A TOAST for Next Generation CMB Experiments
Computational cosmologists at Berkeley Lab they recently achieved a critical milestone in preparation for upcoming CMB experiments: scaling their data simulation and reduction framework TOAST to run on all 658,784 Intel Knights Landing Xeon Phi processor cores on the NERSC's Cori. The team also implemented a new module to simulate the noise introduced when ground-based telescopes look at the CMB through the atmosphere.

The Wonderland of ALICE: Q&A with Thomas M. Cormier

An experiment called ALICE at the Large Hadron Collider is dedicated to the study of heavy-ion collisions. ALICE stands for 'A Large Ion Collider Experiment.' Its aim is spotting the high-energy, elementary particles, like electrons and gamma rays, streaming from the quark-gluon plasma, to explore the physics of the early universe. Oak Ridge National Laboratory physicist Thomas M. Cormier provides an update on the experiment.

Launching a supercomputer: How to set up some of the world's fastest computers

Setting up a supercomputer is far more complicated than just bringing it home from the electronics store. Staff members of the Department of Energy's supercomputing user facilities spend years on the process, from laying out requirements through troubleshooting. In the end, they run some of the most powerful computers in the world to help solve some of science's biggest problems.

Tackling disease in three dimensions: Supercomputers help decode RNA structure
In collaboration with staff from the Argonne Leadership Computing Facility, researchers at the National Cancer Institute have perfected a technique that accurately computes the 3-D structure of RNA sequences. This method, which relies on a computer program known as RS3D and supercomputer Mira gives researchers studying cancer and other diseases structural insights about associated RNAs that can be used to advance computer-assisted drug design and development.

Will brain-inspired chips make a dent in science's big data problems?
Although neuromorphic computing is still in its infancy, Lawrence Berkeley National Laboratory (Berkeley Lab) researchers hope that these tiny, low-power, brain-inspired computing systems could one day help alleviate some of science's big data challenges. With funding from the Laboratory Directed Research and Development (LDRD) program, two groups of researchers are exploring how science might benefit from this new technology.

A fresh math perspective opens new possibilities for computational chemistry
A new mathematical "shortcut" developed by Berkeley Lab researchers is speeding up molecular absorption calculations by a factor of five, so simulations that used to take 10 to 15 hours to compute can now be done in approximately 2.5 hours. These algorithms will be incorporated in an upcoming release of the widely used NWChem computational chemistry software suite later this year.

Physicists move closer to listening in on sub-atomic conversation
Much like two friendly neighbors getting together to chat over a cup of coffee, the minuscule particles in our sub-atomic world also come together to engage in a kind of conversation. Now, nuclear scientists are developing tools to allow them to listen in on the particles' gab fests and learn more about how they stick together to build our visible universe. The first complex calculations of a particle called the sigma have been carried out and published in Physical Review Letters.
