DARPA Power Efficiency Revolution Project targets 75 gigaflops per watt

DARPA’s Power Efficiency Revolution for Embedded Computing Technologies (PERFECT) program seeks to improve power efficiency for embedded computer systems, providing more computing per watt of electrical power. To increase awareness of this program and attract potential researchers, DARPA has scheduled a Proposers’ Day workshop Feb. 15 in Arlington, Virginia.

The goal of 75 GFLOPS/watt would enable a 15 megawatt supercomputer to achieve an EXAFlop of processing.
...
PERFECT aims to achieve the 75 GFLOPS/w goal by taking novel approaches to processing power efficiency. These approaches include near threshold voltage operation and massive heterogeneous processing concurrency, combined with techniques to effectively use the resulting concurrency and tolerate the resulting increased rate of soft errors. The program seeks to leverage and incorporate anticipated industry fabrication geometry advances to 7 nanometers.

az atlasz HPC partíciója (intl E5520) cca 10 kw; és cca 3.2 Tflops.
3200 gflops / 10000 w = 0.32 Gflops/watt.
Ehez képest a 75 Gflops/watt 235-ször hatékonyabb.
Nem lenne rossz.

Ebbe a huteset is beleszamoltad? Mert az meg kb. duplazza a fogyasztast (mikozben a szamitasi teljesitmenyt nem javitja).

Mas kerdes, hogy specialis feladatokra komoly korlatozasokkal, pl. GPGPU-val, HW-es megkozelitessel, meg egyeb hasonlo technikakkal el lehet erni mar mai technikaval is ennel jobb aranyt.
