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 On 19.01.2012 01:59, Gabriel Michael Black wrote: > Oh, sorry, poor choice of label.

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.

I'm not really sure why that's happening. It could be an SE vs. FS thing somehow.
