# # hot-cpu class stressors: # various options have been commented out, one can remove the # proceeding comment to enable these options if required. # # run the following tests in parallel or sequentially # run sequential # run parallel # # aggressive: # enables more file, cache and memory aggressive options. This may # slow tests down, increase latencies and reduce the number of # bogo ops as well as changing the balance of user time vs system # time used depending on the type of stressor being used. # aggressive # # ignite-cpu: # alter kernel controls to try and maximize the CPU. This requires # root privilege to alter various /sys interface controls. Cur‐ # rently this only works for Intel P-State enabled x86 systems on # Linux. # ignite-cpu # # verbose # show all debug, warnings and normal information output. # #verbose # # run each of the tests for 60 seconds # stop stress test after N seconds. One can also specify the units # of time in seconds, minutes, hours, days or years with the suf‐ # fix s, m, h, d or y. # timeout 1m # # times # show the cumulative user and system times of all the child pro‐ # cesses at the end of the stress run. The percentage of utilisa‐ # tion of available CPU time is also calculated from the number of # on-line CPUs in the system. # times # tz # collect temperatures from the available thermal zones on the # machine (Linux only). Some devices may have one or more thermal # zones, where as others may have none. tz # # per stressor options start here # # # cpu stressor options: # start N workers exercising the CPU by sequentially working # through all the different CPU stress methods. Instead of exer‐ # cising all the CPU stress methods, one can specify a specific # CPU stress method with the --cpu-method option. # cpu 0 # 0 means 1 stressor per CPU # cpu-ops 1000000 # stop after 1000000 bogo ops # cpu-load 90% # load CPUs at 90% # cpu-load-slice 50 # 50ms per slice # cpu-method all # use all cpu stressor methods matrix 0 # 0 means 1 stressor per CPU # matrix-ops 1000000 # stop after 1000000 bogo ops # matrix-method all # use all matrix stressor methods # matrix size 65536 # size of N x N matrix
