gcc math functions for OpenMP vectoization

2020-06-05 Thread Feltgen, Eric
Hi there, my name is Eric, I'm a german student at RWTH Aachen University currently researching OpenMP. For my research, I'm also looking at math functions provided by compilers like GCC. When writing vectorizable code, it is important to use math functions which also allow for vectorization
