Maybe you should try one of those "infinite binary loops", that were so popular a few years back. They were supposedly able to trash a CPU! ;-)
... I've never actually been able to ruin a cpu that was properly sinked and vented... what the PI routine does not do is IO, not till its done anyway. But what it does do if scale is set high enough is to force the memory requirements off chip... so it exercises not just the ALU, but the bus logic as well... and it keeps those flops toggling long and fast which in turn draws lots of current which in turn creates lots of heat. Most of the time the processor in a linux machine is pretty much sitting there idle... that has always amazed me also....
I guess you missed the ";-)". That "infinite binary loop" was a bit of nonsense, that was going around a few years back.
This reminds me... Some a years ago I came across I link where some guys overclocked a CPU and fried an egg on it while playing Doom. But hopefully this is not what is required here :-) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFGVpY9asN0sSnLmgIRAiA2AJ9QKtfw/RF7B3o8kAM1/0bl2QM0DACdE+IK MdF/7hvKYIvULs47sJ6uyxk= =c4Z5 -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
