Question about using cores for emulating..

[slax65]

Hi folks,

I was wondering if it's possible to use all four cores I got for emulating, instead of just two ..
wouldn't I get a little speed-up?? Cause I have the Intel i7 930 @ 2,8 GHz and the Nvideo GTX 580,
most games are running in full speed .. I use SpeedFan to look after the temps of my hardware while playing and
I noticed, that the CPU is only 30% in use while playing ..

Search the forums, this has been answered only a million times

can't you answer it a million and one time, just for me.. ?
Cauze I'm really interested ..

multi-threaded PowerPC Emulator written in x86-64 assambly , find a genius to make one.

so that would mean, if I was a genius, inventing an emulator or improving dolphin to use 4 cores, people
with a lower cpu, where games usually would run very slow, would get a better emulation?

Can you explain to me why this is such a big thing to deal with?
As I said I'm gettn really interested in all that ..

By the way, I don't know much about computer hardware, but is it possible to get the power of the two cores,
which are not used while emulation, additional to the two used cores?

If only you could code dolphin....Many coder tried , multi-threading didn't make dolphin run faster but more incompatibility with game
Dolphin can use 3 cores atm (with LLE on thread)
If you want huge speed up :
_Buy aftermarket cooler , aftermarket thermal compound
_Then overclock your i7 930 to 3.6 or 3.8Ghz

The OP should really learn to search the forums or google around. In the time it took to make this thread, Google would have had the answer in seconds. At any rate, there's a multi-threading topic in the Development forum (a long, good disucussion, not the closed one on the first page) that details a lot of why Dolphin is at most going to use 3 major threads.

IIRC, Dolphin had experimentally been tested to use more cores, but there wasn't a boost like one would expect. If you split a program's tasks into smaller parts to run simultaneously, you need to make sure all of those parts are kept in sync, which can cause a lot of programming headaches, and defeat the performance gain you'd like to see. It's not always a matter of throwing more cores at the problem. Also, I think the GC/Wii hardware itself is ill suited for quad-core emulation. The way both systems were designed isn't easily broken down so that you could emulate it with 4 cores. Of course, I'm not a dev, nor an expert on multithreading; this is just info I've picked up here and there.
