Race for supercomputers, now leads the Chinese system with a capacity of 2 Tianhe 33.86 petaflops. Fujitsu's contribution is a rather big deal. Today's fourth performance system in the world - a supercomputer K (11,28 petaflops) - is based on the eight-processor SPARC64 VIIIfx. At the Hot Chips conference in 2014 the company will talk about solutions, senior two generations - up to 32-core processor SPARC64 XIfx (current models of processors Fujitsu - SPARC64 IXfx). According to preliminary data, the company will be able to develop the performance of one teraflop processor - that's four times faster than it predecessor.
Shelf computer 2U chassis can accommodate 12 processor SPARC64 XIfx, which gives 384 core in the case of a single server. It is interesting that each processor has two cores, an assistant whose functions have not yet been disclosed. As the memory system selected solution Hybrid Memory Cube of Micron. Cubes of stack memory Micron's 15 times faster than DDR3 memory with up to 70% more economical consumption. Interprocessor interface will also undergo change. In place of the interface Tofu 1 interface goes Tofu 2. exchange rate increased by approximately 2.5-fold to 12.5 GB / s. Also, the new interface will be built into the processor and controllers, while the first version was implemented as a separate discrete solutions.
Mainframes and platform for them are currently experiencing the worst times in its history, but the developers still do not want to give up.
