The march document has the following processor name:
broadwell
I mean: The initial letter is lowercase, while inxi’s result is capitalized. Which one should I use?
As for -march=native
, I noticed intel has xHost
code generation option, which is similar to the function of -march=native
. But as we have discussed here, -xHOST
doesn’t work for some vasp tests.
BTW, the following gcc command confirms that -march=native
is equivalent to -march=broadwell
on my machine:
$ gcc -march=native -Q --help=target|grep -- '^[ ]*-march='
-march= broadwell
