Post by Vince WeaverDoes running something like "perf stat -e cycles /bin/ls" return useful
results?
$ which perf
/usr/bin/perf
$ perf stat -e cycles /bin/ls
<skip ls output>
Performance counter stats for '/bin/ls':
7,463,051 cycles # 0.000 GHz
0.002552476 seconds time elapsed
However, if I add "-v", I get:
newblue4> perf stat -e cycles -v /bin/ls
Old kernel, cannot exclude guest or host samples.
<skip ls output>
cycles: 7384246 2235923 2235923
Performance counter stats for '/bin/ls':
7,384,246 cycles # 0.000 GHz

BTW, PAPI 5.3.0 is available on the system via modules:
libraries/intel_builds/papi-5.3.0.
papi_avail from 5.3 and 5.4 return identical output.
I don't know if this helps:
