cpu

问题 If I use async functions, or functions with callbacks like the native fs module, http etc, will they run by default across all cpu cores? Or the entire thing will just use 1 core? 回答1: Some asynchronous operations in node.js (such as file I/O in the fs module) will use additional threads within the node.js process via a thread pool in libuv. It would depend upon the size of your thread pool and what types of operations and upon your host OS for how many additional CPUs will be engaged. It

问题 I am getting the "In line 1, expression expected" error and I am not sure why. I am using the CPU Emulator from nand2tetris. I tried changing line 1 to 5, but it did not solve the problem. I just do not get what is the problem in the first place. @j D=5; @i; M=1; @5 @i D=M D=D-A; @END D;JGT @j @1 M=M-A @i @1 M=M+A @LOOP 0;JMP What I am trying to recreate is this loop: J=5 for(i=1; i<5; i++) { j-- } 回答1: There are several issues that pop out at first glance. First, D=5 is not a valid Hack

问题 I have a cluster running Kubernetes v1.6.7. The VMs are : Distributor ID: Debian Description: Debian GNU/Linux 8.7 (jessie) Release: 8.7 Codename: jessie Kernel : 3.16.0-4-amd64 We have set cpu limits in deployments, however pods comsume cpu over this limit if they need to. Is there something am I missing ? Like a parameter in kubelet to enable this limit ? I haven't found anything about this problem. For example, if I create the following deployment : apiVersion: extensions/v1beta1 kind:

问题 I have a model that needs to be optimized to CPU. Currently the model takes a 1024 x 1024 bytes data. images = img[y:y+1024,x:x+1024,:] As per this document, they want to change the default tensorflow data format from NHCW to NCHW format. How can I transform from NHWC to NCHW format? https://software.intel.com/en-us/articles/tensorflow-optimizations-on-modern-intel-architecture 回答1: As per this document, they want to change the default tensorflow data format from NHCW to NCHW format.

问题 If we consider an hierarchical single level write back cache with write allocate policy , then the formula for average access time during write operation is given by :- Twrite = (H)(Tc) + (1-H)(Tc + Tm + (x*Tm)). Where, H= hit ratio of cache. Tc=access time of cache. Tm= access time of memory. x= fraction of cache blocks which are dirty. The above formula is given in this site https://gateoverflow.in/14480/formula-write-back-write-through-access-time-parallel-serial?show=14502#a14502 However,

问题 I have a large project with lots of classes. It takes 40% CPU when it is running. What is the best way to find out what operations and functions are responsible for the load? I am using Flash Builder 4.5 AS3 Project. Built-in profiler doesn't help me much. Thanks 回答1: You can try SWFWire Debugger. Check the box that says Show method entry . If you also check Show method exit , it will tell you how long each function took to execute. The object graph might also help if you are creating and
