What Comes After Moore’s Law And Dennard Scaling?


For decades, Moore’s Law has been an important semiconductor industry mainstay that has helped fuel a relentless progression in computing performance. However, most industry experts agree that Moore’s Law is waning, with an end on the horizon due to a combination of physical limitations and economic factors. With the loss of Dennard Scaling roughly 10 years ago, the industry is at a critica... » read more

Constructing The Pillars Of The ARM HPC Ecosystem


In talking with HPC users at SC15 following the announcement of the OpenHPC project, I consistently heard that while they valued having a common open source framework covering a baseline set of HPC codes, they wanted to see more than one chip architecture represented. This is important when you consider that many HPC users are focused on getting to exascale computing for future supercomputer de... » read more

Cloud Computing Best Practices For Engineering Simulations


Rapid growth in the use of engineering simulation tools – and in the demand for high performance computing (HPC) – is driving interest in cloud computing. Using the cloud for simulation presents unique challenges with different solution types required for specific use cases. This white paper describes eight best practices for cloud deployments that are fundamentally related to simulation... » read more

Power/Performance Bits: Aug. 30


Scalable data center chip Princeton University researchers designed a new scalable chip specifically for data centers and massive computing systems. The team believes the chip, called Piton, can substantially increase processing speed while slashing energy needs. The chip architecture is scalable; designs can be built that go from a dozen cores to several thousand. Also, the architecture ... » read more

Rethinking Big Iron


By Ann Steffora Mutschler One size does not fit all when it comes to the server market, and that may be the best option for low-power processor makers to gain a toehold in a world that until now has been almost laser-focused on performance. Even higher-performance versions of low-power processing architectures are starting to show up inside of datacenters. Many are application-specific ... » read more
