Thanks a lot !


The results will probably improve a little if you will run the script so:


CFLAGS="-march=haswell -O3 -fomit-frame-pointer" ./runbench


It seems that until better compilers will be released, compiling for Haswell gives better results than compiling for any older AMD CPU.


The results will not improve much because most of the work is done inside libgmp, so a version of libgmp that would detect Zen would be necessary for best results.
