Thanks Zalster! I am now testing this card first! seems to have a small increase on the previous card, however, we shall see over a few days of crunching :)

I have never created an XML file myself Zal, but at present I have removed the GT640 to test the GTX550Ti at present I am a little low on PC memory to run both also, system slows to a crawl. but I would love to know how to do it for the future :)

Thanks

Hi Mike!

Just a quick question! How do I get two GPU's to work at the same time? I have a GTX550ti and a GT640, is it possible to get the processing at the same time!

Credit is slowly creeping up!

I had a feeling it would take a while

Ok processing seems to have settled at around 7.8k and to be honest I thought I would have had more growth by now! Although I have nearly 80 units pending credit!

Another question while I am thinking about it! with the GPU it reports using 0.04 CPU and 0.333 GPU! is it possible to increase the CPU allocation to processing the GPU units?


With actual settings the GPU will get as much CPU resources as needed.


So you physically cannot increase the amount of allocation? shame, it would have been good to be able to have the option! Shame that BOINC doesn't have the option to increase WU's via the menu system rather than hacking files!

I had a feeling you were working with Lunatics :) As for the credit it has risen 200 points above yesterday, but I am wondering if I am pushing the graphics card a little hard by going with 3 wu's.

I have added the AP command line into the file suggested, Obviously you have been using these optimisations for a long time and know your stuff! I hope this all helps :)

Overnight I have seen an increase in performance, so again, I will monitor the settings! At present I am running 65% of the processors 100% of the time, with 3 standard WU's on the GPU or 2 AP's on the GPU. I have noticed that if there is 1 AP running it will still only allocate 1 WU to the other slot. Which isn't much of a problem for me.

Again thank you for your support!

Thanks Mike, that's one for the morning! I want to see what happens with the other changes overnight!

So use that exact line in your example!

When you read the AstroPulse_OpenCL_NV_ReadMe.txt you will notice there are some comand line options.
You can use them via ap_cmdline_win_x86_SSE2_OpenCL_NV.txt.

Example

-unroll 4 -ffa_block 6144 -ffa_block_fetch 1536 -tune 1 64 8 1 -use_sleep.

Maybe unroll 6 is possible but this requires testing.

Hmm, I think this one is a little past me! I have managed to get the multi WU's working on the GPU now.

What do you mean by the AP's need tuning on the GPU?

Mike, I can see you have the same processor as I do! What are your current Computing Preferences for SETI@Home?

I fully understand where you are coming from Mike! However, looking back over the last 40 days, when I was running a lower amount of cores, I was only getting half the credit I am now, that's what is stumping me!

I am running the Lunatics 0.42 right now so there isn't much I can do there! Rather than run extra WU's on my GPU, I may just add another GPU in as I have the slot for it. I am running all 8 cores on my system right now with very little slow down. But, does higher credit come from faster turnaound?

How, is it possible to increase your credit per core? I am currently receiving around 60 to 100 on average per core which to me seems a little low! Is it possible to increase this? Also is it possible to run more than 1 work unit on a GPU if so how do I do this?

Thanks, I just want the team to get the credit they deserve! Looking at most of the sites there, a lot seem to no longer exist! Well, we are here for the long haul :)

Don't forget we are forever recruiting :)

After, the email failing to send, I sent a private message through to David Anderson with success! We now have our team listed :)

Once again Thanks for your support!
