A Trillion Particles
Ho-hum, a billion cells is starting to sound like everyday work. The award-winning best paper from the 2013 Cray User Group described a plasma physics simulation that used over two trillion particles to study “how energetic particles are generated in magnetic reconnection.” The simulation was run on 120,000 cores of the NERSC’s Cray XE6 and generated 350 TB of data. The technical paper (PDF format) is available on the linked site.
Two news items from CEI, makers of EnSight, this week. First, EnSight now features a direct reader for GMV files output by CPFD’s Barracuda virtual reactor software (see image below). This new feature is in addition to the native EnSight case file export already in Barracuda.
CEI has also partnered with zSpace to deliver CFD post-processing through”virtual holographic computing,” a virtual reality technology.

Water Water Everywhere
From empty water (see above) to sonic water. Put a pan of water on top of a speaker, play your favorite music, and project video of the water on a wall and what do you get – Sonic Water. [Any fan of Pink Floyd has seen this type of thing before.]
