cpu-usage

问题 I'm looking for a way to limit the CPU usage by any application on Windows 7 to 50%. I've tried searching the Internet for a way to do this, and it looks like this is an easy thing to do on Linux and Mac OS X (one command in the terminal) but I'm not sure how to do it on Windows 7. Any help would be much appreciated. Thanks! Rohan 回答1: You can use BES. It throttles CPU-hungry applications when asked. You can limit 3 programs maximum. I use this to run multiple online game clients and it works

问题 My python process at certain point in automated scripts starts chewing CPU on Linux based System (Ubuntu). I’m trying to debug this issue in GDB. I'm fairly new to GDB. Are there any GDB commands to give information on which thread is using most of the cpu. Looking at the thread stack doesn't really give that away. On windows windbg world the command '!runaway' did give the info on time consumed by each thread in a process. Do we've an equivalent command here ? Any other suggestions to debug

问题 When I check azure monitoring tool, CPU usages are shown in CPU time min: 4.69s max: 2008.08 s avg : 207.63 s I am familiar with CPU% which makes sense as in application requiring cpu cycles. how does the above time correspond to percentage? What would be the max in seconds which corresponds to 70 or 100% cpu usage? note : cpu is 4 cores On a different instance, I noticed in a 60 second window min: 0 max : 133.83 avg : 19.61 Based on below answers (see Nachiket's explanation in comments as

问题 I am creating a simple script that outputs the current user logged in, CPU usage for the current system and the available memory? I have managed to get the current user/s logged on but is it possible to get the cpu usage and memory as well? This is my code so far. @echo off for /f "tokens=3 delims=\" %%i in ("%USERPROFILE%") do (set USER=%%i) 2>&1 echo "Logged On User: %USER%" echo. pause To get the cpu usage i have tried this command but it doesn't seem to be working. for /f "skip=1" %p in (

问题 I've written a C++ library that does some seriously heavy CPU work (all of it math and calculations) and if left to its own devices, will easily consume 100% of all available CPU resources (it's also multithreaded to the number of available logical cores on the machine). As such, I have a callback inside the main calculation loop that software using the library is supposed to call: while(true) { //do math here callback(percent_complete); } In the callback, the client calls Sleep(x) to slow

问题 Is there any way in C++ to calculate how long does it take to run a given program or routine in CPU time ? I work with Visual Studio 2008 running on Windows 7. 回答1: If you want to know the total amount of CPU time used by a process, neither clock nor rdtsc (either directly or via a compiler intrinsic) is really the best choice, at least IMO. If you need the code to be portable, about the best you can do is use clock , test with the system as quiescent as possible, and hope for the best (but

问题 On Ice Cream Sandwich, an option in the Developer Options is "Show CPU Usage", which adds an overlay on the screen (see screenshot below). My question is, how do I read the data ? I guessed that the package names are the process currently actives, but what does the red and green bars behind mean ? Also what are the 3 numbers on top of the packages ? 回答1: This should be the Unix load average. Wikipedia has a nice article about this. The numbers show the average load of the CPU in different

问题 I am looking at the Activty Monitor for SQL Server 2005 and we have some processes that are taking up large amounts of the CPU. When I look at what is trying to be run I get: set transaction isolation level read committed This code is not coming from any of our applications. What is causing it? What should be done? 回答1: Look at sys.dm_exec_sessions and sys.dm_exec_connections for the session ids that take up CPU. You'll find the application name, host name and process id of the client. 回答2:

问题 I am currently working on a project in Android. I want to get the total cpu usage of each and every process. So i am using the contents of "/proc/pid/stat". I referred this answer to get the stats. Now i got all the utime, stime etc., The problem is with the value of "Hertz". The answer says that it is the number of clock ticks per second. I don't get the exact meaning of clock tick even after browsing a lot. What is a clock tick and is it the frequency of the processor? And the answer says
