使用openmp使每个线程的静态变量私有 [英] making a variable static private to each thread using openmp

问题描述

我需要使每个线程的t静态，我该怎么做?我试过了，但是t不是每个线程的静态私有变量.

#pragma omp Parallel
{
    traceRays();
}
...
...
void traceRays()
{
    static float t = 1;
}

解决方案

如果未在并行区域中声明静态变量，则每次尝试在并行区域中定义时，请使用:#omp parallel private(t)

I need to make t static to each thread, how can I do that? I tried this but t is not static private to each thread.

#pragma omp Parallel
{
    traceRays();
}
...
...
void traceRays()
{
    static float t = 1;
}

解决方案

if the static variable is not declared in the parallel region, then everytime you attempt to define in the parallel region use: #omp parallel private(t)
