The meeting showcased the experiences of researchers who had ported their scientific computing codes to Intel’s Knights Ferry software development platform, as well as those working on the single-chip cloud (SCC).

As of this week, there are 20 known petascale systems deployed, which in aggregate encompass five different varieties of microprocessors. And that level of diversity shows no signs of reversing itself.

The new CPU represents the company’s latest Xeon offering for dual-socket servers, and boasts a number of new features including better performance, a new floating point instruction set in AVX, and integrated I/O.

The Godson-3B and ShenWei SW1600 CPUs were the first out of the gate, with the latter chip powering a Chinese petascale supercomputer. Waiting in the wings is the FeiTeng processor, an architecture that could be the one that takes Chinese supercomputing into the exascale realm.
In May, chip startup Adapteva debuted Epiphany, a manycore architecture designed to maximize floating point horsepower with the lowest possible energy footprint. The initial silicon was a 16-core processor, implemented on the 65nm process node. This week, the company announced it has taped out a 64-core version of the design on the 28nm process node, delivering 100 gigaflops of performance at under 2 watts of power.
GPU maker NVIDIA has ratcheted up the core count and clock speed on its Tesla GPU processor. The new M2090 module for servers delivers 665 double precision gigaflops, representing close to a 30 percent increase over the previous generation Tesla part. The memory bandwidth on the device was bumped up as well, from 150 GB/second to 178 GB/second. The new GPU boosts performance significantly across a number of HPC codes.
