Hi Jirka And how can you control the output for perf stat, if I don't want to use the "sleep" workload, like some user programs. I want to check the "cycles" for this program when it just begin to run.
root@node10:/home$ gcc -g -o malloc malloc.c root@node10:/home$ ./perf stat -e cycles -I 1000 --times-print 3 ./malloc & [1] 32586 # time counts unit events 1.000094153 2,914,162,979 cycles 2.000323667 3,062,832,799 cycles 3.000443807 3,063,146,609 cycles
Best wishes
