I am learning about OpenMP concurrency, and tried my hand at some 开发者_如何学编程existing code I have. In this code, I tried to make all the for loops parallel. However, this seems to make the progr
This is a follow up to Why is my OpenMP implementation slower than a single threaded implementation? .
I have an R package which is easily sped up by using OpenMP. If your compiler supports it then you get the win, if it doesn\'t then the pragmas are ignored and you get one core.
I have a c++ routine standalone_c.cpp and a wrapper for this in fortran standalone_f.f90 which wraps standalone_c.cpp. standalone_c.cpp is multithreaded using a openmp pragma. I am able to compile bot
I would like to know exactly what is going on with omp parallel for开发者_如何学JAVA and other similiar constructs. How do I find how these are implemented? A short summary of someone who knows about
I have three nested loops 开发者_Python百科but only the innermost is parallelizable. The outer and middle loop stop conditions depend on the calculations done by the innermost loop and therefore I can
I’ve just noticed that the following code doesn’t compile in OpenMP (under GCC 4.5.1): struct job {
I h开发者_如何学Pythonave a C++ number crunching program. The structure is: a) data input, data preparation
Executive summary: How can one specify in his code that OpenMP should only use threads for the REAL cores, i.e. not count the hyper-threading ones?
Greetings all, In my QT application, I use OpenMP to parallelize loops.In the loop , I want to update progressbar values of the current QMainWindow.
