Jep, I know, buy one, get two or more CPUs. :) > Of course, individual programs (particularily monothreaded ones) are not > accelerated on a bicore processor. Ok, that was obvious for me. > In practice, for common use, you just need to install an SMP kernel (but > recent ones ie 2.6.21 are always SMP!) et voilà. That was not really clear. :) But it is simple, nice nice. > Of course, don't expect any sequential number crunching program to speed > up. You'll need to parallelize it. I do not wan't to start in numbercrunching with the new workstation. > What precisely do you intend to do with your new bi-core workstation? I did not get the workstation for a special task. I only get a new one, because my computer is really old and I want to have a look at 64bit archetectures. :) The newer processors are only multiple Core CPUs and what I do not want is to let some performance unused, because of using a SMP-System only as a single processor system. Therefore I wanted to know, what I have to do for using SMP. I did not exactly know, that threading (most of the applications are threading) and turning on SMP in the kernel is enough. But that question is answered. Many thanks. :) Best Regards. Jan
