Sorry to ask a stupid question. We have a 4P Intel Xeon E5-4620 CPU (Sandy Bridge), and we want to use vtune to moniter some hardware events in the packege. Our motherboard is Dell R720. So, where can we get the events that can be sampled with vtune-update5? I have seen a list in the last section of http://software.intel.com/sites/products/documentation/doclib/stdxe/2013...
But a lot of events that claimed to be supported in Xeon processors cannot be sampled. For example, when run
amplxe-cl -collect-with runsa -knob event-config="SNOOP_RESPONSE.HIT" ls -alrt
I get
amplxe: Error: Invalid Event SNOOP_RESPONSE.HIT discarded.
However, I succeeded once with "OFFCORE_RESPONSE.PF_L2_DATA_RD.LLC_MISS.ANY_RESPONSE_0" event. But I have tried several others and get the same "invaild event" response, like OFFCORE_RESPONSE_0.DATA_IFETCH.LLC_MISS_LOCAL_DRAM, MEM_LOAD_UOPS_MISC_RETIRED.LLC_MISS etc.
The purpose of my test is to using "OFFCORE_RESPONSE_0" with snoop filter to moniter the snoop traffic between CPUs. The method to sample OFFCORE_RESPONSE_0 event is as section 18.8.5 in http://download.intel.com/products/processor/manual/325462.pdf
But what is way to utilize this method in vtune?
I also made sure that there was only one instance of vtune running in the system. So where can we get the valid event list or how can we construct the righ event for moniter?
Thanks a lot!
