[Gems-users] big CPI?

[pathscale <pathscale@xxxxxxx>]

 Hi,

I'm using unmodified ruby to run a test with SPEC 2006 429.mcf on a 4-core MSI_MOSI_CMP_directory system

But I got a big CPI for CPU3, it's 37!!

What's the reason for that? the config is default config with CPU frequency 1.5G and 4G memory

 

 I attached data below:

 

 

 

 

Virtual_time_in_seconds: 6515.99
Virtual_time_in_minutes: 108.6
Virtual_time_in_hours:   1.81
Virtual_time_in_days:    1.81
 
Ruby_current_time: 50000000
Ruby_start_time: 1
Ruby_cycles: 49999999
 
Total_misses: 37056
total_misses: 37056 [ 3141 1198 1221 31496 ]
user_misses: 30654 [ 0 0 0 30654 ]
