Multi-Core code
I want to know how I can get the most from my code, and as speeds per core stay the same, I am looking toward using multiple cores. Most GOOGLE searches come up with news articles talking about multiple cores, and multi-threading C. None of the two useful pages explained the functions at all. I speak C fluently. Please help me with this,

Standard C/C++ knows nothing about multithreading, so to get the best performance in your code you need to use OS specific functions or generic theading libraries like pthreads to make your code multithreaded.
It would help to know what OS you are using in order to narrow down the function calls to a more specific set.

Some links seems very interesting.
Have you already studied Intel webinars on the issue? Intel is pushing very hard the multi-core programming and has a lot of info on it.

except for the problem of too many layers of indirection.

cpjust, do you know how to use the phtreads. I saw some use, but a useless explanation. Mac OS X 10.3 Panther. Could I make the phthreads portable to XP, later Mac OS X, and Vista? I know how to use the #if etc. directives. If you could point me to a site, thanks.

Yes, POSIX Threads (pthreads) for Win32.
Define "useful" then?I saw some use, but a useless explanation.
It tells you how to use them. Function prototypes, definitions, or even explanations.
No offense, but you didn't look very hard if you didn't find anything useful. A simple search on google for pthread and there are a bunch of links that give explanations.
Also, use the link that vart gave and there is a pretty good run through on yolinux.
