Is anyone aware of any programs/scripts to stress test a system? The basic goal, as I understand it, is to crank a bunch of systems up as far as they'll go to test out a room's cooling. At least that's what I've been told. Seems like a squirrelly way to go about it, but I wasn't asked...
SUN apparently has a Validation Test Suite (http://www.sun.com/oem/products/vts/index.html) which can be used on sun systems. Does anyone know of something similar for HPs?
Thanks for any hints/tips/suggestions.

Re: automated stress testing?
If you want to run your CPU's at full throttle, this will do:
# perl -e 'fork; fork; 1 while {}' #...creates FOUR processes...
For every 'fork()' statement you add, the number of processes rises exponentially. Hence the above would load-up four processors doing an endless loop.

Re: automated stress testing?
And the CE procedures is very similar to what you can do on in STM. Every HW component is excercised.
To get an idea run STM > Tools > Excercise
When using STM be aware that this is an intrusive test that should be run when the system is quiesced.

SolutionSupport Tools Manager (STM), which you should nhave installed has exerciser tools built into it for most major components. You might want to have a casual look at them via mstm (a text UI) or xstm (an X windows UI) to understand what they do. Once you're happy with them you can run it all from the command line using cstm (a CLI) like the following:
This example will fully exercise CPU and memory for 12 hours (720 minutes):
echo "scl qualifier cpu;scl qualifier memory;eop time 720 maxcoverage;exc;wait;eal;"| cstm
I seem to recall there are other tools for disk and network too.

Lot of possibilities and our colleagues in the
forum already gave you some valuable
references.
Take a look at more:

Others and me gave lot of interesting
options in that thread.

Re: automated stress testing?
As for the rest, thanks one and all. The information, particularly the cstm commands, was very useful. I appreciate it.
