Re: [Gems-users] High IFETCH ratio

[Dan Gibson <degibson@xxxxxxxx>]

I would be worried if IFETCH wasn't quite high... seeing as every LD or ST requires an IFETCH... as do all the non-memory instructions.

Hi,

I collected traces from (parallel sections only) my SPLASH2 runs.
Couple of the benchmarks (namely Barnes-16k and raytrace) show 40%
IFETCH count and pretty much ~1% STORE count and the rest is LOADs. Is
having this large IFETCH counts normal, as the rest of the suite has
less than 1% ratio for IFETCH events?

Regards,

Ed
