CPU time for Astroids on Nvidia GPUs, record way too little CPU time.
I think the points are linked. Compared to most GPU projects, we're getting a good 8 to 10x lower points than we should receive.

Can points be revised pls?

I'm not sure, but for me, this is fixed credits, nothing to see with the runtime of any WUs.

Time / CPU time for an "avx_win10" unit : 5558 / 5215
Time / CPU time for a "cuda102_win10" unit : 432 / 2

Both credits are 480.


And if you compare this to "Collatz", do not. Each projects has his own rules, and from what it looks like, here this is fixed credit for any kind of WUs you do.

No, I compare it to most other projects.
Asteroids and mindmodelling are 2 projects that give the lowest PPD.
Most other have higher PPD.
PrimeGrid, GpuGrid, Yoyo are a bit higher.
The Collatz is without a doubt, giving too high PPD.

GPUs can't perform all the smart operations that CPUs can.
Some projects have more limited multitasking possibilities than others. Some have none at all which is why not all projects have GPU versions.
Comparison of GPU project performance is thus futile - by the way you failed to mention milkyway and Primegrid Genefer GPU WUs.

It is reassuring that Asteroids gives the same credit per WU whatever the process.

The smaller the CPU involvement, the greater the amount transferred to the GPU. This should be considered a measure of efficiency - not the opposite.

In case you didn't notice, all projects I mentioned above are GPU projects!
They all run NVidia GPUs.
When I see Asteroids on my NVidia GPU running at 198W, I assume I'll get pretty close to the same points as all other projects that can make use of the hardware in a similar manner.
If we get to compare, Asteroids uses the GPU way more intensely, than Einstein, Milkyway (which I didn't add, because I run plenty of GPU projects), and Moo! Wrapper. All these projects use about 1/3rd the power of my GPU (75W/104W Milkyway/Moo! -180W for einstein), yet they give more than 3x the credit Asteroids gives!

I'm telling you, this credit system stinks!

It's not even close to measured out fairly compared to all other projects that use the cobblestone measuring unit!

I would seriously recommend Astroids to stick to the standard laid out here:
https://boinc.berkeley.edu/wiki/Computation_credit

Likewise, I'm complaining with the Collatz for using Q/HPP (8-16bit) computation, but assigning 64bit DPP PPD for it!
This system is totally unfair as well!


I think Asteroids need to update their PPD credit system for GPUs,
Especially when they regularly shut down, and don't accept WUs from people, allowing processed WUs to expire without the user being able to upload them!

Srsly dude!
Asteroids is in the wrong here!

MOST of the BOINC projects will, after a shutdown, offer some time to upload any processed tasks, and accept them even if their deadlines have expired, if the quotas for the WUs have not been met yet.

You may need to watch carefully to see how close Asteroids@home is to doing this.
