Scalable clusters make HPC R&D easy as Raspberry Pi

(DOE/Los Alamos National Laboratory) A quest to help the systems software community work on very large supercomputers without having to actually test on them has spawned an affordable, scalable system using thousands of inexpensive Raspberry Pi nodes.

First-ever US experiments at new X-ray facility may lead to better explosive modeling

(DOE/Los Alamos National Laboratory) For the first time in the US, time-resolved small-angle x-ray scattering (TRSAXS) is used to observe ultra-fast carbon clustering and graphite and nanodiamond production in the insensitive explosive Plastic Bonded Explosive (PBX) 9502, potentially leading to better computer models of explosive performance.
