This is already done; the Pentium 4 dynamically freezes for 1 microsecond at a time when it is too hot. I've also got some AMD Athlon boxes that run 10% slower after I've been running them hard. This is apparently controlled by the BIOS, though, so I don't think it's that configurable enough to be very useful. You could rig something up with a temperature sensor (perhaps lm_sensors) and cpufreq. -- greg _______________________________________________ Beowulf mailing list, [EMAIL PROTECTED] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> ______________________________________________________________ ICBM: 48.07078, 11.61144 http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE http://moleculardevices.org http://nanomachines.net ------- To unsubscribe, change your address, or temporarily deactivate your subscription, please go to http://v2.listbox.com/member/[EMAIL PROTECTED]
