Green HPC: a look beyond the hype” is a new, eight-part podcast series from insideHPC that examines green initiatives from all sides of the HPC ecosystem. In episode 1, “Sifting through the hype,” ALD Horst Simon joins Wu-chun Feng of the Green500, Wilf Pinfold of Intel, and Dan Reed of Microsoft Research to discuss how the Green HPC conversation has evolved and why energy consumption is an issue everyone should be concerned about.

NERSC officially accepted a series of upgrades to its Cray XT4 supercomputer, providing the facility's 3,000 users with twice as many processor cores and an expanded file system for scientific research. As a result, the amount of available computing time roughly doubled for scientists studying everything from global climate change to atomic nuclei. More>
Most network traffic is transmitted on a “best effort” basis, meaning that there's a pretty good chance the packets will arrive as intended. But for the Department of Energy (DOE) researchers around the world who are sharing massive scientific datasets, the “best” just isn't good enough. Now, researchers can reserve bandwidth on Energy Sciences Network's (ESnet) circuit-oriented Science Data Network, with the On-Demand Secure Circuit and Advance Reservation System (OSCARS). More>

Cecilia Aragon, staff scientist in the Lawrence Berkeley National Laboratory's Computational Research Division (CRD) was honored with the Presidential Early Career Award for Scientists and Engineers (PECASE), the U.S. government's most prestigious award for early-career scientists. More>
This month, the Department of Energy's (DOE) National Energy Research Scientific Computing Center (NERSC) hosted the first workshop that discussed strategies for managing and storing the influx of new archival data that will be produced in the exascale era, when supercomputers will be capable of achieving quintillions (1,000 quadrillion) of calculations per second. Experts predict that DOE's first exascale supercomputer for scientific research will be deployed in 2018. More>
