What exactly is the purpose of running all these copies of mprime? What exactly will it prove if the CPU can run 2 or 3 or 4 copies of mprime?

I mean, what sort of stress do you expect to put your server in its
life time? Or is this stress test that you are subjecting your new mobo etc just a matter of finding out WHY the damn thing HAS fallen over when it had to run at least a couple of copies of mprime plus whatever it was you ran at the same time? Will your machine ever have to be put under such a stress?
The question is what failure rate does the machine exhibit. One failure per 10^12 instructions sounds infinitesimal, but that's only about a thousand seconds of operation!
We need to know that our machines are _extremely_ unlikely to fail, and the only way to do that is to push them to their rated limits under the expectation that those limits are not overstated.
Thanks for the explanation, Randall. When I eventually get a quad-core I'll keep all this in mind.
Latest update - it was suggested I install 10.3, then upgrade to the latest kernel. Which has very surprisingly had the effect that I can now run one copy of mprime a lot longer than before. I had one copy running almost eight hours last night.
Well, there you are. Didn't fall over for ~8 hours - a lot better than ~20 minutes :-) .
May I suggest a nice Windows installation for you? They mostly work.
For me? No thanks, I am sticking with SUSE. Ciao. -- A fanatic is one who can't change his mind and won't change the subject. Sir Winston Churchill -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
