Test description
command perf, response, and accumulation of results in dict Expand source
loop 99/100
command: perf stat -e cache-references,cache-misses,cycles,instructions,branches,faults,migrations sleep 5
Performance counter stats for 'sleep 5':

Command perf with 5sec accumulation time submitted in subprocess one by one in loop, response parameters parsed in dict and preserved in the list. In total, 100 loops are executed for 500 sec. After loop 10 and 50 (twise) host is loaded by the "simulated time consuming job" loading different number of CPUs, which is running for about 2 min or ~20 loops. At the end of the loop plots and table of parameters vs time are generated.
