Fast Numerical Computation in C++ - Expression Templates

Explore the world of expression templates in C++ and their impact on optimizing numerical calculations in this comprehensive conference talk. Delve into the challenges of optimizing numerical computations and understand how expression templates are utilized in popular libraries like Boost's uBLAS, Blitz++, and Armadillo. Examine the limitations of expression templates and discover why "gold standard" numerical libraries like ATLAS and FFTW are not written in C++. Learn about advanced numerical computation frameworks that surpass typical C++-only libraries through complex code generation, hardware adaptation, and extensive benchmarking. Finally, investigate techniques to enhance C++ performance beyond expression templates and gain insights into a new prototype framework demonstrating practical implementation.
