Hi, I noticed the temperature of my laptop rises sharply during execution of a long R script that generates several hundred plots, all of them saved to files. No screen output. Temps reached above 90 Celsius degrees in the box and above 80 C deg in the processor. The machine turns on cooler at maximum speed and exhaled air is really hot. Tried similar operations (batch graphic and music format conversion) and temp rises were usual. System: laptop, Turion 64, Kubuntu Linux, Xorg X server 1.4.0.90, KDE 3.5.9, R 2.7.2 compiled with MBCS, PCRE, etc. Could it be fake due to an interaction of some R piece with system monitors?

Heat simply shows that R is working hard. Dieter
Why don't you hack a little script that looks at system load, temperature and date/time and writes it somewhere. Then you can load it into R and plot it nicely :-))-O Even compare it witht he desktop :-)-O el on 10/7/08 12:21 PM Alexandre Aguiar said the following:> Hi, > > I noticed the temperature of my laptop rises sharply during execution of a > long R script that generates several hundred plots, all of them saved to > files.

Lpatops are not for heavy lifting, they are Toys for the Boys. I run the .NA country code Top Level Domain Name Registry which is Java based. It supports an API called EPP and I have of course a clone on my MacBook (and on the Sexy Little Number :-)-O). I tested the EPP by writing a loop registering as many names as possible and noticed the fan turn on almost immediately. It became so hot that I worried and killed the Perl script. I am quite sure that this is expected behavior. What happens with the same script on a Desk Top? el on 10/7/08 1:50 PM Tom Backer Johnsen said the following:> Alexandre Aguiar wrote: >> Hi, >> >> I noticed the temperature of my laptop rises sharply during execution >> of a long R script that generates several hundred plots, all of them >> saved to files.-- Dr. Eberhard W.
