bus error for custom collection

Hi Intel experts,

 

I'm using the custom collection to get cache hits and misses for the L1, L2, and L3 caches on an image processing program. When I run the command on 50 frames, the collection works, but as soon as I increase it up to 100 frames it throws out "bus error (core dumped)" after amplxe generates 8% of the report. This is the command I'm using:

 

amplxe-cl -collect-with runsa -knob event-config=MEM_LOAD_UOPS_RETIRED.L1_HIT, MEM_LOAD_UOPS_RETIRED.L2_HIT, MEM_LOAD_UOPS_RETIRED.L3_HIT, MEM_LOAD_UOPS_RETIRED.L1_MISS, MEM_LOAD_UOPS_RETIRED.L2_MISS, MEM_LOAD_UOPS_RETIRED.L3_MISS -- ./run.sh

 

Do you know why I would be getting a bus error? I am able to run advanced-hotspots analysis on over 2500 frames so I'm unsure of why this collection wouldn't work on larger sets of data.

I am not sure what you meant, I guess that frame number is your input parameter of program ? Can you please describe it in detail?

Is it possible that you can send private message to me with core dump? What is VTune Amplifier XE version you use?
