I have a problem with some events, which show up on my list of native events using "papi_native_avail". These are:
- Code: Select all
RS_UOPS_DISPATCHED #Total UOPS dispatched to execution ujits
UOPS_RETIRED #Total UOPS retired
X87_OPS_RETIRED #x87 operations
The problem is that whenever i try to count any of the above, i get an error message like:
PAPI error from PAPI_add_events, -8, PAPI_ECNFLCT
I'm working on an Intel Xeon (Quad-Core) running linux ubuntu.
I really need to count micro-ops. Any help is really appreciated.
