cpu

问题 I need to obtain CPU information on Android. After some research, I found out that reading '/proc/cpuinfo' is one way to do it. My question is - does the device need to be rooted to read '/proc/cpuinfo' on an Android device? Is '/proc/cpuinfo' even guaranteed to exist on all Android devices. 回答1: You do not need root privileges to read /proc/cpuinfo 来源： https://stackoverflow.com/questions/8519867/does-the-device-need-to-be-rooted-to-read-proc-cpuinfo-on-an-android-device

问题 A model is trained with GPU and result is saved by checkpoint file. The saved checkpoint file can be run by cpu-tensorflow? If not, can convert the saved checkpoint file so as to run model in cpu-tensorflow? 回答1: Yes! It normally can! The exception is with tf.device('gpu:0') statements. If you do not have them in your code you are good to go! Good luck! 来源： https://stackoverflow.com/questions/42951543/tensorflow-model-trainedcheckpoint-files-on-gpu-can-be-converted-to-cpu-runni

问题 I am trying to get the % of total CPU usage to a label1.Caption I've searched and found these: didn't work - http://www.vbforums.com/showthread.php?345723-DELPHI-Get-CPU-Usage not what I need - http://delphi.cjcsoft.net/viewthread.php?tid=42837 also found bunch of solutions regarding calculating the Usage per process but that is not what i am looking for , i just want the total CPU usage like this widget : this is what i am working on : I believe there is a simple way like when we get RAM

问题 I need the number of operations per cycle that an ARM processor can execute, in particular those of Cortex-A7, Cortex-A9 and Cortex-A15. I can't find anything online! Thank you EDIT: I need it for calculating the theoretical peak performance. 回答1: I have not looked into integers yet but for single and double floating operations per cycle this is what I have come up with so far (from flops-per-cycle-for-sandy-bridge-and-haswell-sse2-avx-avx2, peak-flops-per-cycle-for-arm11-and-cortex-a7-cores

问题 I want to convert the String (result) of the following function into an Integer value and divide it by 1000 (khz -> mhz) private String ReadCPUMhz() { ProcessBuilder cmd; String result=""; try{ String[] args = {"/system/bin/cat", "/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq"}; cmd = new ProcessBuilder(args); Process process = cmd.start(); InputStream in = process.getInputStream(); byte[] re = new byte[1024]; while(in.read(re) != -1) { result = result + new String(re); } in.close();

问题 I've forked the system messaging app and it is consuming the majority of my CPU, and others have reported the same. I cannot for the life of me determine why. I figured the drainage could be possibly two things (because of how much it is draining): a wakelock that has not been released, or a service doing continuous computation. Here's what I have tried: adb shell dumpsys power This shows Wake Locks: size=0 so I am assuming it is not a wakelock issue (the app uses wakelocks, of course, but I

问题 I have basic binary math question. For example; reg [31:0] a = 32'hFFFF_FFFF; reg [31:0] b = 32'hFFFF_FFFF; reg [31:0] c = 0; I know c = a - b will result in zero and overflow flag will not be set. My understanding is that ALU uses 2's complement of subtrahend (right side of operator) and adds it to minuend (left side of operator). So 2s complement for value stored in reg b is 32'h1. Now, if I add this to reg a, I will get 32 zeros and a 1, which is overflow. Then why is not overflow flag set

问题 I had the following question: BitmapData lock and unlock not working on android Now, encountering that issue, reading about render mode, I'm very confused how a script that simple fails in GPU mode,but is very fast on CPU mode. So the question is, how GPU mode works and how CPU mode works for adobe air? And why on GPU most of the stuff works better, but not that script Note: Base bitmap size should be bigger than 1400x1400 回答1: There are some limitations on GPU render mode. Adobe recommends

问题 I have a web app that will definitely be a low-traffic app (less than a few dozen hits per day), but when it does get a "hit" (the user actually has to kick off an action), it wakes up and does some heavy-duty number crunching (very CPU-intensiive) for several hours per request . As such, once live, I could foresee the server's CPUs going full bore throughout the day, even though the site itself might only receive ~15 visitors and even less number-crunching requests. I'm trying to determine
