I believe that you have my e-mail address. Can you send me the current data that you have for the extended OBD exponents?

I'm collecting Rodrigo's results, filtering them and adding his work to yours. :smile:

Anyway, if Rodrigo sends his results to you, there will be a double or triple check about it.

I'm not sure what this sentence means! :unsure:

BTW, in case it helps to clarify things (and for the benefit of other readers), what happened is that a while ago Uncwilly sent me a batch of unpublished exponents for factoring up to 71 bits. I've been working on it since February.

Now since we're on the subject, I have a question. At the current rate, I'll be done with this batch come January. In the interim, GPU computing has taken off big-time, with a few folks turning in prodigious amounts of work to unprecedented depths. (I don't know what might be happening with unpublished ranges other than mine.) Once my batch is completed, should I dedicate my OBD PC to other pursuits?

Rodrigo:
IMHO, you should buy your OBD PC some Christmas presents...I have a basic GTX440, and a GTX480, both of which do OBD part time. Lavalamp has better cards than me...and undoubtedly a bigger power supply. I'm going to get a UPS in front of my power supply, too.

Failing that, P-1 work seems most needed for primenet, or you could look at some of the other factoring projects. You'll need 500M of memory free to make P-1 work, with an optimum around 1-2 Gig.

Christenson,

Thanks for the suggestions.

This PC we're talking about was the original motivator for me to investigate GPU computing. (BTW I feel terrible about not moving on the GPU wiki already, work has been overwhelming.) I'd hoped that by adding a suitable video card to it, I might bring this Pentium II system to a performance level closer to mediocrity. :wink:

Sadly, though, the PC has only PCI and AGP slots, and in any case there aren't any Windows 98 drivers for the CUDA-capable cards it could take. RAM is topped out at 384MB. So AFAIK it's limited to either Prime95 TF or OBD. I'd keep it on OBD, except that the assignment+reporting system isn't automated and I don't want to create administrative headaches with respect to who can do what, when.

(The GPU research wasn't in vain, though. I did buy a GT 430 for a 3.2GHz Pentium Dual-Core E6700 computer, and it's adding about a third CPU core's worth of LL output.)

Coughs and spits at all the cobwebs on a PII!!! Uh, if you want that machine to do much useful, get it an ubuntu CD and boot it up and do word processing and programming and such on it. Or get you some ECM GHz-Days with P95...that's only a compute-pony, and only if you get it a new CPU and motherboard, will you have a compute horse or two...

LOL -- well, I did say I'd wanted to bring the machine "up" to a mediocre performance level... :smile:

ECM with Prime95 on that PC? I'd never thought of that. Will look into it, thanks.
