fluent并行

关于fluent并行计算，现在我正用fluent进行并行计算，有30、70、100万网格三个算例，我有8台双核的计算机可以用。感觉并行的速度不理想，请问这得高手有什么好的方法吗？？谢谢|lw,$

This is a very general question both for hardware and software.
Regular clusters loosely connected via Gbit network with high latency will not gain you too much
speed up. The better choice is using low latency high bandwidth network such as infiniband or myrinet.
What network are you using to cluster you 8 dual core machine?
On software side, basically you need to understand how Fluent implement their parallel strategy and read their technical documents about this topic will help you.
If the problem has a large serial portion(such as dealing with I/O, intialization ...), reduce them as much as possible. Anyway, you won';t get too much speedup if your application has only 60% parallel region.
good luck
