Re^2: OT: Parallel::ForkManager and suitable load (Ubuntu)

I just did a complete run, keeping an eagle eye on the temperature of the two cores.

At the start, the temps were 50C+44C. After starting the script with 50 kids, the temperatures climbed to about 80C+77C, by about a third of the way through. The 'high' value was 80C, and the 'critical' value was 100C, so I watched to see if the temperature got significantly closer to 100C -- but they did not.

After the script completed, the temperatures fell back down to a normal range -- 55C+51C within five minutes. So at this point, I'm fairly confident that running with 50 kids is safe for the hardware that I currently have.

Thanks for all your input!

Modern CPUs regulate their own clocks based on temperature, so you can crank it to the max. The question is does the speed drop. Either way that has nothing to do with parrallisation If each job is purely CPU crunching you shouldn't see any improvement having more kids than you do cores.	[reply]
