Re: [Gems-users] Which matrices should be used to compare CMP coherence protocols?

What does RUBY_CYCLES say?

Hi,

I am trying to compare the performance of 2 CMP cache coherence protocols by running a benchmark. Could anyone please give me an idea about which matrices from the ruby stats file will be good for performance comparison? Because according to the wiki MOESI_CMP_directory is supposed to give better performance than MSI_MOSI_CMP_directory. But I found that the miss_latency of my run says otherwise.

Thanks,
Lopamudra
