Re: [Gems-users] instruction count in different GEMS protocols?

[Dan Gibson <degibson@xxxxxxxx>]

You should expect instruction count to vary widely even with the same protocol for different RANDOM_SEED, because of spinloops.

hi all,

I am running splash specs in MESI_SCMP and MOESI_SMP and observing the
following: Ruby_cycles are in the same order of magnitute (+- 20%).
However, instructions in MOESI_SMP = (~800%) instructions in
MESI_SCMP.  How can the same specs with the same inputs generate 8x
more instructions in a different protocol? (roughly the same
proportion for all splash specs). Is the variable
*instruction_executed* trustworthy? Should I use another variable to
measure instruction count?

thanks,
Kostas
