I can\'t believe it actually finished! All up it took 16,128,271.02 seconds of CPU time... jeesh. I hope they get some useful science out of that puppy.

Congratulations! As you already know, it\'s very satisfying to complete one of these long Models. May you have many more satisfactions.

You are to be congratulated, too, for succeeding on your first Model, and the most demanding of Models at that, with no failures. Would that all participants could make that claim!

I see that you\'ve chosen a shorter Model this time. Good plan! Good luck with it.

Keep the dust blown out of the machine, make backups, and you should be in good shape. Thanks for your help.

Edit: Be aware that all the work we do is posted online by CPDN staff for climate researchers, worldwide, to use in their studies. Oxford doesn\'t keep our results under wraps. (This is, by far, the largest climate research project in the world and I, for one, am proud to participate.) Your effort will, no doubt, be put to good use.

Edit2: Service Pack 3 is available for WinXP. It\'s nowhere near as big a deal as SP2, but it might be worth your while to keep up to date.

And it\'s produced an excellent graph. Well done! I think Milo (one of the CPDN programmers) said that 12 research groups world-wide have already downloaded CPDN pre-crunched results for their own research. That\'s apart from the research being done in Oxford of course.

There are more details about research plans in the News thread which is at the top of this Number Crunching section.

BTW, is the 327 in your name a significant number?

That\'s a very good tip for everyone. I recently unclogged both of my CPU Coolers with my vacuum-cleaner. My Linux m/c was re-booting every now and again and my XP m/c did the same a couple of times. When I opened up the cases, I could see why. The cooling fins were completely clogged up with dust resulting in no airflow or cooling capability.

All back to normal now, except that my CPU cooler fan is broken (siezed-up) as it has been spinning at max rpm for over a year due to the temps.... oh well.

Now, I\'ll give my PCs insides a clean out every couple of months.

Neil.

Hi 327,

Congratulations on completing your first model!

If I may say, your PC should be running cm3inct trickles about x2 the speed it reports, say 2.1sec/TS on at T2500 @ 2GHZ. With this Core Duo 31W/100degC thermal CPU I presume this is a laptop? If you look back at the trickles between 17-28 September 2007 it goes from 60K seconds to 110K seconds per trickle. The CPU benchmark speed should report about 1864 FLOPS & 3855 INTOPS, yours shows 835 & 1786. You can run the cpu benchmarks in BM to check.

I have one of these that did the same to me last week, going into this half-speed mode. Possibly this is due due to \'Speedstep(R)\' kicking in, maybe it didn\'t come out of standby or hibernation alright. It could also do this from the BIOS settings or maybe cpu over-heating?

A reboot may be all it needs. Otherwise the PC/CPU/BIOS could need some tlc to get it back to full speed. Your latest HADSM3 should run about 1.9sec/TS on a T2500 and bring in your next result much quicker.

Let us know how you get on.

I\'m not sure how it works under Windows, but under Linux/Gnome the Gnome power manager defaults to not counting \"niced\" (lower priority) processes while governing the cpu speed. i.e., you can have a \"niced\" process spinning at 100% and it will stay at a low clock speed. I tell mine to consider niced processes so that it stays at full speed when boinc is running.
