I am running oprofile on a linux intel haswell machine. and the operf process is taking close to 100% of the time. what is operf doing with that amount of cpu cycles ? maybe its polling on something ? how do i fix this ? operf --separate-thread --event=CPU_CLK_UNHALTED:10000000 ./gcc/bin/viterb00data_2.exe -autogo && opreport -l -g -d --xml -o current.opm top - 15:56:34 up 69 days, 2:59, 13 users, load average: 2.04, 1.71, 1.43 Tasks: 1196 total, 4 running, 1191 sleeping, 1 stopped, 0 zombie Cpu(s): 1.1%us, 0.1%sy, 0.0%ni, 98.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 60853364k total, 39834668k used, 21018696k free, 818524k buffers Swap: 20479992k total, 1428k used, 20478564k free, 34594044k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 755 root 39 19 0 0 0 R 98.3 0.0 6891:01 kipmi0 118201 xintong1 20 0 14448 1700 1412 R 98.3 0.0 0:03.06 operf 118206 xintong1 20 0 15020 660 524 R 98.3 0.0 0:03.06 viterb00data_2.
