cpu

问题 How do I get the CPU usage for each process that is currently running on the local system or server using PHP. How can I use the Command Prompt command tasklist from within PHP and fetch process names and memory information. Here is the example : Name of Processor Memory usage Edit plus 6.1 MB Google Chrome 20 MB Command Prompt 5 MB Tomcat 2.1 MB 回答1: Seeing as you've changed the specification for the answer and I don't wish to remove or butcher my other answer which may be an acceptable

问题 We are having trouble controlling a long running process that uses WCF to send start/stop commands. The problem seems to be that WCF does not respond to the requests when the CPU load is high. Unfortunately, high CPU on as many cores as possible is necessary for the application in question as it needs to perform a large number of numeric calculations. Could the problem be related to the use of the thread pool to dispatch requests in WCF? This (somewhat dated) link suggests that it could: "we

问题 We've just bought a 32-core Opteron machine, and the speedups we get are a little disappointing: beyond about 24 threads we see no speedup at all (actually gets slower overall) and after about 6 threads it becomes significantly sub-linear. Our application is very thread-friendly: our job breaks down into about 170,000 little tasks which can each be executed separately, each taking 5-10 seconds. They all read from the same memory-mapped file of size about 4Gb. They make occasional writes to it

问题 Basically i want to read the cpu temperature in python. Please explain in layman's terms as i have never done this on windows before nor have i had to work with wmi. This is what I have at the moment: import wmi w = wmi.WMI(namespace="root\wmi") temperature_info = w.MSAcpi_ThermalZoneTemperature()[0] print temperature_info.CurrentTemperature (i got this code from this thread: Accessing CPU temperature in python) however, on running the script, i get this error: Traceback (most recent call

问题 So, one of the porpuses of docker is to easily deploy an environment to test software right? Can anybody tell me how to compile a Tensorflow binary to use: SSE4.1, SSE4.2 on a docker file?. Can anybody point me to a docker file that does that? if it is possible at all? In summary, two questions: Is it possible to have a docker file that compiles a Tensorflow binary to use: SSE4.1, SSE4.2 (and GPU, I have only found one or the other) Can you tell me where I can found a docker file that does

问题 I am using LINQ to SQL and seeing my CPU Usage sky rocketting. See below screenshot. I have three questions What can I do to reduce this CPU Usage. I have done profiling and basically removed everything. Will making every LINQ to SQL statement into a compiled query help? I also find that even with compiled queries simple statements like ByID() can take 3 milliseconds on a server with 3.25GB RAM 3.17GHz - this will just become slower on a less powerful computer. Or will the compiled query get

问题 When I run a single-threaded program that i have written on my quad core Intel i can see in the Windows Task Manager that actually all four cores of my CPU are more or less active. One core is more active than the other three, but there is also activity on those. There's no other program (besided the OS kernel of course) running that would be plausible for that activitiy. And when I close my program all activity an all cores drops down to nearly zero. All is left is a little "noise" on the

问题 In terms of instruction set and simplicity of emulation. I would like to implement a virtual CPU and figured why not emulate an existing one, so to be able to compile C code to it. 回答1: Moxie is a great target because it was designed specifically to be an ideal target for GCC. I am the author and would be happy to answer any questions. green at moxielogic dot com 回答2: GCC supports Moxie (originally ggx), a little architecture invented by Anthony Green for experimentation. You, too, can follow

问题 I'm working on a small function, that gives my users a picture of how occupied the CPU is. I'm using cat /proc/loadavg , which returns the well known 3 numbers. My problem is that the CPU doesn't do anything, right now, while I'm developing. Is there a good way to generate some load on the CPU, I was thinking something like makecpudosomething 30 , for a load of 0.3 or similar. Does an application like this exist? Also, are there any way to eat up RAM in a controlled fashion? 回答1: I didn't

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago . now i know this question has been asked quite a few times now but i'm not really wondering how much memory a 32bit processor can address neither theoretically nor practically. just a quick heads up, i come from a civil engineering background so i'm still learning in terms of
