如何编写在网格上运行的软件?

问题描述

我可以访问我大学的网格系统(在具有100多个节点和1000多个CPU的Sun Grid Engine 6.1上运行)

我有一个程序，它基本上是用C ++编写的在某些数据集上运行遗传算法的程序.当前，它在单个线程中执行.


我的问题是..是否需要我自己使用MPI和OpenMP来并行化程序?还是由主机引擎本身完成并行化?


如果必须自己进行并行化，应该创建多少个线程?



在此先感谢

I have access to my university''s grid system (running on Sun Grid Engine 6.1 with 100+ nodes and 1000+ CPUs)

I have a program, which basically runs genetic algorithm on some dataset, written in C++. It currently executes in a single thread.


My question is.. do I need to parallelize the program on my own, perhaps, using MPI and OpenMP? Or is the parallelization done by the host engine itself?


If I have to parallelize on my own, how many threads should I create?



Thanks in advance
