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.
