Nonsense! The program is of course running at 100% because it would otherwise be idle, IBM is nice, if you look at the priority in the task manager
at which the Rosetta runs it is set to low, this means any program you normally use such as a wordprocessor will get the cycles it needs and you
don't suffer from the grid program taken up the rest of the CPU power,
this was no other for SETI@Home and no doubt any well behaved distributed computing efforts. Greetings, Harm

Hi all. Just wnated to throw my 2 cents in. The life of your cpu is not determined by usage but by heat. The cooler your cpu stays the longer it will last. This being said, as long as your cpu is adequitly cooled you will not damage it no matter how much it is used. However this can be loud depending on the fan that cooles your cpu.
To give you an idea, does anyone remember a little thin called sasser?
One of the side effects of a variation of sasser made the cpu run at 100%. Other viruses have been known to do this also, but the piont is I personelly never heard of it melting a cpu.

Guys:

I've been running grid software on my computers for over 3 years now. None of them have dropped over dead. My 14 computers include Celeron, PIII, AMD and P4 and P4-HT. I also have one laptop.

My observations over this time: I don't run the software on my laptop very often, because as pointed out, it does heat up the processor and cause the fan to run all the time, which I don't like. But I know some friends who do run laptops all the time. Mine is a cheap off-brand and I don't trust it.

Yes, they heat up the CPU. But as an engineer, I expect my computers to be able to deal with it because some engineering software does the same thing. As I said, I have not had one ocmputer go bad in 3 years. Indeed, I am not convinced that a steady temperature, even if slightly higher, is not better than constant thermal cycling of "normal" use.

As for the 50% rating when running on Intel HT chips: this is normal. It has to do with the fact that the HT chip imitates dual processors, when it actually only has a single physical processor. Since grid software fully utilizes the math portion, which is not divided, there is no benefit for this software to try to run both paths - I've seen expermentation and results and trying to run both paths. It merely splits the results for each in half, resulting in the same total progress either way.

Hope some of this helps.

hmm id rather be allowed to limit how much cpu time it uses. soon as i let it start running my cpu went up too 56C and i do not wish it to run that high for extended periods of time

i have been useing folding@home for a few years now and it gives this option . i think ill just stay with it.

Just my two penneth

The application is designed to halt when you run your Laptop on its batteries as it would seriously shorten your laptops "mobile" operations. It should only run when you are plugged into the mains
