utilising multicoreprocessor support in linux 2287

Aragorn

Perhaps I shall have a look at it, but I dont think this processor supports hyperhtreading. I think I read somewhere that they disabled it for this processor type because you didnt gain much by it.

Thanks for the tip, I also found that adding the P column show which processor the process is running on. (and some other columns can be added to get thread information.)

I have to use 2.6 because the machine wont run on anything pre 2.6.7

Thats what everybody says, but what I was looking for was hard facts, a top-ps output showing me that this was the case on my machine, fortunately I found parts of it.

Thanks for the tip, I think for most userapps multiprocessing is fine, but for some I might consider recompiling with threading support.

Only if we use the same search expression ;)

Ive tried searching for things like "linux smp administration", ".. multicore.." "...multiprocessing..." and so forth but all I get are a couple of year old articles saying how wonderful linux is now that it supports smp systems and so forth. I cant seem to find anything about how to use sysadm tools to get an overview of or controlling the smp operations of the linux kernel, f.ex what tools can be used for such status info, are there any special tools, how to get smp-threading information fromproc etc.

Any hints?
