when your CPU ist faster on AVX-WUs then on SSE-WUs.

it looks like boinc dosn't recognise avx on this computer of you
and your second computer gets avx-tasks.

so no problem?

Asteroids doesn't know if my 5005U is faster with AVX because it doesn't send any.

dose boinc recognize your avx cpu feature?

The server software is supposed to try different apps to see which is faster and more reliable. However Asteroids doesn't have it configured properly so its not trying all the apps. BOINC project servers have a configuration parameter <version_select_random_factor> which isn't set high enough. They can turn on <debug_version_select> to debug it.

It needs at least 10 successfully validated results for each app before it can get an APR (Average Processing Rate). You can see the APR figures for each app when you look at your computer details under your account (on here, after you sign in). Its supposed to pick the fastest app and occasionally send one of the others to see how they go.

can you please answer my question?

that was the answer to my question. :) (I asked google about you cpu before I asked you about what boinc sees)

but with this information, I have no idea why this host gets no avx-tasks

Hi, sorry again for my low activity on forum now. I have raised number of the parameter so you can check now how server handles deciding which application to send.

This machine has never seen anything except SSE3 CPU units and Cuda55 GPU units.
My Ryzen 7 2700 (non X) rig is the same. Never done anything but SSE3.

My W3680 only receives SSE2 uits, not a single SSE3 unit. My 1245v2 used to receive AVX all the time but now it started receiving SSE2 as well. Is there some way to encourage the project to send the correct type of work units?

Seems like the 1245v2 was just related to the release of the new app and the server is giving me AVX now.
The W3680 on the other hand received 8 WUs of the new app, but all SSE2. Could there be an issue detecting SSE3(PNI)?

Since the Server Status doesn't show which kinds of units are available you could be getting what they have that works that also has the number of tasks you want instead of getting all they have all of one kind and then some of another kind, there's just no way to know that.

To be honest I thought the WUs are the same, just running in different apps - it is not unusual for the same WU to be computed by different apps.
Either way the W3680 not receiving SSE3 units is a long term issue of mine going months back. I could understand, if the project decided that the SSE2 runs better on the hardware than the SSE3, but how does it know, if it never tries?

That's something only an Admin can answer.
