Room: C27 3.010 - C27 Ebene 3 Setting expectations

discussion: floating-point and fast-math

• Matthias Kretz (GSI Helmholtzzentrum für Schwerionenforschung GmbH(GSI))

Room: C27 3.010 - C27 Ebene 3 1. we will try to get everybody on the same page: floating-point, special values, standards, optimizations (conforming and non-conforming), correctly rounded vs. room for error 2. we will try to understand what our codes rely on and where we're missing out on optimizations 3. I want to learn from you how to prioritize simd implementation work with regard to floating-point corner cases
