I got large (_0 and _1) with deadline 30.5h and now I can't finish older WUs. It isn't fine.

Where are optimized applications for miniCollatz?

Especially for my old R4770 :)

Wow! Ice, 100kk - very impressive!

Congratulations!

PS: I need to add some GPUs and we'll see who will be the first to 200kk. :)

I'm not Distinguished enough to get in the Top 100 multi-project BOINC participants ...

I don't have a problem
No problem? Fantastic! We need look at BOINCstats. :)

Simply set one GPU to MW (or GpuGrid) and the problem will be solved.

I understood or understand why I'm not on it but it's still Stupid somebody can contribute as much as I do & not Qualify to be the List.
BOINC (Berkeley?) promotes support of many projects. It's ok! I think you can have one for CPU and one for GPU. Is it a problem?

Really Stupid
No, it is simple. :)

Look at Top100...
he following users participate in two or more projects with a resource share of 5% or more


Now look at your RAC...


You're too monothematic! :)

1. Priority of the app = HIGH (P3). Time ca. 14:20.

2. Preference: programs.

3. Now, I changed P3 to "without P" and now time is ok (11:25 & 11:41).

Win7/64, 2xR4770, 6.10.11, 9.9, priority = high (P3), W0.7.

Time increased from ca. 11:20 to ca. 14:20. :(

GPU load 75-90%.

Win7/64, 2xR4770, 6.10.11, 9.9.

Yes, now P3 works. But... counting time is longer and gpu load is smaller.

Posted 3033 days ago by Robert7NBI
Fast execution times or lowest possible CPU load?
Usually, speed is more important (3CPU+2GPU). But, during the race (PG, Yoyo, Seti) lowest CPU load is more important (4CPU+2GPU). For me, of course. ;)

Gipsel, thanks for everything. Good job!

One question - P parameter work? I have W7 & R4770 & v2.04, but priority is always below normal (for p1, p2, p3).

The second one is already in the current version. If you use a 6.10.x client and look to your task details, you will find it too. The client tells the app on which GPU it should run
I can't find it.

It has been reported... no resolution yet.
Of course. ;)

Exactly the same situation occurred in the version 6.3.6. Other versions I don't know good.
