I think it's gonna be a long, long time
 

[FONT=Trebuchet MS]Hey guys,

[/FONT]It's my first time on the forum, and i'm glad to be part of GIMPS :smile: I've been going for about 2 weeks and I used to a few years back aswell.

I've very recently (about 5 minutes ago) got a Pentium III @ 500MHz doing LL (100) "first-time" tests, and although already having a vague knowledge of how incredibly long it takes to do them, I was shocked to be told that it would take 626 days! :rofl:

I don't know whether it's worth the time and effort to let it carry on working, since it said that the exponent might be re-assigned after a year anyway. Any advice?

Cheers :smile:

My advice is to change the work type for that machine to TF-LMH.

Trial Factoring assignments are much shorter in duration. And those in the higher ranges (commonly known as LMH) are even faster and more well suited to your machine.

Also, a double check would be faster, as it is a smaller number.

[FONT=Trebuchet MS]Ah yeah thanks, i'm not prepared to wait nearly 2 years for a result! :smile: A lot of Elton John to listen to if I let it carry on! :rofl:

Hi. May be a good idea to change to Linux, use mprime instead of prime95 in order to optimize cpu resources, and if you have enough memory you could try doing p-1.

Coincidentally I already was using linux 32-bit mprime with nothing else running :smile: I've now assigned P-1 factoring.

I forget how much power those P3s use, but purely from an electrical cost perspective you might do pretty well with the P3. There was someone a good while back who put a bunch of P3 stuff together, about a kilowatt of power draw, I think. That person did really well from a total cost perspective and it might still be true for P3s.

You can do whatever you want, I'm just killing time with this post. :)

i would be surprised if a kilowatt-worth of p3s would outdo one cheap Q6600
plus a Q6600 would use maybe a quarter of the power and possibly cost less than getting a lot of p3 parts together

A kilowatt worth of P3's is very interesting

Combined with another suggestion I read earlier today, booting Linux without a hard drive using NFS and PXE, I can believe somebody got enough P3 processors to do more with a kilowatt than with one bleeding-edge standalone system that also requires one kilowatt. If you can find that story about the P3s I'd read it.
