The dual tasks per GPU is the real booster here though

Huh. That should never be necessary. :\ It should be all about adjusting the -m values.

Well, whatever works.

Ah, I see. And what does this do exactly? I'm now (possibly) gaining on the 4th place competitor, any further optimization is appreciated! 😀
 
I had not added an app_config to WUSS, due to the triple cards being packed so tightly and running near max temps already. But, Ken, I'm sorry to say, I added your config, told BOINC to read the config, waited...and nothing happened really. Temps stayed the same, still took 8m 51s per task, and the Utilization continued to jump up and down (avg unknown).

I then replaced the app_config with the dual task one, and the utilization flatlined at 99% used, the temps rose a bit, but holy crap, the time to complete, oh wow!

Single task again was 8m51s each. I was expecting to get just a bit less than double that once I was running 2 concurrently, so maybe 17m15seconds. But instead, they are completing in as little as 14m30s! (With an average of ~16m at the moment)

The Titans have far surpassed the other cards in regards to improved output. I'm impressed and a little excited and am hoping I'm not aggravating anyone by posting so much today and am hungry and am going to go eat now and.... 😛

Enjoying the posts and learning.
I've come to the conclusion that the best way to run DC nowadays is to have just enough cpu power to help gpus work efficiently. Spend the $$$ on gpus, mother boards and power supplies and keep the rest at a minimum.
 
Really depends on what you want to run though. Relatively few projects support GPU crunching, while ALL support CPUs. For example, how long has Rosetta been around, still with no GPU tasks? Worse, if a project does support GPU crunching, it's often AMD or Nvidia cards, not both (or one runs great and the other sucks). And then they often run out of GPU tasks, while having plenty of CPU tasks, lol.

We're doing pretty well in 6th; Tony's barely hanging on to his 5th place.

Thanks for the stats. I've lost BumbleBee and his 2 R9-280X's. Whether under load or not, he runs for about 5 minutes then the display goes out (tried both cards individually).

I don't have any spare equipment to troubleshoot with at the moment. He'll just have to enjoy his sabbatical.

So, I'll probably drop in the ranks. Fortunately there's not much time left for the others to catch up. 🙂

I'm shooting for 8 million on this day #2.

I needed 15.3M to do that, mission accomplished. I was hoping to make the claim that on the last day I'd pull 9M points, to continue the trend, but BumbleBee has prevented that claim. 🙁

So far so good, regarding BulmbleBee's resurrection, but not with any double slot cards. I've managed to revive him partially, using an antiquated pair of Quadro 4000's. Output is abysmal, but it's all I've got for the moment.
 
The race is over! Mostly-final stats:

Tony hung on to 5th place; the TeAm onto 6th. 🙂 That might be our best finish ever! 😱

Tony did more work this year than the entire TeAm did last year!

I say mostly-final because double-checks are technically needed; but errors are very rare. But you should abort any work you haven't finished, to speed up the cleanup. Then you should go join the F@H race. 😉
