#pragma omp atomic 使用#pragma omp reduction(+:sum)或#pragma omp critical 但是我认为#pragma omp reduction会更好,因为你可以将sum+=Var;添加到里面。 像这样做: x = (i + .5)*step; double z = 4.0/(1.+ x*x); #pragma omp reduction(+:sum) sum += z; - Aizen 这很有帮助。比我之...

The crystals were refined using the platform ModRefiner freely available at [53] This platform was assessed to generate algorithms that were used to build and enhance protein structures utilizing the traces of Cα established by two-step atomic-level of energy minimization. Next, molecular docking ...
