I am trying to run COMPSs with the tracing system (extrae) activated. I first had an installation issue but I solved it thanks this question:
How to fix libpapi.so.* cannot open shared object file when running (py)COMPSs with tracing?
However, now I am facing a new PAPI problem. The COMPSs runtime seems to be correctly loaded but Extrae reports this errors:
Extrae: Error! Hardware counter PAPI_L3_TCM (0x80000008) cannot be added in set 1 (thread 0)
Extrae: Error! Hardware counter PAPI_FP_INS (0x80000034) cannot be added in set 1 (thread 0)
Extrae: Error! Hardware counter PAPI_SR_INS (0x80000036) cannot be added in set 2 (thread 0)
Extrae: Error! Hardware counter PAPI_BR_UCN (0x8000002a) cannot be added in set 2 (thread 0)
Extrae: Error! Hardware counter PAPI_BR_CN (0x8000002b) cannot be added in set 2 (thread 0)
Extrae: Error! Hardware counter PAPI_VEC_SP (0x80000069) cannot be added in set 2 (thread 0)
Extrae: Error! Hardware counter RESOURCE_STALLS (0x40000023) cannot be added in set 2 (thread 0)
Despite the errors I get:
Extrae: Successfully initiated with 1 tasks and 1 threads
WARNING: IT Properties file is null. Setting default values
[ API] - Deploying COMPSs Runtime v1.4 (build 20160722-1520.r59)
[ API] - Starting COMPSs Runtime v1.4 (build 20160722-1520.r59)
But after starting the runtime I get this in a infinite loop:
Extrae: PAPI_read failed for thread 1 evtset 2 (papi_hwc.c:669)
Extrae: PAPI_read failed for thread 0 evtset 1 (papi_hwc.c:669)
I would like to be able to get traces even if they don't have hardware PAPI counters. How can I disable them or fix the error?
Check and disable unavailable PAPI counters
It appears that you don't have that counters available in your machine. Use:
papi_avail -a
to see the available papi counters. Edit the config files under: /opt/COMPSs/Runtime/configuration/xml/tracing/*.xml and remove the offending PAPI counters from the <counters> section. Alternatively, you can use:
/opt/COMPSs/Dependencies/extrae/bin/papi_best_set COUNTER_NAME_#1, COUNTER_NAME_#2, COUNTER_NAME_#3, ...
to see if there is some incompatibility in the PAPI counter sets.
Disable all counters
If you want to disable all of them just change files:
under /opt/COMPSs/Runtime/configuration/xml/tracing/ folder and change the line:
<counters enabled="yes">
for:
<counters enabled="no">
