Some HPC kids just can't help piling on the weight

HPC Blog We've saved the biggest for last in our round-up of the ASC16 Student Cluster Competition competitors. All of the teams below are driving clusters with more than nine nodes, most with several GPU accelerators. They're definitely power hungry beasts, which will require the teams to apply heavy throttling in order to stay under …

IBM's 'neurosynaptic chip' to power nuke-watching exascale rig

IBM's TrueNorth platform will form the basis of a collaboration with Lawrence Livermore National Laboratory (LLNL) to chase the exascale dream. The “neurosynaptic chip” Big Blue – or perhaps, given its much-hyped “brain-inspired” design, we should say “Big Grey”? – will “process the equivalent of 16 million neurons and 4 …

Hey kids – want to be an HPC bigshot? Don't have a secret exascale supercomputer?

HPC blog Do you want to secure a place in HPC (high performance computing) history? One route would be to single-handedly design and implement an exascale supercomputer, which most would categorize as "hard". However, an easier route is to participate in the various Student Cluster Competitions (SCCs) that take place around the world. …

This is how you count all the trees on Earth

The Earth has three trillion trees and this is seven times more than was thought, until very recently, to exist. It is also half the number that existed before humanity went to work on the environment. We can deduce this through algorithms used to crunch reams of photographic data captured by satellite. But the headline figure …
