PC doesn't work fast
I use ansys cfx 13 for CFD simulations and I have found that a pc is less fast as I expected.
During a simulation (carried out by Ansys CFX Solver) a pc with 8 processors (2 quad core) is as fast as another pc with only 4 processors (1 quad core). The features of the former are: -------------------------------------------------- OS windows 7 ultimate 2 quad core Intel Xeon E5430 32 GB RAM Graphics card NVIDIA quadro nvs 290 Is there an explanation? Can I improve performance of this pc? |
Quick questions:

The pc with fewer processors has the following characteristics:
intel core 2 quad CPU Q6600 @2.40 GHz, RAM 8 GB |
Dumb question but....Are you actually using all 8 processors (are you running parallel or serial)?
|
Your question is much dumber...
It is obvious that i run the simulations in parallel with all 8 processors |
You didn't mention the RAM speed, which might be the main reason for the large difference in performance.
But assuming the speed is the same... here are other possible reasons:
Last but not least, maybe it would be a good idea for you to contact your support for ANSYS, since this could be a specific problem that they know the solution for. Another possibility is to ask in the dedicated thread for CFX: http://www.cfd-online.com/Forums/cfx/ |
