The only \"64 bit\" models here are slabs. (32 bits in disguise.)
See this page.
So, provided you haven\'t excluded them in your model types selection area, BOINC will automatically send you some.

The main benefit is a larger address range, for more memory.
It\'s been reported that a small number of projects (count them on the fingers of one hand), do run faster with 64 bit systems, but most don\'t.
This project, for instance, uses 80 bits of resolution, and there is no difference with this for the floating point unit (FPU), in 32 & 64 bit OS.

PS
The \'64 bit\' models here are just 32 bit models wearing a mask and cape so that they appear to be a more powerful 64 bit model.

[I\'m willing to bet money it\'s Vista. Are you happy with Vista? Or could you go back to Windows XP? If not, then are you running the 32-bit BOINC or the 64-bit BOINC? (Does it say x86 or x86_64?)

It really does help when members report problems and anomalies on the forums. It also really helps that CPDN members are almost invariably good-tempered and patient even when discussing the most difficult problems!

Ah -- I was wondering about that. I\'ll not whine until Wednesday evening then <smile>.

Barry, I couldn\'t check your current model trickles because there are so many computers and so many models..... And I couldn\'t whether your recent trickles are all present and correct, Arion, because your computers are hidden.

Looks like, notwithstanding that the outage was only a couple of hours yesterday, data the trickle update statistics outage is still in effect for a second day.

See, I told you I\'d be back this evening to whine. (smile).

I came home expecting to see very few points from my Boinc projects (I run Rosetta, CP, World Grid, Spnhenge and Linden)

Anyway I look and I notice a BIG bar on my daily credit graph. Then I notice that CP gave me just over 2000 points! At first I thought my model had died on me, but it was still fine. So how did this happen??

Hi Arion and welcome.

Remember that the cpdn workunits are massively long compared with other projects, so a few extra precautions are required here to avoid disappointment. I\'d recommend a look at the project READMEs linked through my sig. Don\'t try to read the lot!

I would like to first ask how many of you leave your computers running to crunch as much CPDN as possible?

Secondly, do you know where the electricity that your computer(s) uses to crunch comes from (or that delivers electricity to your electricity outlet comes from)?

Thirdly, have you ever considered that leaving your computer on to crunch CPDN data is a contradiction?

The reason I’m thinking this is because in many countries fossil fuel is used to generate energy and this is one of the main reasons we have global warming today. So ask your selves next time you leave your computer on to do some crunching: Why do I participate? If the reason is to get at better understanding of global warming and maybe find a solution, then turn your computer of when you are finished using it. It will be a contradiction to leave it on just to crunch data.
