I need a program that will just run everything at max so I can measure the max power used on some systems. My 'Kill a Watt' meter should show up early next week.
SO run that CPU at max, using all memory, and keeping the harddrive spinning.
I can jsut do pings on the lan card for it to stay awake.
I have searched here and on the net and have come back with nothing.

Might try sys_basher - it has memory, cpu and disk stress tests.

Are you wanting max power for provisioning purposes? If so, the max power on the power supply or chassis will give you absolute max. 80% of that number is what it is rated for on a continuous basis, 100% is for max burst.
If you need a more accurate number (as the above is the rated Wattage, which /will/ be different than actual usage for safety purposes), you could run multiple of something like this: `dd if=/dev/urandom of={somefile} bs=1024k count=1024`. Depending on your processor speed, that won't keep the disks busy all the time which is why I suggested multiple running at the same time. What that will do is pull 1GB worth of random data (stresses CPU) and writes it as fast as possible to the disk. Running a few of those in a loop should give you enough time to see actual power draw. Shifting bits around in the memory register probably won't add too much power draw, as it is mostly CPU and chipset (just CPU if you are using AMD). The RAM stick is fully powered regardless.
Hope that helps at least a little.

No for UPS purposes. Actually some of these are 'portable' and I want to size an external battery.
I will be running a number of tests. Max, min, 'typical'.

APC has a selector tools on their website that takes the parameters of your system and tells you what model you need. Not sure how accurate it is, but it's probably fairly close considering how many things you need to enter.

Some real good pointers and I am going to check them out....

And sometimes it gives you a close number. I have used it in the past.
Actually, in this case I picked up 4 decTOPs. The specs say they pull 8W @ 12vDC. That is with the supplied 10Gb 3.5" hard drive and 128Mb PC2700 SoDIMM memory, and I assume their USB keyboard, mouse, and ethernet.
So I am upping the memory on some to 256Mb, and others to 512Mb (max for the system). I am pulling the 3.5" power-hungry (and heavy) 10Gb drive and either going with a 10-20Gb 2.5" drive (need an adapter for that), or two Compact Flash drives: 4Gb memory drive & 4Gb Hitachi MicroDrive. Add bluetooth, switch to a mini USB keyboard and Bluetooth mouse (would like a bluetooth keyboard, but too pricy).
Now the pwer supply states 40W @ 12vDC. Can I power three of these from the one supply along with a monitor:
http://cgi.ebay.com/6-5-inch-TFT-flat-panel-great-for-Car-or-PC-project_W0QQ...
When I run them as a proof-of-concept demo? How long can I run them on a 3500mAh 12vDC battery unit:
http://cgi.ebay.com/Slim-External-Universal-NiMH-Battery-for-most-Laptops_W0...
Will be an impressive poc if I do it from batteries.
So I want to know what I can expect these systems to eat, electron-wise!

Sorry for the HTML format - looked really bad in text mode in Evolution.
Selected returns from "yum search stress" with some 3rd party repos enabled:
stress.i386 0.18.8-1.2.el5.rf rpmforge Matched from: stress tool to impose stress on a POSIX-compliant operating system Stress is a tool which imposes a configurable amount of CPU, memory, I/O, or disk stress on a POSIX-compliant operating system. Stress is written in highly-portable ANSI C, and uses the GNU Autotools to compile on a great number of UNIX-like operating systems.
Stress is not a benchmark, it is rather a tool which puts the system under a repeatable, defined amount of load so that a systems programmer or system administrator can analyze the performance characteristics of the system or specific components thereof. http://weather.ou.edu/~apw/projects/stress/
spew.i386 1.0.4-1.2.el5.rf rpmforge Matched from: Spew is used to measure I/O performance of character devices, block devices, and regular files. It can also be used to generate high I/O loads to stress systems while verifying data integrity.
Spew is easy to use and is flexible. No configuration files or complicated client/server configurations are needed. Spew also generates its own data patterns that are designed to make it easy to find and debug data integrity problems.
cpuburn.i586 1.4-1.2.el5.rf rpmforge Matched from: cpuburn is a suite of assembly-coded routines designed to put maximum heat stress on the CPU and motherboard components by a P6/P5/K6/K7-optimized mix of FPU and ALU instructions. There are also routines to test RAM controllers (burnMMX/BX). Please note that this program is designed to heavily load chips. Undercooled, overclocked, or otherwise weak systems may fail, causing data loss (filesystem corruption) and possibly permanent damage to electronic components. Use it at your own risk!!

fio.i386 1.16.5-1.el5.rf rpmforge Matched from: I/O benchmark and stress/hardware verification tool fio is an I/O tool meant to be used both for benchmark and stress/hardware verification. It has support for 6 different types of I/O engines (sync, mmap, libaio, posixaio, SG v3, splice), I/O priorities (for newer Linux kernels), rate I/O, forked or threaded jobs, and much more.
It can work on block devices as well as files. fio accepts job descriptions in a simple-to-understand text format. Several example job files are included. fio displays all sorts of I/O performance information, such as completion and submission latencies (avg/mean/deviation), bandwidth stats, CPU, and disk utilization, and more. It supports Linux, FreeBSD, and OpenSolaris.

nothing I know heats up a CPU faster than mersenne.org's mprime in its torture test mode. heat is power. run one instance per CPU core using the CPU affinity option
then simulataneously run some heavy cconcurrent disk IO operation, like tarring large numbers of files disk to disk...
and, if you have a hard core graphics, run some kinda fancy openGL demoware (in Windows, with a nvidia card, I'd suggest running one of nvidia's geforce demo programs..)
