what is difference of a multi-core and the multi-processor system?

1. are JamesMolly tuts work for multi-core cpu?
2. hlt,cli and sti works for all cores or only for one
3. gdt,idt and other descriptors must be programmed for all cores?
4. programming way are difference with single core system?

sorry for my bad english

The difference is that one system has multiple cores (one processor can have one or more cores), while the other has multiple processors. However, the two terms are sometimes used interchangeably.

1. If he handles multiple cores, he will say so in his tutorial. You haven't read it, but you ask questions about it.
2. Have you tried looking up these instructions in the manuals?
3. Have you tried looking up these descriptors in the manuals?
4. MP systems are a totally different architecture, despite the cores perhaps being binary compatible (as is the case for x86 CPUs).

I can't help but notice that all these questions can easily be answered by RTFM'ing; you're asking us because you have no intention of doing that yourself. This might be useful in the future---you have violated many rules that one should obey on a technical forum. However, I don't expect you to read it since you didn't bother skimming through the manuals for your questions.

That's the point, he doesn't. Hence, the answer is obvious.

Correct, they aren't answers. You need to earn answers by obeying to the forum's rules---that's how our community (and all others) works. You are not allowed to ask questions before doing your own research; I have even hinted as to where to look for the relevant information and you are still complaining. That's another minus.

Hypocrite?

Multiprocessor systems have just that: multiple processors. Now think about what you asked. If processor 1 affects processor 2 it must be documented somewhere.

Thats where you're wrong. He is telling you to find the answer yourself. It can be done very easily. You will need to know how to find answers like these yourself, because there is so much information you need to know for osdev that you cannot ask everything on these forums. He is helping you. If you're too lazy or incompetent to look up the answers yourself, we cannot help you.
