SGER: Dynamic hardware adaptation of high performance CMPs for managing thermal hotspots

CCF - 0649824标题：SGER -用于管理热热点的高性能cmp的动态硬件适配[j]: Kundu， sandipst: University of Massachusetts amherstabstract]随着晶体管尺寸的缩小，单位面积上集成的器件越多，单位面积上芯片的功耗和散热就越高。在处理器上执行的软件程序可以定制为在芯片的特定区域上创建热热点。CMOS电路的性能取决于温度。由热点引起的较大温差往往会导致由于这种温度变化引起的信号竞争而导致功能失效。热点也会导致长期的可靠性问题。在本提案中，我们通过监控软件执行，测量软件执行时温度的变化率，预测潜在问题并通过各种拦截方法（包括电压和频率控制，暂停，切换线程到不同的核心等）来解决多核处理器的这个问题。监控进程在相同的多核处理器上执行，对操作系统或应用程序是隐藏的。该方案实现了对硬件的监控和适配

CCF - 0649824Title: SGER - Dynamic hardware adaptation of high performance CMPs for managing thermal hotspotsPI: Kundu, SandipInst: University of Massachusetts AmherstAbstractAs the transistor dimensions shrink, more devices are integrated per unit area, driving up power consumption and heat dissipation of a chip on a per unit area basis. A software program executing on a processor can be tailored to create a thermal hot spot on a specific area of a chip. Performance of CMOS circuits depends on temperature. Large temperature differentials caused by hot spots often result in functional failures due to signal race introduced by such changes in temperature. Hot spots also cause long term reliability problems. In this proposal, we are addressing this problem for a multi-core processor by monitoring software execution, measuring the rate of change of temperature as the software executes, predicting potential problems and avoiding them by various intercept methods including voltage and frequency control, suspension, switching thread to a different core etc. The monitoring process executes on the same multi-core processors and is hidden from operating systems or applications. This scheme of monitoring and adapting the hardware
