I have encountered the same problem.I am now using AMD too the conflicts events is PAPI_BR_MSP and PAPI_L1_TCM the two events can not be configured in the single xml configuration file.

I have checked the list of supported events from psinv -p against the events listed in the papi3_k8.xml configuration file and all the events in the config file are supported. I also ran psrun -i to ensure that it is using the papi3_k8.xml config file. Attached is the output of psinv -p and also the the config file papi3_k8.xml.

I removed all events from the papi3_k8.xml config file and started adding them back in one by one. Everything works fine with all be events except for PAPI_L1_TCM and PAPI_L2_TCA even though both these events appear in the psinv -p output.

Sounds like some good detective work on your end, thanks for checking into things and reporting. Now, as to why this is going on I have to admit being stumped at the moment. This would seem at first glance to be something going wrong in either the PAPI or perfctr layers. Within the PAPI 3.2.1 distribution there is a utility called "papi_avail" that can print out information about mappings of PAPI events to the native counters that may provide a clue. It's invoked as "papi_avail -e EVENTNAME" where EVENTNAME is the name of the PAPI event one wants more information about. You might try that utility with the events above and see what the output is to get started. Unfortunately, I do not have access to an Opteron with the kernel support required to test this out, but if this limitation is a problem for you we can try to look further into it. Rick p.s. for detailed debugging information, PerfSuite's configure script supports an option --enable-debug and the software recognizes an environment variable PS_DEBUG which if set to 3 or higher will dump a lot of information about what's going on underneath to help locate sources of errors. ------------------------------ Message: 4 Date: Mon, 20 Nov 2006 15:11:50 +0000 From: Niall Moran Subject: Re: [PerfSuite-users] psrun and 2.6 kernel To: Rick Kufrin Cc: per...@li...

Running papi_avail for both these events works fine and says that they pass. I then tried adding both these events and these alone to the config file and it worked fine. It appears that there are conflicts between these events and some of the others. I ran into a similar problem using papi with itc on an itanium2. I will recompile perfsuite with the debugging enabled and will experiment with different configs to try to get an idea of which events are conflicting with which.
