--- Comment #35 from Joost VandeVondele <Joost.VandeVondele at pci dot uzh.ch> 2011-01-25 10:03:02 UTC --- (In reply to comment #34) > -march=native is ambiguous, please see with -v what actually is being used. This was mentioned in the initial comment: -march=k8-sse3 -mcx16 -msahf --param l1-cache-size=64 --param l1-cache-line-size=64 --param l2-cache-size=1024 -mtune=k8 The latest timings are on a newer machine (old one is gone now) which has: -march=amdfam10 -mcx16 -msahf -mpopcnt -mabm --param l1-cache-size=64 --param l1-cache-line-size=64 --param l2-cache-size=512 -mtune=amdfam10
