My slowest machine is a Coppermine Pentium III, 930 MHz or thereabouts. It has an Einstein RAC of about 100 and a SETI RAC of about 4.

Keeping it running for BOINC is nuts on a credits/power consumption basis. It is one of the household's primary PC's. Had I not just rebuilt both of the other two, I'd strongly consider replacing it. Maybe next year with a Penryn or some such.

I think keeping old machines running for BOINC on the theory they are cost-effective because paid for ignores the cost of electric power rather badly. So I'm afraid I disagree with the major theme of this thread.

My Q6600 PC will probably stabilize at a RAC about 25 times higher than my Pentium III PC. The system power consumption is far less than 25x.

Credits do not contribute to the Gross National Product. So, as long as my electricity consumption stays around 4 kWh/day, all appliances included, no AC, I shall keep my PII crunching 24/7. Cheers.

One of my cruncher´s is a PIII with 750 MHz. For a big WU i need one day to crunch.

Hi!
I enjoy free electricity and have 7 P3:s running SETI.
I live in a small apartment and sometimes I turn them all off to be able to sleep.
sometime soon I plan to buy me parts to build a new computer, and of cause run SETI.

Best regards
Anders

I win

I have a Pentium 60Mhz, 48 Meg ram, desktop, still crunching. Without opt app it took 36 days to do ONE wu. After Opt app it took just over 2 weeks for ONE wu. It's now crunching at Leiden Classical hostid=25542 and currently has a RAC of 0.37.


Wow, thats impressive!

Here's mine:133MHz

Some of you mentioned optimised apps that can speed up the crunching process. Are these official?

Where can I get them from?

They aren't official in the sense they don't come from Berkeley directly, but they are permitted for use on the project.

Get them here:

Check out the Optimized thread up above, it's a sticky post.

I guess this is the call to all Chicken chefs to clean out their pots and start anew with the new MultiChicken stew.

I will upgrade all of my rigs in the morning. (When they are not busy crunching Rosetta 'cuz of the dearth of Seti WUs). Sorry, gotta whine for the kitties. Don't understand why Eric and Matt cannot get enough splitter power online to put an end to this WU famine.

Initial indication says the new MB optimised app cuts crunch time for AR= 0.405xxx unit from 04:11 to ~03:10 (93% complete) using Pent M (dothan) @2.16GHz.

Andy

edit] Thats for MB unit

edit 2] My C2D is about 2.5 times quicker than Pent M
