cpu

问题 I'v searched about this but i don't seem to get fair answer. lets say i wan't to create a vm that has a vCPU, and that vCPU must have 10 cores but i only have 2 computers with 5 cores of physical CPU for each. is it possible to create one vCPU by relaying on these two physical CPUs to perform like regular one physical CPU? Update 1: lets say i'm using virtualBox, and the term vCPU is referring to virtual cpu, and it's a well known term. Update 2: i'm asking this because i'm doing a little

问题 I'm reading about scheduling, but I can't figure out how a scheduler regains control after it invokes code in the user space. E.g. the scheduler passes the control to some app in the user space which does some infinite loop and no other hardware interrupt occurs on an one core chip. All documents talk about the scheduler regaining control and preemptivly interrupting the user process, but how does that work if the control is never passed back to the OS? Question: Does the scheduler register

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . any one can tell me why Max work items for my gpu less than cpu and compute unit ??? is that mean performance for cpu is better than gpu cpu : intel core i7 2.2GH gpu : amd radeon hd 6700M Number of platforms: 2 Platform Profile: FULL_PROFILE Platform Version: OpenCL 1.2 AMD-APP (1084.2) Platform Name: AMD

问题 Can anyone confirm that for example Intel I3 CPU has 2 physical cores and 4 logical cores, so if I set Process afinity to Core #0 so that means I set on first physical cores 1 logical core, but if I set on Core #1 so it means I set on first physical core 1 HyperThreading core, but how about AMD CPU since they got somekind of "modules" atleast what I read on internet, how to work with amd cpus? And does intel ALWAYS has this come physical core contains 1 logical and 1 HT core? How about AMD

问题 I am trying to make a CPU clock speed tracker, but I need some help on the code. setlocal enableextensions enabledelayedexpansion :a for /f %%a in ('copy /Z "%~dpf0" nul') do set "ASCII_13=%%a" set /p "=!ASCII_13!" <NUL wmic cpu get CurrentClockSpeed goto a I'm interested in getting something like this: CurrentClockSpeed 2401 not this (the code I'm trying to use outputs this): CurrentClockSpeed 2401 CurrentClockSpeed 2401 CurrentClockSpeed 2401 CurrentClockSpeed 2401 Can you please help me?

问题 This is a quasi-coding question, yes, but specifically I'm using Xna if that helps... I have a game. The AI and game-rules logic is so efficient that I have a crap ton of CPU cycles available. My question is: can I make my rendering code more complex so it looks better and uses those free CPU cycles? Or is the rendering loop only so complex on the CPU side for any quality of rendering -- and therefore any graphics quality or frame-rate boost would have to come from the GPU? Thanks for any

问题 I have created the following view in Ganglia, showing cpu_user stats: Can someone tell me what Sintr means? I was not able to find any information on Google or stackexchange websites. Interestingly, I have two servers with identical hardware that I'm monitoring, but only one of them has the Sintr entry (which caught my eye). 回答1: Okay, I found an answer hidden in some Ganglia dev mailing list... From this post: I also added two specific metrics to Linux. cpu_intr and cpu_sintr count the

问题 The current task, iterating over massive dictionaries, is giving me a headache. I cannot pinpoint the exact source of high CPU usage here so I hope some of the C# gurus here can give me some hints and tips. The setup is 10 preallocated Guid-byte[] dictionaries, each holding one million entries. The process is iterating over all of them, each dictionary has it's own thread. Simply iterating over all of them and passing byte[] reference to iteration delegate, yielding random result takes under

问题 This question is a follow-up question on Can the C compiler optimizer violate short-circuiting and reorder memory accesses for operands in a logical-AND expression?. Consider the following code. if (*p && *q) { /* do something */ } Now as per the discussion at Can the C compiler optimizer violate short-circuiting and reorder memory accesses for operands in a logical-AND expression? (especially David Schwartz comment and answer) it is possible for the optimizer of a standard-conformant C

问题 First of all if this has been asked before I'm sorry for the duplicate, but I couldn't find the answer to my question anywhere. So, I am pretty new to Python, and I am currently working on a wrapper for a web application. This wrapper starts a subprocess using Popen and then sends information about that subprocess to the web application. Everything is working great so far. Now the only question I have is; Is it possible to get resource usage of a subprocess ( RAM and CPU )? If so, how would I
