The streets of downtown Austin, just cleared of music festival attendees and auto racing fans, are now filled with enthusiasts of a different sort. This year the city is host to SC15, the largest event for supercomputing systems and software, and AMD is on site to meet with customers and technology partners.  The hardware is here, of course, including industry-leading AMD FirePro™ graphics and the upcoming AMD Opteron™ A1100 64-bit ARM® processor. However, the big story for AMD at the show this year is the Boltzmann Initiative, delivering new software tools to take advantage of the processing power of our products, including those on the future roadmap, like the new “Zen” x86 CPU core coming next year.  Ludwig Boltzmann was a theoretical physicist and mathematician who developed critical formulas for predicting the behavior of different forms of matter. Today, these calculations are central to work done by the scientific and engineering communities we are targeting with these tools.
 

Finally, for applications already developed in CUDA, they can now be ported into C++. This is achieved using the new Heterogeneous-computing Interface for Programmers (HIP) tool that ports CUDA runtime APIs into C++ code. AMD testing shows that in many cases 90 percent or more of CUDA code can be automatically converted into C++ by HIP. The remainder will require manual programming, but this should take a matter of days, not months as before. Once ported, the application could run on a variety of underlying hardware, and enhancements could be made directly through C++. The overall effect would enable greater platform flexibility and reduced development time and cost.
