How can I load every core?

I have never had a PC with 4 cores and now I need to find a way to load every core so that I can make sure my cooling solution will keep the system stable. I have tried running multiple SP2004 Orthos Editions but it only loads 2 cores no matter how many I have open.

Any ideas on how I can load these cores?
 
Let me get this straight, you built a 4 core system but can't max it? Why did you bother with a quad core build, then?

I mean, don't you generally want to build a PC that fits your needs, or at least, doesn't exceed them to the point where it's just wasteful?

Would you level the same criticism at everyone that uses a stress-test app to confirm a new (or newly overclocked) system is operating correctly? Or would you instead acknowledge that they are following a reasonable testing procedure before putting a machine into service?
 
Thanks myocardia, that's exactly what I was suggesting. I'm glad somebody got it.

But I'll give the OP a hint here. 4 cores is nice for a (very loaded) database host. Load it up with Oracle (scales almost linear over CPU's) or DB2, and see if you can max it. Be sure to put enough memory in it too, though. 8 gigs min, I would estimate.

To aluvus: If you even believe, remotely, that you need 4 cores, you already know how the "reasonable testing procedure" to run before putting it into service.

get orthos, its like the dual coare version of Stressprime 2004

then jsut run 2 copies of orthos, or u can run 4 copies of stress prime at the smae time , just assign them to each core, ie core 0 to core 3


stressprime:

i read somewhere that 2 copies of orthos doesn't load 4 cores.

you need to run 4 instances of stressprime.

where i read it... i can't remember 🙂

That has to be the worst comparison I've ever come across. sj was merely saying that if the OP (or anyone else for that matter) doesn't already know how to use all 4 cores, then it's quite obvious he didn't need more than two cores to begin with.

What if the OP's primary use is one application that quite happily takes advantage of additional cores with no special instructions from the user? IOW, what if the OP never needs to do something like setting affinity in normal usage? You are assuming that the OP needs special knowledge to make use of all 4 cores, which may or may not be true.

Forgive me for not following the "jump to conclusions and then berate people" strategy.

I was told to build a dual Woodcrest system that would be used by a fellow associate. He can easily max it out with all the code that he compiles regularly and the scientific calculations he does.

The heat sinks that I ordered for the system sounded like jets taking off so I have to come up with a different cooling solution with the parts I had on hand. After building the rig I wanted to make sure the system was stable with the cooling solution that I came up with. If I had handed over the PC to the person that was going to use it and it was unstable I would have put my job at risk. Since I had never used or built a system with more than 2 CPUs (or cores) I was at a loss as to how to load ever core.

Either way I figured it out and after 24 hours of stress testing everything was working great and I am now working with a very happy geek.

Yeah, and stop building cars that can go over 70 mph too.😉
