks at Supercomputing Global Flood Maps

In this podcast, the Radio Free HPC team looks at how the KatRisk startup is using GPUs on the Titan supercomputer to calculate global flood maps. “KatRisk develops event-based probabilistic models to quantify portfolio aggregate losses and exceeding probability curves. Their goal is to develop models that fully correlate all sources of flood loss including explicit consideration of tropical cyclone rainfall and storm surge.”

Podcast: Supercomputing Flood Maps Using the Titan Supercomputer

In this NPR podcast, Dag Lohmann describes how his startup company called KatRisk is using the Titan supercomputer at ORNL to create detailed flood maps for use by insurance companies.

Video: Porting Physics Apps to Titan with OpenACC

In this video, Aaron Vose from Cray presents: Porting Computational Physics Applications to the Titan Supercomputer with OpenACC and OpenMP.

Attacking HIV with Titan and Blue Waters

“The highly parallel molecular dynamics code NAMD was was one of the first codes to run on a GPU cluster when G80 and CUDA were introduced in 2007, and is now used to perform petascale biomolecular simulations, including a 64-million-atom model of the HIV virus capsid, on the GPU-accelerated Cray XK7 Blue Waters and ORNL Titan machines.”

HPC News Roundup for Friday the 13th

As we pack our bags for a series of Springtime HPC conferences, it’s time to clear the decks and point to some notable news items from this week that didn’t make it to the front page.

Using the Titan Supercomputer to find Alternatives to Rare Earth Magnets

Over at ORNL, Katie Elyce Jones writes that the US Department of Energy (DOE) is mining for alternatives to rare earth magnetic material, an obviously scarce resource. For manufacturers of electric motors and other devices, procuring these materials involves environmental concerns from mining rare earth metals, their costs, and an unpredictable supply chain.
