amplxe-runss for cache misses L3 data analysis

Hi

I am looking to analyze caches misses L3 through VTune using the amplxe-runss command line.

I founf this option in some slide but i dont know how to use it (3rd Level Misses ):

((MEM_LOAD_RETIRED.LLC_MISS*180) / CPU_CLK_UNHALTED.THREAD) * 100

any idea/ script?

Thanks,

Mourad

Set environment VTune(TM) Amplifier XE environment, first:

# source vtune_amplifier_xe_2013/amplxe-vars.sh

Intel(R) VTune(TM) Amplifier XE 2013 (build 305106)

# amplxe-runss -event-list | grep MEM_LOAD_   // Use this to know supported memory load events in your platform, then find LLC miss events

//My case - use precise event

# amplxe-runss -event-config=MEM_LOAD_UOPS_MISC_RETIRED.LLC_MISS_PS,CPU_CLK_UNHALTED.THREAD -- ./primes.icc

There will be new result directory generated under current folder. You can use amplxe-gui to open this result, or use command, such as:

# amplxe-cl -report hw-events -r r019
