[Gems-users] Memory Request Latency vs. CPI

["Carole-Jean Wu" <carolewu@xxxxxxxxxxxxx>]

Hello GEMS-users,

I am running into a strange situation when simulating a multiprogrammed environment. To make the long story short, 

in Sequencer.C's issueRequest, I am adding additional latency to "latency" to mimic e.g. a cache hit, latency+=10 and a cache miss, latency+=100. However, when running two applications with great differences on miss ratio, I've find the same CPI in the ruby0.dumpstat file. 

Can someone explain to me what is going wrong? Am I inserting this additional latency in the wrong place?


Any help is greatly appreciated!

Thanks a lot,
Carole
