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.

Gordon Bell Finalists Achieve 20 Petaflops on Titan


Researchers are using the GPU-powered Titan supercomputer at record speeds to monitor proteins responsible for cellular behavior. With a sustained performance of 20 petaflops, the application earned the development team from Italy a finalist position for the Gordon Bell Prize.

Gordon Bell Finalist Uses Titan to Power Universe Sky Catalog


Researchers are using the Titan supercomputer to create a comprehensive sky catalog of the development of the universe. The project is a finalist for the 2013 Gordon Bell Prize.

Four Gordon Bell Finalists using GPU-powered Titan Supercomputer


Four of the six finalists for this year’s Gordon Bell Prize conducted their research on the Titan supercomputer.
