execute_perf.sh: "Error opening counter cycles" about sosd

[RyanMarcus]

Hi Ali,

Sorry for the trouble!

I believe the Ubuntu package you need it linux-tools-common. Not sure if that's in the setup script or not.

The default configuration on some distributions restricts perf counter access to superusers. Can you try running the script with sudo?

If none of that works, try just running perf record build/benchmark build/lognormal_200M_uint64 data/lognormal_200M_uint64_equality_lookups_10M to see why perf isn't running on your machine.

Thanks,

Ryan

Are you on a local machine? AWS doesn’t support hardware counters.

Yes, a local machine with Ubuntu 18. Everything works fine except execute_perf.sh.

I suspect there is another package/tool/config required by the perf benchmark that is NOT in setup_anywhere.sh ??

Thanks guys! It works with sudo
