I am trying to use PAPI to check processor events for a college work, but it doesn't show any PAPI Preset Events when use papi_avail -a
After I've already installed libopenmpi-dev, papi-tools and PAPI 7.1.0, the output for papi_avail -a was:
Available PAPI preset and user defined events plus hardware information.--------------------------------------------------------------------------------PAPI version : 7.1.0.0Operating system : Linux 6.5.0-17-genericVendor string and code : GenuineIntel (1, 0x1)Model string and code : 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz (140, 0x8c)CPU revision : 1.000000CPUID : Family/Model/Stepping 6/140/1, 0x06/0x8c/0x01CPU Max MHz : 4700CPU Min MHz : 400Total cores : 8SMT threads per core : 2Cores per socket : 4Sockets : 1Cores per NUMA region : 8NUMA regions : 1Running in a VM : noNumber Hardware Counters : 19Max Multiplex Counters : 384Fast counter read (rdpmc): no--------------------------------------------------------------------------------================================================================================ PAPI Preset Events================================================================================ Name Code Deriv Description (Note)--------------------------------------------------------------------------------Of 0 available events, 0 are derived.No events detected! Check papi_component_avail to find out why.After this I used papi_component_avail and the output was:
Compiled-in components:Name: perf_event Linux perf_event CPU countersName: perf_event_uncore Linux perf_event CPU uncore and northbridge \-> Disabled: No uncore PMUs or events foundName: sysdetect System info detection componentActive components:Name: perf_event Linux perf_event CPU counters Native: 165, Preset: 0, Counters: 19 PMUs supported: ix86arch, perf, perf_raw, iclName: sysdetect System info detection component Native: 0, Preset: 0, Counters: 0So what I need to do to papi detects the processor events?Thanks for any help!
