- the new gcc 3.2 with -march=pentium4 -O3 speeds up my dynamic-system
simulations by 5 to 15 percent, congratulations!
But should we not also optimize the math library and the Xlib library? Is
there any Pentium-4 optimized library?
Incidentally, the newer Athlons still beat the Pentium 4 in our scientific
applications, probabl because Pentium 4's long pipelines stall on bad branch
predictions.
Thanks for any information on library improvements - GAK
