Using the Titan Supercomputer to find Alternatives to Rare Earth Magnets

Simulations could uncover competitive substitutes for these super strong 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.

Titan Supercomputer Powers Semiconductor Research


Researchers studying iron-based superconductors are combining novel electronic structure algorithms with the power of the Titan supercomputer at ORNL to predict spin dynamics, or the ways electrons orient and correlate their spins in a material.

Video: Large Scale Debugging on Titan and Mira with Allinea DDT


In this video from the 2014 Argonne Training Program on Extreme-Scale Computing, David Lecomber presents: Large Scale Debugging on Titan and Mira with Allinea DDT.

Move Over Jaguar, Titan Supercomputer Tops in Energy Efficiency


When the Oak Ridge Leadership Computing Facility (OLCF) replaced its Jaguar supercomputer with Titan, not only did it expand its computing speed tenfold, it also saved on the electric bill.

Tiny Titan Supercomputer Headed for Schools


In this video, students get hands-on experience with a scaled-down version of the Titan supercomputer. Constructed at Oak Ridge National Laboratory, Tiny Titan is a nine-node scale-model of Titan designed to make it easier for students to understand how a supercomputer works.

Titan Supercomputer Users Enjoy Increased Stability


Jeff Gary writes that the Oak Ridge Leadership Computing Facility’s Titan supercomputer has overcome a challenging launch and is now showing impressive stability.

New Paper: Petascale Multiphase Flow Solutions on Titan Supercomputer


“In this paper, we consider a coupled solution in which a multiphase flow simulator is coupled to an analysis approach used to extract the interfacial geometries as the flow evolves. This has been implemented using MPI to target heterogeneous nodes equipped with GPUs. The GPUs evolve the multiphase flow solution using the lattice Boltzmann method while the CPUs compute upscaled measures of the morphology and topology of the phase distributions and their rate of evolution. Our approach is demonstrated to scale to 4,096 GPUs and 65,536 CPU cores to achieve a maximum performance of 244,754 million-lattice-node updates per second (MLUPS) in double precision execution on Titan.”

CORAL Seeks Proposals for Mira, Sequoia, and Titan Follow-on Supercomputers


As a three-way collaboration, the CORAL project is collaborative DOE effort to replace today’s Sequoia, Titan, and Mira supercomputers. In this video, LLNL CTO Bronis R. de Supinski describes the objectives of CORAL and how it will lead to Livermore’s next-generation supercomputer.

Earthquake Simulations on Titan Make for Safer Buildings

Researchers at the Southern California Earthquake Centre (SCEC) used ORNL’s Titan machine to simulate a major earthquake at high frequencies up to 10Hz. The calculations will give structural engineers the data required to make predictions about the scale of the damage to buildings caused by the next big earthquake to hit the San Andreas Fault.

GPU-Powered Titan Supercomputer Simulates Molecular Switch that Controls Cells


Researchers are using the GPU-powered Titan supercomputer to study a key molecular switch that controls cell behavior. Scientists want to manipulate cell behavior for a lot of reasons. If they can control cell functions such as movement and development, they can cripple cells and pathogens that are causing disease in the body.
