It depends on your software, availability of parallel licenses, memory configuration, model setup etc. Start reading these:

Although I would subscribe to this conclusion, I dont like the fact that these results were obtained on two completely different systems (for example linux vs windows)

Have you seen a significant difference between similar systems running different operating systems? When I went to the trouble of measuring that, I found no difference between Linux and Windows, although different compilers did make a significant difference.

I was not saying that the huge difference observed in the "benchmark" came from the operating system.
If I had something to say in the last purchase of a workstation for our lab it would have been an opteron-based system. It is just not a good practice to run such a comparison with different setups. |
