1.2 cooling state 可以认为是温控调节的下一目标的索引,以频率调整为例,state =1 对应100MHZ,state=2表示200MHZ,即通过该值可以找到目标频率,如果是其他方法类似 ,对应策略为降压降频,同时监控周期缩短 Critical: temperature > 80°C,对应策略一般为重启系统 2、Governor实现介绍 step_wise 算法在计算 target cooling step_wise governor 对于 cooling_state 选择的策略: 1)当前温度大于当前trip point时 a. if the trend is THERMAL_TREND_RAISING , use higher cooling state for this trip point b. if the trend is THERMAL_TREND_DROPPING, do nothing the trend is THERMAL_TREND_RAISING, do nothing b. if the trend is THERMAL_TREND_DROPPING, use lower cooling

Power Allocator Power Allocator负责将PID Controller计算出的Power在各个Cooling device进行分配。 分配基于Cooling device需求的功耗Prequest_i、cooling device的权重Wi进行。 首先,计算所以cooling device需求功耗的加权和: 然后,计算各个cooling device按权重应该分得的power: 但是如果某个cooling device获取的Pgranted_i 大于该cooling device实际支持的最大功耗Pmax_i,则其最多只能获取Pmax_i,这样就多分配了Pextra_i = Pgranted_i — Pmax_i,累计所有多分配的power: 最后再将Pextra进行再分配,分配的权重为Wextra_i = 那么再分配得到的功耗Pextra_granted_i= Wextra_i * Pextra 最终每个cooling device所得到的

“对抗扰动生成器”,该方法名为Cooling-Shrinking Attack。 如果我们能熄灭(Cooling)热力图,那么跟踪器将无法定位目标;如果我们能把修正量变得很小,那么跟踪器预测的边界框就会变小(Shrinking),无法准确地框住目标。 本文正是从以上两个角度入手,提出了名为Cooling-Shrinking Attack的攻击方法。 【Cooling-Shrinking Attack】 受论文[5]的启发,我们将“添加对抗噪声”建模成了一个“图像到图像的转换问题”(image-to-image translation)。 这两条期望分别是通过Cooling-Loss跟Shrinking-Loss来实现的,两个Loss的具体形式如下图所示: 但是只有这些还不够,因为对抗攻击的一个基本要求是:添加的噪声要尽可能地不易察觉!
