Volume rendering of the entropy in a full 3-D GRMHD simulation of a differentially rotating and highly magnetized progenitor to a supernova. Red colors indicate high entropy (hot) material while blue represents low entropy (cold) material. Strongly magnetized material is continously launched from the surface of the proto-neutron star in the center but gets severly distorted such that, instead of a clean jet observed in the ultrastrong magnetic field case, two giant polar lobes are formed. The box size for the visualization is 2000km cubed. GRMHD refers to a general relativistic magentohydronamic simulation.

What's in a Stampede Node?

Stampede has 6,400 Dell C8220 compute nodes that are housed in 160 racks; each node has two Intel E5 8-core (Sandy Bridge) processors and an Intel Xeon Phi 61-core (Knights Corner) coprocessor. Stampede is a multi-use, cyberinfrastructure resource offering large memory, large data transfer, and graphic processor unit (GPU) capabilities for data-intensive, accelerated or visualization computing. To this end, there are also 16 large-memory nodes with 1 terabyte (TB) memory, as well as 128 compute nodes with NVIDIA Kepler K20 GPUs. All components are integrated with an InfiniBand FDR network of Mellanox switches to deliver extreme scalability and high-speed networking.

Picture DNA on Facebook. The image above is a map of links between the genes of the mustard plant Arabidopsis thaliana. Genes involved in the same biological process are connected by lines: red for more certain links, blue for less certain links. "It's not unlike a social network," says biologist Seung Yon Rhee.
