How to use available memory effectively


I use all cpu processor to run FDTD simulation on the server,but about 40G memory space is still available. What should I do to use it effectively?



I am not so clear about your question.
Do you mean that you have enough memory but the software can not use them and give an err ?
The memory requirement depends on the scale of you simulation,like 2D or 3D ,the mesh accuracy and so on.

Sorry, i did not explain clearly. We have extra memory,i want to use them to speed up my simulation.


Dear @qi.han.1

Simulation speed is controlled by CPU and having more memory than what is required will not be of a help to speed up the process. If your computer does not use all the memory in a simulation, you can’t force the software to do it.

You can read more about this here. The link discusses memory requirement for gaming but with the same analogy, having a memory more than what is needed in a simulation is not of any extra help.

Please let me know if this answered your question.
