Most of the applications are fine when compiled with the -ffast-math compiler flag, which makes floating-point computations faster at the expense of some precision loss. However, in the scientific domain, floating-point precision is important so most of the time those codebases are compiled without this option. Still, the question of performance of such code remains […]

Run your floating-point calculations with both precision and speed
One of our customers has a mathematical simulation program where precision matters. We were given the code for evaluation and asked to make it run faster. They have a strict requirement that the source code is compiled without any optimization flags that can influence precision. Most compilers offer a fast-math compiler flag that significantly improves […]
