Video: First Galaxies and Quasars in the BlueTides Simulation

Figure 1 from The BlueTides Simulation paper; reproduced with permission; 
z = 8 refers to a redshift of 8 when the universe was a little over 1/2 billion years old.

“BlueTides has successfully used essentially the entire set of XE6 nodes on the Blue Waters. It follows the evolution of 0.7 trillion particles in a large volume of the universe (600 co-moving Mpc on a side) over the first billion years of the universe’s evolution with a dynamic range of 6 (12) orders of magnitude in space (mass). This makes BlueTides by far the largest cosmological hydrodynamic simulation ever run.”

In this video, Dan Olds from Gabriel Consulting and Brian Sparks from the HPC Advisory Council discuss the competitors in the upcoming ISC 2015 Student Cluster Competition. Located on the exhibit floor at ISC 2015, the competition kicks off July 13 in Frankfurt.

Call for Posters: New York Scientific Data Summit

NYSDS15_poster

“This annual meeting aims to accelerate data-driven discovery and innovation by bringing together researchers, developers and end-users from academia, industry, utilities and state and federal governments. Jointly organized by Brookhaven National Laboratory (BNL), Stony Brook University (SBU), and New York University (NYU) the theme of this year’s conference is “Frontiers in Scientific Data.”

Simulating Geomagnetic Storm Effects on Power Grids

“Using Blue Waters, we are for the first time running highly detailed, global simulations of the Earth-ionosphere waveguide under the effect of a geomagnetic storm. Disturbed ionospheric currents are modeled in a three-dimensional Maxwell’s equations finite-difference time-domain (FDTD) model extending from -400 km to an altitude of 400 km.”

Video: Three Ways to Debug Parallel CUDA Applications

0

“This talk will introduce these three debugging techniques and provide some suggestions on selecting the optimal approach for a variety of debugging scenarios such as hangs, numerical errors, and crashes. Specific examples will be given using the TotalView debugger but the concepts covered may apply to other debugging tools such as GDB and the NVIDIA NSIGHT debugger.”

“This radical new approach will fuse memory and storage, flatten data hierarchies, bring processing closer to data, embed security throughout the hardware and software stacks and enable management of the system at scale. Learn more by joining a panel of senior HP Labs researchers working on The Machine as they offer a closer look at what it takes to make it happen.”
