cpu

I'm trying to use Java to get the percentage of CPU used by the currently running Java Virtual Machine. My research has pointed me to using the com.sun.management.OperatingSystemMXBean class. Following examples online, I've written the following: import java.lang.management.ManagementFactory; import com.sun.management.OperatingSystemMXBean; public class TestClass { public static void main (String[] args) { OperatingSystemMXBean bean = (com.sun.management.OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean(); System.out.println(bean.getProcessCpuLoad()); System.out.println(bean

I am developing a C# program, and i have one function that consumes too much CPU. I would like to know a way to control this by code (not with any external application) and restrict the percentage of CPU usage. For example, if it uses 90% of the CPU usage, to make my app consume only a 20%, even if it becomes slower. It must be done automatically and from within the app. If you provide a class, it would be fantastic. I don't know if you can do that, but you can change the thread priority of the executing thread via the Priority property. You would set that by: Thread.CurrentThread.Priority =

My Xcode started to behave very heavily from yesterday when working on medium size project (around 200 source files). Project compiles correctly and runs in both simulator and device. I do not use any 3rd party libraries, except few widely used includes (like JSON or facebook ios sdk). It constantly uses CPU(s) at full speed, even if it is in idle state (no indexing, no compiling, no editing). The usage of RAM is relatively normal (300-50MB). My machine uses: Core 2 Duo 3.04Ghz CPU, 8GB of RAM and Vertex OCZ 3 SSD drive. I have tried every suggested solution found at stackoverflow: Cleaned

What do you think the future of GPU as a CPU initiatives like CUDA are? Do you think they are going to become mainstream and be the next adopted fad in the industry? Apple is building a new framework for using the GPU to do CPU tasks and there has been alot of success in the Nvidias CUDA project in the sciences. Would you suggest that a student commit time into this field? Mo. First of all I don't think this questions really belongs on SO. In my opinion the GPU is a very interesting alternative whenever you do vector-based float mathematics. However this translates to: It will not become

Sensor Type TYPE_TEMPERATURE has been deprecated [since Android 2.3] probably which was giving info about CPU temperature. Now we have Sensor Type TYPE_AMBIENT_TEMPERATURE which will provide us room temperature (none of my use, & btw not all devices&/Android versions support it) I checked few apps which measures CPU temperature. Probably they're reading system files. I tried locating, in some devices I'm able to locate it inside following path: sys/devices/virtual/thermal/thermal_zone0/temp The structure bit varies from vendor to vendor & also the unit of measurement. fine! But in many devices

The attached simple Java code should load all available cpu core when starting it with the right parameters. So for instance, you start it with java VMTest 8 int 0 and it will start 8 threads that do nothing else than looping and adding 2 to an integer. Something that runs in registers and not even allocates new memory. The problem we are facing now is, that we do not get a 24 core machine loaded (AMD 2 sockets with 12 cores each), when running this simple program (with 24 threads of course). Similar things happen with 2 programs each 12 threads or smaller machines. So our suspicion is that

I need to control C-State configuration. Specifically, I'd probably like to execute the following asm code: __asm { rdmsr and eax, 0x00 or eax, 0x01 wrmsr } Currently, I got this exception on rdmsr line: Unhandled exception at 0x00e3139e in MessWithCStates.exe: 0xC0000096: Privileged instruction. How can I (permanently) elevate priviliges of my app so it could execute the code above? I use VS 2010. NOTE: It is possible without writing a kernel-mode driver. See R/W Everything . Chances are, you are running this code on an x86 processor within Ring 3. You do not have the privileges to execute

How can I get in c# the CPU frequency (example : 2Ghz) ? It's simple but I don't find it in the environnement variables. Thanks :) var searcher = new ManagementObjectSearcher( "select MaxClockSpeed from Win32_Processor"); foreach (var item in searcher.Get()) { var clockSpeed = (uint)item["MaxClockSpeed"]; } if you wish to get other fields look at class Win32_processor Try this code using System.Management; uint currentsp , Maxsp; public void CPUSpeed() { using(ManagementObject Mo = new ManagementObject("Win32_Processor.DeviceID='CPU0'")) { currentsp = (uint)(Mo["CurrentClockSpeed"]); Maxsp =
