At 20 petaflops, Titan would be significantly more powerful than the current Top 500 champ, the Sequoia supercomputer at Lawrence Livermore National Labs, which clocks in at 16.3 petaflops.
Data Center Knowledge - “We envision two systems beyond Titan to achieve exascale performance by about 2018,” wrote Jeff Nichols, Associate Laboratory Director for Computing and Computational Sciences. “The first will be an order of magnitude more powerful than Titan, in the range of 200 petaflops. This system will be an exascale prototype, incorporating many of the hardware approaches that will be incorporated at the exascale. We hope to scale this solution up to the exascale.”
InfoWorld - The 100 petaflop Tianhe-2 supercomputer, slated to be deployed in 2015, could help keep China competitive with the future supercomputers of other countries.
The European Union, Japan and the U.S. have similar [100 petaflop] ambitions, said Jack Dongarra, a computer scientist at the University of Tennessee who also compiles the list of the world's top 500 supercomputers.
Commercial Cray XK7 can scale to 50 petaflops
The Cray XK7 system features the latest production hybrid supercomputing technologies. By combining the features of the proven high performance Gemini interconnect, the new NVIDIA Tesla K20 GPUs and the 16-core AMD Opteron processors, the Cray XK7 system is capable of scaling to more than 50 petaflops of performance.
The Cray XK7 supercomputer also features a unified CPU/GPU programming environment that provides users with validated tools, libraries, compilers and third-party software, fully integrated with the system's hardware. When combined with the Cray Linux Environment, the result is a hybrid supercomputer that blends scalable hardware, software and network. Cray XK7 customers will be able to utilize the capabilities of a multi-purpose supercomputer designed for the next-generation of many-core, HPC applications.
