Ubuntu 12.10 64bit: To compile or not?
I have put together a new computer with intel core i7 3930K, 32GB Ram, 1TB hdd, nvidia GTX 570. I'll install Ubuntu 12.10 and I would like to install OpenFoam for everything CFD, my questions are:
1. Are there any gains in compiling OpenFoam from source vs. installing from the binary file?
2. If compiling from source is the way to go, which compiler should I go for, will ICC be the obvious choice? Or does the latest version of GCC have the edge?
3. Do I need code vectorization, or use of pragmas to achieve better performance? I'm no expert on these terms but I have seen them mentioned in threads discussing GCC vs ICC.
In quick reply:
Thanks a lot Bruno, sorry if I posted in the wrong forum. I'll keep coming to this thread and report my findings & further questions.
