I think he has turned on Credit Screw and the payout went in the toilet.

Yes, I think Eric has been persuaded by folks with hard-won CPU credit totals.

32WU doesn't work BTW - probably because it needs more RAM than the card has. Now trying 16WU and only 4 cpu threads

Eric did implement credit screw and the payout crashed to being not worth the effort.
He has now changed it again to a fixed credit. I just got 4000 for a task. Better than 12 I suppose. Least he seems to have listened to our complaints.

Dear dear dear - I must be getting old. I had forgotten one key part in making this work for all TSBT group members.

Sorry about that Gents - you should see a heckuva difference now since almost 20 other project forums had the same problem. Hopefully all sorted now

I'm never exactly sure which techniques we discuss in open forums vs. what we discuss in 'pirates' forums TBH.

That said, I reckon deleting this particular thread wouldn't be a huge loss since it is pretty irrelevant after two separate adjustments to the way project points are awarded !! Up to you, I don't mind either way

I'm just messing with it. Changed it again before I seen your post, so month is in 3 letter format rather than numeric. Is there a time format ?

Would appear that the GPU tasks have now started paying 8000 per completion. Looking better than the credit screw crap.

I note on Saturday that the credit was messed with again. 800 points for the GPU tasks now. Not worth running my GPU's on the project for that level of points.

I reckon Eric must be getting grief from his users who have big totals earned on CPU crunching. If that is indeed the case, they need to wake up and smell the coffee - a GPU app basically obsoletes the idea of crunching on a CPU. Plus, if you want people to deploy their GPU on your project, you've got to credit at or near the going rate

Well here's a simple number for Eric. In all the years of running numberfields on a CPU, I found 7 decic's. Since the GPU app became available, I am now up to 18. If he can't see that simple fact what's the point ?
Apparently he had to drop the GPU credit because it was making the CPU credit too high. Why he can't award the points based on whether the task was run on a CPU or a GPU is beyond me. Every other project manages that simple task.

Just posted this over at the project.
In my opinion, the change to 800 credits per task on a GPU is far too low.
Here's a simple number Eric. In all the years of running numberfields on a CPU, I found 7 decic's. Since the GPU app became available, I am now up to 18 in about a week of running on only 2 cards. I'm sure this will be replicated by everyone else running GPU's here. I believe you are quoting that a GPU does 20 x the work of a CPU. You need to encourage GPU's not make the project not worthwhile crunching compared to other GPU projects.
Apparently you had to drop the GPU credit because it was making the CPU credit too high. Why can't the award of points be based on whether the task was run on a CPU or a GPU ? Other project's manages that task.
The increased numbers of decic's found by just myself should indicate how much more work is being achieved by people running GPU's and should encourage you to award and attract more crunchers to use that platform. On most projects, the introduction of GPU apps makes the CPU app almost obsolete.
Think that is a fair comment. If it doesn't change soon, I'm out and back to Collatz , Enigma etc. I did want to make 20M on the project but not going to run my GPU's for weeks to achieve that.

What he is saying is that with fixed credits you will get the "correct" payout for both the CPU and GPU work done. If the GPU crunches 20x faster then it will earn credits equivalent to 20 threads of a CPU. In his world that is enough incentive to run his GPUs on the project because your real reward was finding decics for science.

In MY world it isn't paying enough to give me incentive to spin up the 1080Tis. In my opinion, with the exception of a couple of projects, all projects are running good science so I will choose where I'm willing to use my resources. I'm a credit/badge whore and NF isn't paying enough to tempt me to pay a higher electric bill to support the GPUs.

But the real reason is I can't run them on Linux :lol:

Yes sir, tis a fact :x

I will be returning home in 2 more weeks and I'm going to try upgrading from Mint 17 to Mint 19 (clean install). On the 2990WX machines it picked up the GTX 1080Tis during the Mint 19 install. I'm hoping it will setup both the Aspeed GPU and the Nvidia. I'll connect a monitor to eachone and see if it can figure it out.

I didn't leave the Nvidias in the 2990WX machines because dumping heat into the chassis* raised the temp on the CPU so I couldn't overclock it.

* Yes I know Steve, I should have followed your advice and bought the water cooled GPUs :doh:

Might I suggest Ubuntu 18.10 as that is a fair bit newer than mint 19. Or is it the older kernel you want for performance?

My thoughts exactly. They get free science off my money. If they can't be bothered to incentivise me with free credit then why should I bother. If the credit is Einstein or above, OK. Below that, seti, asteroids etc then I will not waste my time. That's the projects choice. Don't get the holier than thou attitude, either they want my GPU's on their project or they don't. Think that is pretty simple.
