About default(none) and shared() directives

Hello: First of all I should say that although I used OpenMP for a long time I stopped programming for a while and now I've returned, so I'm a bit rusty. This is the reason of my question. Some time ago this piece of code was correct: int function(const int* list,const int N) { int i=0,sum=0 #pragma...

Call for cancellation structure simple example

Hello: First of all, thank you all people involved in the examples document. It's a great work! I'm trying to learn about the new 'cancel' directive and I find the examples a bit complicated.

Parallelize a sum over certain parts of an array

Hello: I need (well, the actual job is a bit more elaborated, but I simplify as example) to sum certain elements of an array in certain number of groups. I think it could be parallelized via OpenMP, but I don't know how to deal with the problem. First, I paste the example code: #include<stdio.h> #if...

The book and OpenMP 4.0

Hello: The future OpenMP 4.0 includes important features in the standard as the "cancel" instruction, the SIMD features and, above all (IMHO), the support for accelerators.
