问题 I am new in C#, I am developing the project at C#.net windows application in that I need to read the next schedule time from my schedule file, if there is no schedule for next one hour, my system need not to wake on until next schedule time reach which is defined in schedule file. My system needs to shutdown, and before shutdown it need to set the timer for system wake. How to set the system on time before shutdown my pc. I did this same in Linux system through python script by writing the

问题 Summary: My original question and observations are followed by an updated working OpenGL code for Intel HD Graphics 4000 GPU. Original question: Two cubes are shown on Nvidia NVS 4200m GPU and 1 cube shown on Intel HD Graphics 4000 GPU. Using OpenGL 3.2 forward profile and OpenTK to render 2 simple cubes on screen It shows the first cube centered at (0,0,0) on Intel HD Graphics 4000 with the latest GPU driver 7/2/2014 ver 10.18.0010.3621. It should show 2 cubes. We're using a Vertex Array

问题 What I want to achieve I try to set up a toolchain to compile OpenCL applications for Intel FPGAs. Therefore beneath building the C++ based host application I need to invoke the Intel OpenCL offline compiler for OpenCL kernels. This step should only take place if the cl source file was edited or the resulting binaries are missing. My approach is to add a custom command to invoke the CL compiler and create a custom target that depends on the output generated by this command. The offline Open

问题 I had flashed Intel's pre-built src images on board by replacing u-boot.elf compiled with buildroot(having support for Edison board). But the board is stuck on FSBL(FSBL watchdog is continuously rebooting the board). I tried to flash on board, but on board no listener is present to serve flash operation (usually done by dfu utility in u-boot). So that I am not able to flash pre-built images again. By this present conditions, how can I bring my board up? How can I flash images again? INPUT :

问题 This question already has answers here : How to write or read memory without touching cache (2 answers) Closed 3 years ago . Is there an instruction using which I can move a variable to/from memory and registers without it being stored in cache? I don't want to disable caching entirely by using CD bit, I only want to do this for individual memory accesses. 回答1: movnt stores bypass cache, but movntdqa loads may not do that for normal (write-back) memory regions. The instruction-set reference

问题 Is it required to save/push the any XMM registers to the stack before the assembly function call? Because am observing the crash issue in my code with release mode for 64-bit development(Using AVX2). In debug mode its working fine. I tried with saving the content of the XMM8 register and restoring it at end of function call then its working fine. Any idea or references? 回答1: Yes, on Microsoft Windows you are required to preserve the XMM6-XMM15 registers. See http://msdn.microsoft.com/en-us

问题 I made the observation that my java application is running much faster when executed on an AMD processor in contrast to an Intel CPU. For example my JBoss starts in about 30 seconds on a 3 GHz AMD processor and needs about 60 seconds on a 3 GHz Intel processor with identical disc, RAM and OS? Has anyone else made this observation? Why is this so? 回答1: It depends on the CPU generation as well - clock speed is not everything. If you set up e.g. an Intel Pentium 4 and an AMD Phenom with the same

问题 I know people have asked similar questions like this before, however there is so much conflicting information that I really want to try and clear it up once and for all. I will attempt to do so by clearly distinguishing between instruction set architecture (ISA) and actual hardware implementation. First my attempted clarifications: 1.) Currently there are intel64 and amd64 CPU's out there (among others but these are the focus) 2.) Given that an ISA is the binary representation of 1 or more

问题 I am using intel fortran compiler and intel mkl for a performance check. I am passing some array sections to Fortran 77 interface with calls like call dgemm( transa,transb,sz_s,P,P,& a, Ts_tilde,& sz_s,R_alpha,P,b,tr(:sz_s,:),sz_s) as evident, tr(:sz_s,:) is not contiguous in memory and the Fortran 77 interface is expecting a continuous block and creating a temporary for this. What I was wondering is that will there be a difference if I create my temporary array explicitly in the code for tr

问题 Is there a format of *.gvs files, used by GuideView OpenMP performance analyser? The "guide.gvs" is generated, f.e. by intel's OpenMP'ed programmes with $ export LD_PRELOAD=<path_to_icc_or_redist>/lib/libiompprof5.so $ ./openmp_parallelized_prog $ ls -l guide.gvs 回答1: It s a plain text. Here is an example of such from very short omp programme: $ cat guide.gvs *** KAI statistics library k3301 *** Begin Task 0 Environment variables: OMP_NUM_THREADS : 2 OMP_SCHEDULE : static OMP_DYNAMIC : FALSE
