Don't mean to burst your bubble but......

Your basing your ideals of how well your machine is producing based upon one week old Rac?

It's going to take two months of solid steady crunching for Rac to stabilize sufficiently to be any judge of how well a machine is producing.

I've got a machine that is producing 12.8 million a day right now all by it's lonesome, but it's Rac is only 3.2 million.

So your producing at 227 seconds per WU on average. that is roughly 380.5 WU's per day, (86400 sec/day divided by your 227 per WU)

That 380.5 WU per day times the 27200 credit per WU average your getting equals 10.35 million per day.

Pencils out right where a 1080Ti should be,. twice the Rac your now demonstrating.

We have been doing this a while.

That machine will probably be down below 20th position when the dual machine Racs catch up.... Pretty much average for a single 1080Ti....

I have found that with one WU on an Nvidia 1080 Ti the GPU is only ~65-70% busy.
That's why I let 3 WUs run in parallel, so it is also ensured that the pauses are filled in when terminating/starting the WUs.
one WU needs 5:32, three WUs in parallel need 11:12 each
I control the GPU load/temperature with the MSI Afterburner.


Sounds to me like your not using the configuration file....

Start using it and you will soon drop to one per GPU....

Two (or more) per GPU for me resulted in WU's erroring out at a far greater rate than any benefit gained..

Probably a dumb question, but I don't know how to remove and re-attach the project?? The "Remove Project" button in BOINC Manager is greyed out, so I can't use it...Any ideas..Much appreciated!

On the project screen in Boinc Manager highlight the Collatz entry in the project listing section and the remove button should light up.

Hi Jon,

As offered I've setup my last dual 7990 machine on this and it's been running for about 6 hours now. I'm using the exact same setup I was using on the old WU's. The WU's seem to be completing in the same amount of time 12.5 minutes on average for both the 7990's and 7970 I've got it on.

The 1080 is doing them in about 5.5 minutes so far without error. Will let you know if I run into anything strange.

One thing to note, the server is giving out a cache of over 1k WU's per machine.(almost 1200 in fact) Previously it was giving out 100 WU's per GPU to ease potential server issues.

I know there are many many details that need to wait cause of more important things. but this is one that you should probably put on the to do list....

And let me know if you want the new badges I designed I still have them if you want to implement them in the future.

There is no AMD OpenCL App ?

On https://boinc.thesonntags.com/collatz/prefs.php?subset=project there is only:
use CPU
use NVIDIA GPU
use Intel GPU
but no AMD GPU !


I'm sure there is one coming.......
Be patient..... :-)

What I am noticing as the work gets validated is that the credits seem OK but the accumulated credits are not getting incremented properly. So I see a credit award of 35K for a unit but my total credits get incremented by 350...


Probably a misplaced decimal point...
