"... the result of any execution is the same as if the operations of all the processors were executed in some sequential order, and the operations of each individual processor appear in this sequence in the order specified by its program." 也就是说,要满足Sequential consistency,必需保障每个处...
Sequential consistency的在wiki上的定义如下: "... the result of any execution is the same as if the operations of all the processors were executed in some sequential order, and the operations of each individual processor appear in this sequence in the order specified by its program." 也就是说...
processor.max_cstate=0用描述acpi driver中cpu cstate的最大级别,但是实际max_cstate=0并不能真的让CPU保持在C0态,只能让CPU保持在C1状态。如下代码: Note that intel_idle.max_state = 0 disables intel_idle and lets acpi_idle (processor.max_state) take over. vim /usr/src/debug/kernel-3.10.0-6...
How are response time and throughput affected by Replacing the processor with a faster version? 改善处理器 Adding more processors to do separate tasks? 添加更多的处理器 Queue ?采用排队机制,改善吞吐量 We’ll focus on response time for now… Relative Performance Define Performance = 1/Execution Tim...

The mpstat command writes to standard output activities for each available processor, processor 0 being the first one. Global average activities among all processors are also reported. The mpstat command can be used both on SMP and UP machinesbut in the latter, only global average activities will...
(the global as well as the per-policy ones) are then reset to their default values, possibly depending on the target operation mode.]That only is supported in some configurations, though (for example, if theHWP feature is enabled in the processor, the operation mode of the driver cannot ...
Processor affinity, or CPU pinning, enables the binding and unbinding of a process or a thread to a central processing unit (CPU) or a range of CPUs, so that the process or thread will execute only on the designated CPU or CPUs rather than any CPU. This can be viewed as a modificatio...
It is important to note that worst case operating voltage is the LOWEST voltage that the processor is spaced to operate at as in general, the lower the voltage…. the lower the operating frequency. Additionally, note that the highest operating temperature as the hotter the CPU is, the slower...
