I have finally ventured into CUDA crunching with a rather ancient GF8800. I only set this up yesterday and the original "Time to completion" was around 28 hours, the actual completion time is between 15-20 minutes.

My question is how long before this becomes closer to the real time. At the moment I am only getting 3 or 4 CUDA WU's at a time, this will obviously not last long during the outage. Is there a way to correct this.

It will get better over time, but you can support BOINC, as you are running anonymous platform. Look for threads that contain "flops" or "<flops>" over at Number crunching.

Welcome to CUDA crunching Bernie. Isn't it fun watching that little GPU fly? I see you got the latest Lunatics offering and plenty of work now. Looks like you are good to go.

Yes all is now good, the time to completion suddenly dropped from 26 hours to around 30 minutes. So I have picked up plenty of work.

I wasn't sure how long it took for the system to adjust, I read in another thread that it takes 10 validated results.

Yes it is very satisfying to watch a WU "move up the queue" and finish in minutes rather than hours. So much so that I am thinking of getting a cheap CUDA card for another of my machines. Any suggestions?

Depend of how much € you would like to pay.. ;-)

'Advice on graphic cards'

If max. ~ 116.- € then maybe a manufacturer OCed GT240.

Looks like you didn't wait for us Bernie. That's quite a nice little army you got going there now. Are you going to do the other two machines too?

Well I actually started a thread over in NC.

http://setiathome.berkeley.edu/forum_thread.php?id=61331

Where I did get a fair amount of advice and the GT240 seemed to fit the bill all round.

As to the other two, depending on the results from the other 3, 4241618 http://setiathome.berkeley.edu/show_host_detail.php?hostid=4241618 will hopefully get a CUDA card next month.

However 4212602 http://setiathome.berkeley.edu/show_host_detail.php?hostid=4212602 is a CCTV machine I look after for a local charity, I haven't actually physically seen it for many months.

I was going to resurrect this beast 4489474 http://setiathome.berkeley.edu/show_host_detail.php?hostid=4489474 is also has a GF8800 512meg, but it is my main machine I use for gaming and surfing and I prefer it to be idle at the moment.

However we will see how things go.

Bernie.
