C++ PPL - 开始合并
原标题:C++ PPL - initialize a combinable

请允许我说,在扩大范围时,我有一些变量,即每个变量在平行地接近——就应当能够进入。 我的想法是合用的,每读一个版本的我变量。 然而,我不理解如何开始我合并的一件事:

例如,我想使用QString公式的复印件。 我为每一条read子的涂料创造了一个共同的地位:

 combinable<QString> formulaRx;

如果我写了:

parallel_for(0,p,[&formulaRx, formula](int i)
{
         formulaRx.local() = formula;

         // do things

 });

? 这是否解决这个问题,或者是否仍然可以同时进入。

 formulaRx.local() = formula;

如何处理这一问题?

请告诉我,如果我没有清楚的话,请告诉我:

感谢和尊敬 S.

最佳回答

you do not need to assign formulaRx.local(). This is a getter for the local copy of the combinable object.

parallel_for(0,p,(int i)
{
     QString f = formulaRx.local();

     // do things with f which is the local copy of formulaRx

});
