Re: [Gems-users] Effect of OPAL_RUBY_MULTIPLIER on CPI

[Dan Gibson <degibson@xxxxxxxx>]

I agree -- this behavior seems odd. As I've said before, I'm no Opal expert, but I'll cover the basics before giving up:
1. Are you changing anything else? (Code or configuration?)
2. What workload are you running?
3. How are you deciding how long to run the simulation? sim-step something-or-other?

Regards,
Dan

Hi,

While running simulations on OPAL + Ruby simulator , on increasing the OPAL_RUBY_MULTIPLIER　value, the CPI　decreases.
Since we make the memory system slower with a higher value of the multiplier, we expected an increase in the CPI. But that does not seem to be the case. Can anyone shed more light on this?
