I am very sorry for the prior message which is sent accidentally during
writing.
I used perf_examples/task.c and performed the following simple measurement
for 'ls' command several times.
./task ls -e "BR_INST_RETIRED"
686804 BR_INST_RETIRED <-- first execution
686803 BR_INST_RETIRED <-- second execution
686805 BR_INST_RETIRED <-- third execution
.
./task ls -e "MEM_STORE_RETIRED"
226 MEM_STORE_RETIRED
250 MEM_STORE_RETIRED
217 MEM_STORE_RETIRED
./task ls -e "INST_RETIRED"
2830093 INST_RETIRED
2830099 INST_RETIRED
2830097 INST_RETIRED
On the other hand, "inst_retired:stores" on core2duo always gave me the same
number.

Download Intel® Parallel Studio Eval
Try the new software tools for yourself. Speed compiling, find bugs
proactively, and fine-tune applications for parallel performance.
See why Intel Parallel Studio got high marks during beta.
