二、使用示例:
[buildroot@root ~]# stress-ng --cpu 0 --tz -t 60
stress-ng: info: [9331] dispatching hogs: 2 cpu
stress-ng: info: [9331] cache allocate: using built-in defaults as unable to determine cache details
stress-ng: info: [9331] cache allocate: default cache size: 2048K
stress-ng: info: [9331] successful run completed in 60.05s (1 min, 0.05 secs)
stress-ng: info: [9331] cpu:
stress-ng: info: [9331] imx_thermal_zone 57.57 °C
[buildroot@root ~]# stress-ng --matrix 1 -t 1m
stress-ng: info: [9490] dispatching hogs: 1 matrix
stress-ng: info: [9490] cache allocate: using built-in defaults as unable to determine cache details
stress-ng: info: [9490] cache allocate: default cache size: 2048K
stress-ng: info: [9490] successful run completed in 60.00s (1 min, 0.00 secs)
