Compliation flags
Hey, is there a certain reason why e.g. the kmeans_openmp benchmark is compiled and linked with -g and -O2, when best performance should be expected without -g and with -O3?
Makefile
Hi, sorry that I never ran these openmp benchmarks by myself, but I'd say that O3 optimization is faster in general. Some algorithms and data structures may fail the higher-degree optimization.
I suggest search for the cases where O3 is slower and check whether the pattern appears in this benchmark.
