Hi all,

Since my system has quite a nice graphics card (a GTX 570), I refuse to run sieves on my CPU as they take about 300 times longer. Since I don't care for these (mega) long units I just want to run PPS LLR and that's why I also unchecked the "Send work from any subproject if selected projects have no work" thingy. None the less I've received PPS Sieve tasks for my cpu twice already in the last week or so and it of course starts to run high priority.

Can someone explain this and/or provide a solution?

Thanks :)

As far as I know, the selection system does actually work, so let's start with the assumption that you've got something configured incorrectly. That's a good assumption to start with, if for no other reason than if it's correct the solution will be very easy to implement!

You want to run PPS LLR on the CPU and PPS Sieve on your GTX 570, correct? You should have your primegrid preferences set up as follows:

(For the purposes of this description, I'm assuming you're using the "default" location. If that's true, apply these settings to the "default" section of the prefernces. If you're using "Home", "School", or "Work", apply these settings to BOTH the location you're using AND the "default" section. It shouldn't be necessary to set both, but it won't hurt, and it might help.)

Set "Use CPU" to YES
Set "Use ATI GPU" to NO
Set "Use NVIDIA GPU" to YES

In the CPU selection column, select PPS LLR, and uncheck all the other CPU boxes. Make sure there's at least one box checked in this column!

In the CUDA column, select PPS Sieve and uncheck all the other CUDA boxes. Make sure there's at least one thing checked in this column!

Uncheck everything in the ATI column

Uncheck "Send work from any subproject".

A few things above may seem a little weird, but they have to do with some not-so-obvious behavior that has existed in the past and might exist today.

Hi Michael,

That's a pretty reasonable assumption, seeing how 9 out of 10 times computer problems are PEBKAC-things. Even with computer freaks ;)

Indeed, PPS LLR @ CPU and Sieve @ gpu is the plan.

I'm using two profiles for two different computers, the difference being that one is allowed to use the cpu and the other isn't. I haven't toyed around with this any further.

Oh and it mainly seems to happen when I first disallow new tasks, let it crunch everything and then reallow new tasks. Not certain if this really is the trigger, so I'm now just gonna try that a couple of times.

There is a known issue with the current BOINC server side that will send GPU selected items to the CPU. It happens most when a GPU and CPU request are done simultaneously. Right now there is no fix PG can do, the BOINC programmers need to fix it.

So either you watch and abort the units when they show up, or just grin and bear it until BOINC figures out a fix and it gets installed here at PG.

Thanks for the explanation Pooh :)
I'll just not suspend workunit retrieval and it shouldn't be a problem then.

Don't await a fast solution from the Boinc programmers. They are more interested in implementing a new credit scheme or other new features than in bugfixing.
Secondly PG does not update the Boinc software on regular basis because PG is no beta-tester for berkeley (take a look at the Aqua thread Credit rollback and you know what i mean). If a bugfix is really needed, the work will be done by PG itself. This is a proved way (done many times with great success) and guaranteed a maximum of project-stability...
