[Gems-users] IPC and Ruby cycles

Subject: [Gems-users] IPC and Ruby cycles
Dear list,
 
I noticed that with SIMICS_RUBY_MULTIPLIER set to 2, the Ruby_cycles shown in Ruby stats is always half of the cycle count shown by simics. When calculating the IPC, which cycle count should I use, Ruby_cycles or the cycle count of Simics? I'm quite curious why there is a SIMICS_RUBY_MULTIPLIER parameter and what's its purpose. As always, thanks a lot for your comments!
