I'm afraid the miner will be classified as a virus for a long time, because many viruses will use it.

Ufasofft i was wondering if you could make an build that uses only half of the power that computer has, like if it has 2 CPS to use just 1 or so?
I would like this low build because it will allow you're computer to do other things when you are using the miner whitout any lag or so.

Ufasoft:  can you give out the latest sources, so we can compile under Linux

Latest Linux sources are not ready yet.

You can already do this using CPU AFFINITY if you are using Guiminer as a front end.

I am using guiminer as frontend but it doesn't matter if i select only 1 cpu afinitty, it still uses all the power of the proccesor and is still mining at the same rate like i am mining with all the cpus....

That's why the -t switch was invented. -t 1-X number of threads, which means cores. By default, it uses all. Specify this in the arguments, say -t 1 and it will use one core.

Yes i know, it is mining at half of the speed but it still uses 90% of the cpu power....

After you have specified the number of threads, set(if possible use task manager) the cpu affinity to be at core X or whichever you choose. And that's basically it.

I have already set the affinity from the guiminer.

There's a slight possibility it's not working via guiminer. Do it via Task Manager. Also, how many cores do you have?

Binary for Debian 5.0 "Lenny" (it may work in other Linux distro's).

Only 2 cores.

Then what did you expect? I have a quad core, so if i use one thread that's only 25% of my CPU. For you, it will be 50%. Basically, that is why you have the so called "high cpu usage"

Maybe he expects 50%. That's what I get on my dual-core systems with one thread, and that is what he should be getting based on your post.  The 90% that he is getting is significantly higher than 50%  I hope someone congratulates me on making a pot as useful as yours...

Looks like I was wrong, although not entirely.

On my Core2Duo/Quad systems, I need to use the -t flag.

On my Core i7 systems, I can use the Guiminer CPU affinity to set the number of threads in real time, without the need for a stop/start.

On my Dual Xeon X5500 (i7 platform/LGA1366 Dual), I can watch each of it's 16 threads come to life or die when switched either on or off using Guiminer's affinity checkboxes.....same with my i7 920 8 thread systems.

I have nothing AMD-CPU-based to test......

Just a random thought, but might you be willing to add further SSE optimizations such as SSE3, SSSE3, SSE4.1, SSE4a ect. which can be enabled based upon the detected CPU?  I've seen modest improvements enabling some of these through assembly based on your code and was thinking you might like to try them out and see what happens.  Most notably, the use of non-temporal moves from memory to cache increased the hash rate by about .5 that I recall.  I'm not certain if SSE3 optimizations will be helpful though since they mainly focus on horizontal math, though some of the bit rotations could possibly be translated to addition problems to take place simultaneously if the rotations are small.  Say, for example, that you have a rotation of 3 to take place for 4 numbers; by using horizontal math, you can take those 4 instructions and shrink it down to 3.  Now, I don't know the cost of doing so, but the compiler will determine that.

Just a thought.
