Easy, Fast, Cheap Way to Generate CPU Load?

jsailor asks: "A large client and their engineering team will be evaluating cabinets and their ability to cool high density blade server deployments. Some of these systems can consume upward of 21 kW per rack and accordingly require a lot of airflow and/or liquid systems to cool. The systems actively monitor heat conditions, increase airflow rates, and can throttle CPU speeds if necessary. What we need is an easy, fast, and cheap way to run the 2-way and 4-way blades at or near peak CPU utilization for extended periods of time so thermal analysis can be performed. Ideally, we would be able to boot them off a CD and have some means of monitoring the CPU on each or even setting the level of CPU utilization we'd like them to run at. Please note that we do NOT need to simulate a real world application and disk and network access are not of much concern. While running your favorite compute-intensive project is a nice idea, we need something simple so I've come to the Slashdot community for assistance. What are your thoughts?"

Endless fork?

[mooingyak]

maybe a simple script like:
#!/bin/sh
sh $0

or in c

while ( 1 )
fork();

Always do it for me. The Vonage ones are the best, especially when you end up with like three of them on a page. Sometimes I swear they can even spike the cpu load of other machines in the same room.

My little forum that I run, has a bank of animated GIF smileys you can choose from. When you open the page that gives you all of them at once to pick from, my CPU pegs 100%.

Animated. GIF. Smileys.

Other people use their processing cycles to find puslars. Me? I use mine to have little yellow smiley faces chase each other around with machine guns.

You want load?

Post the address on slashdot.

First, make it into a server

[AtariAmarok]

First, make it into a server. Host a web page on it, perferably about a popular topic like Star Wars. Next, successfully submit a Slashdot story that links to it. You'll be overloaded in no time.

boo!! my infinite loop is far superior!!

int main() { for( ;; ) ; }

EDIT.COM

[mosel-saar-ruwer]

Back in the day, the old MS-DOS editing program, EDIT.COM, ran a polling loop that would drive the CPU up to 100%.

The Intel guys used to recommend it as a way to stress test your system.

Easiest way

Oh, Slashdot, why are you so placid and intolerant of a good old-fashioned flamewar these days? I had to scroll through two pages of boring serious answers before finding this, the proper reply to this story.

Slashdot community is simple

Thanks! I think...

Re:infinite loop in java

[Tet]

Who needs an infinite loop? Just running running any java program should be enough to consume all of your CPU cycles and bring the system to its knees...
