Hi Nilton, Thanks a lot for letting me know, and glad that it works for you! :-) Copying the list for archiving purposes...

From the source code, the problem was after calling PAPI_add_events(...) in do_dryrun() in src/libpshwpc/hwpc-papi.c. It looked like PAPI_add_events(...) did not return PAPI_OK, but the code handled only the error case of PAPI_ECNFLCT (counter conflict, i.e., they can not be measured without multiplexing) and the case where events were partially added. > > > > I added a few lines to print more debug info in the hwpc-papi.c file.
