这样我们的第一个MPI程序就成功了,而且它在服务器上也是可以直接跑的。 Step 4:速度对比 现在我们再进行一个简单的速度对比看看,首先我们在Euler_Forward这个子程序里添加一个system_clock的计时,然后把它输出出来: subroutine Euler_Forward use com integer t1,t2 CFL = 0.2 dt = CFL*hx t = 0 call system...

I would also suggest checking out theHelp/Support section of the Open MPI webpage as they would be the most qualified to answer Open MPI questions. Also, just as a quick note: the link you provide requires a login. Could you summarize or copy/paste the content from ...

并行编程:是的,MPI和OpenMP都可以很好地与C和Fortran一起工作。然而,如果你想真正控制你的线程,也就是说,如果你有一个完全动态的共享内存计算,你就会被Fortran所冷落。在C语言中,您有标准线程,虽然不温暖和模糊,但仍将帮助您度过难关。一般来说,大多数依赖于访问操...
