Yeah, the faster one was atomic. Apparently my copy/paste didn't get
the right thing.

I sort of understand, but I don't really get why
ARM_FS/tests/opt/long/10.linux-boot/arm/linux/realview-o3/ shows up
twice. Was one of them atomic?
Could you run a ARM_SE benchmark like
parser or something?
Thanks,
Ali

Oh, sorry, poor choice of label. Compile time

the decision about SE vs. FS mode is made. It
might be informative to
look at build time too.

Cool, thanks for doing
this. What kind of machine is this on (particularly how many cores)? I'd
be interested in seeing the time it takes for a from-scratch compile
using a single core (say X86_FS/gem5.opt) just to get a clearer measure
of the additional work. Thanks, Steve On Wed, Jan 18, 2012 at 6:07 AM,

runtime performed better than choosing it at compile time on ARM_FS,
although there was more overhead on X86_SE. I'm not really sure why
that's happening. It could be an SE vs. FS thing somehow. Gabe
