                              The deviation is subject to the influence of the machine.
  -l,--loop INT:INT in [1 - 99999]
                              The number of test loop, each loop takes approximately 2 minutes, or the time specified by --time. (default: 1)

运行压力测试,不指定设备时默认测试所有设备,可以通过-i指定设备的index。测试的循环次数和一次的时间可以通过-l-t指定,默认执行一次循环,一次循环持续2分钟。若需要测试一小时,那么可以指定-l 30或者-t 60

运行的前一分钟,会先让设备预热,不会监控设备状态。一分钟后,会监控设备的温度、功率和利用率,每隔一秒刷新一次,同时还会在当前目录下生成 mx-qual-stress.log 文件,可以用于后续分析。压测完成后,会输出压测过程中的整体信息。

测试命令示例:

# 压测2分钟
mx-qual stress
# 压测60分钟
mx-qual stress -l 30
