Problems with some events...

[arrazem]

Hi All:

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.


Thanks

If you see error list you have in -8:"-8, PAPI_ECNFLCT, Hardware event exists, but cannot be counted due to counter resource limitations"

Maybe you have same problem as me, see faq: "My program runs fine when measuring 1 or 2 events, but when I add more I get a -8, PAPI_ECNFLCT error code. The error text says, "Event exists. but cannot be counted due to hardware resource limitations". What does this mean?"

Good luck.

Where do I see this faq??

Thanks

Never mind, I found the FAQ you referred to on the PAPI website; HOWEVER,
they're talking about limitation caused when trying to count more that one event. Here I'm only counting one event, but still get this error.

Any ideas?
