cpu

问题 There are many questions similar to this but I haven't found solution there. How can I get CPU temperature in C or C++ on Linux Ubuntu 12.10 without call to sensors ? I can of course just read it from file, however I cannot find where it is stored in 12.10. And is simple reading a text file only possibility or maybe I can query the kernel using system call or signal? Content of my folder /proc/acpi/ is just event wakeup No THEMP0 there or anything like this. sensors application however can

问题 I ran the following Java code on a Linux server: while (true) { int a = 1+2; } It caused one CPU core to reach 100% usage. I'm confused about this, because I learnt that CPUs deal with tasks by time splitting, meaning that the CPU will do one task in one time slot (CPU time range scheduler). If there are 10 time slots, the while true task should have at most use 10% CPU usage, because the other 90% would be assigned to other tasks. So why is it 100%? 回答1: If your CPU usage is not at 100%,

问题 This question already has answers here : Get Memory Usage in Android (6 answers) Closed last month . I want to get the average CPU usage in Android per 100ms or 500ms. I have tried to use top and dumpsys cpuinfo , but neither of them tell me the average usage or the timestamp. So how can I get the average usage? I notice that there is some CPU usage information in /proc/stat , can I calculate average CPU usage using /proc/stat ? 回答1: I've tested the solution by Krypton, and got wrong numbers
