cpu-speed

问题 This question already has answers here : Getting processor information in Python (10 answers) Closed 5 years ago . I'm trying to find out where this value is stored in both windows and osx , in order to do some calculations to make a better task distribution. Core speed in Hz Thanks in advance. Using the platform.process() command only returns the name not the speed I only managed to get it trough this: import subprocess info=subprocess.check_output(["wmic","cpu","get", "name"]) print info

Are they just figured out using the same mechanism as a linear search or is the range narrowed down somehow, similar to a binary search. 回答1: The implementation of a function such as the natural logarithm in any

问题 I'm trying to find out if there is anyway to get an idea of the CPU frequency of the system my C code is running on. To clarify, I'm looking for an abstract solution, (one that will not be tied to a specific architecture or OS) which can give me an idea of the operating frequency of the computer that my code is executing on. I don't need to be exact, but I'd like to be in the ball park (ie. I have a 2.2GHz processor, I'd like to be able to tell in my program that I'm within a few hundred MHz

问题 I'm trying to get cpu speed. This is what I've done so far $cpu = [string](get-wmiobject Win32_Processor | select name) $($cpu.split("@")[-1]).trim() and my output is 2.40GHz} How can I remove "}" from my output without having to play with string functions? Is there a better way to achieve my goal? Thanks in advance 回答1: PS > $p = Get-WmiObject Win32_Processor | Select-Object -ExpandProperty Name PS > $p -replace '^.+@\s' 2.40GHz 回答2: You know what ... I'am Unhappy ! Powershell gives objects

问题 I have been reading the cpuinfo file on my Samsung Galaxy (sgh-i897) to retrive the bogoMIPS value. And just now learning how to interpret such information. Initially I did this under the main activity in a loading thread, and ALWAYS got a value of 997.59. I then moved the file reading method into a Service since I didn't need it in the UI until much later anyways. Once I did this, the value I read became quite different, and seems to change for each application start, always much slower,

问题 I would like to do some microbenchmarks, and try to do them right. Unfortunately dynamic frequency scaling makes benchmarking highly unreliable. Is there a way to programmatically (C++, Windows) find out if dynamic frequency scaling is enabled? If, can this be disabled in a program? Ive tried to just use a warmup phase that uses 100% CPU for a second before the actual benchmark takes place, but this turned out to be not reliable either. UPDATE : Even when I disable SpeedStep in the BIOS, cpu

问题 I hear everyone talking about how multi-threading can improve performance. I don't believe this, unless there is something I'm missing. If I have an array of 100 elements and traversing it takes 6 seconds. When I divide the work between two threads, the processor would have to go through the same amount of work and therefore time, except that they are working simultaneously but at half the speed. Shouldn't multi threading make it even slower? Since you need additional instructions for
