请问大虾  QT中能嵌入mpi并行库吗？ [复制链接]

如题 哪里有这方面的资料呢？
多谢

You sure can use MPI with Qt because MPI and Qt are two independent C++ libraries. But it may not make a lot of sense:
    1.  parallel computing is not GUI applications related. If you need to parallel any part of your code,
        you need to separate it from your code and make this part stand-alone.
    2. you may need to buy one Qt license for one node. Nobody likes to do this.
However, you can use OpenMP to speed-up your code up if you have multi-core computers.

估计比较悬 :)

顺便问个问题：

MPI中有进程中途挂掉怎么办（怎么支持容错）？

OpenMP和MPI什么关系？

OpenMP is designed for multi-core computers(one computer).
MPI is designed for computers in a network(multiple computers).
You can also use GPU to speed your code up.

if one node falls behind, other computers have to wait. This is overhead for MPI.
Try to do load balancing to reduce overhead.

完全可以的，别听他英文的，我自己就做过
