The cpufreq line lists the key settings of the CPU clock freqency scaling sub-system of the Linux kernel (see kernel docu). Usually inquired with the cpufreq-info command.

The eff. CPU clock value is an estmate of the average CPU clock used during the execution of the s370_perf jobs. On Intel based systems in general obtained from /proc/cpuinfo via

  cat /proc/cpuinfo | grep MHz

On AMD based systems /proc/cpuinfo in general does not return reliable CPU clock values, on those systems

  sudo cpupower monitor

was used.

The ASM step line contains a summary, generated with hercjsu using -asum, of the ASM steps of the s370_perf jobs with

  • median value of CPU time
  • 50% width of CPU time distribution
  • ratio of CPU time to elapsed time

The GO step line contains a summary, generated with hercjsu using -asum, of the GO steps of the s370_perf jobs with

  • median value of CPU time
  • 50% width of CPU time distribution
  • ratio of CPU time to elapsed time

The lmark value is a MIPS rating generated with the s370_perf_mark tool using the lmix instruction mix.
