Subject: perf-stat per thread results

Hi all,

I'm using perf-stat to look at hardware performance counters for a
parallel program. Is there a way to get counter values for each thread
individually, rather than aggregated for the whole process? I know I
can attach to a specific thread using --tid=, but due to the time
required to find the tid and attach/detach this isn't accurate for
short-running programs.
Or, alternatively, can I use perf record --stat and get an exact count
for each performance counter?

Thanks,
