According to NVIDIA forecasts, to 2017 the company will develop the components for computer, capable of reaching productivity level in one hexaflops (1018 operations per second). For the moment for similar speed level can dream only powerful supers-computer.
At the international conference on supers-computer ISC in Germany Intel representatives divided their successes in the advance of calculations accelerators. Now multi-core solutions with 512- bit blocks of vector calculations work as good acceleration calculator.
The first generation of accelerators knights ferry did not enter on sale, but it was extended among intel partners as engineering sample. The processor aubrey isle with 32 core, which forms part of knights ferry, does not support double precision floating-point calculations and openCL standard, but its follower knights corner will correct this.
According to intel documents , knights ferry works at 1200/3000 MHz frequencies, if we deal about the revision C0, and at 1200/3600 MHz frequencies, if we deal with the revision D0. In both cases the GDDR5 capacity is equal to 2 Gb. The solution under the code name knights corner will be released on 22 nm technology with the use of three-dimensional transistors structure, more than 50 cores will be located on one crystal. According to some data, the release Of knights corner will start already in this year.
In the benchmark SGEMM the existing knights ferry demonstrate the level speed of one teraflop. The most powerful accelerator tesla in this form of tests collects 800-900 gigaflops, but in 2012 NVIDIA will present the solutions with kepler architecture , which will triple the accelerators calculations speed . Knights corner must possess two times higher productivity in comparison with predecessor. We will not forget, that intel solutions are based on x86- compatible architecture : this simplifies the labor of developers on the optimization of majority of programs under the new accelerators.
According to the forecasts Of intel, to 2015 the speed of most productive super-computer in the world will reach 100 petaflops. Related Products :
