On my GPU card Nvidia RTX 4070 Super when I am running primegrid tasks GPU and Power usage is nearly on 100%.
But with Asteroid@home app GPU usage is 100% but power usage about 50%.
Does anybody know why?

Check your Boinc settings for any restrictions on gpu usage or memory usage. Your computers are hidden so don't know whether they are Windows or Linux based. Could be Windows power settings I suspect.

I run 2X on my cards with a custom application and they utilize all the power I allow them to use.

On my GPU card Nvidia RTX 4070 Super when I am running primegrid tasks GPU and Power usage is nearly on 100%.
But with Asteroid@home app GPU usage is 100% but power usage about 50%.

Tohle je častý problém mnoha projektů, sám nevím co to způsobuje, někdy pomůže spustit paralelně další výpočet
například

<app_config>
<app>
<name>period_search</name>
<max_concurrent>30</max_concurrent>
<fraction_done_exact/>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.01</cpu_usage>
</gpu_versions>
</app>
</app_config>

uložit jako app_config.xml v tomto adresáři
C:\ProgramData\BOINC\projects\asteroidsathome.net_boinc,
v Boincu pak dej možnosti -> načíst konfigurační soubory
u některých projektů se vytížení zvýší na plno nebo téměř na plno, samozřejmě se úměrně tomu protáhne doba výpočtu,
ale to je v tomto případě asi jedno, jestli děláš jeden výpočet 5 minut nebo 2 paralelní výpočty 10 minut.
Vzhledem k tomu že někdy tato úprava configu pomůže, tak bych řekl že je to chyba aplikace která je zastaralá a nebo neoptimalizovaná pro dnešní výkonný HW.
A ještě k tomu nastavení, když z toho chceš vyždímat maximum, mužeš si všimnout (při výpočtu 2 úkolů) že při dokončení jednoho vytížení GPU spadne zase na polovinu, je to tím že chvíli trvá než se nový úkol rozjede, z toho důvodu já někdy používám nastavení
<gpu_usage>0.33</gpu_usage> pro 3 paralelní úkoly
<gpu_usage>0.25</gpu_usage> nebo pro 4 paralelní úkoly
to aby grafická karta byla vždy vytížena aspoň 2 úkoly

the Asteroids GPU application is heavily constrained by random memory access. this slows down overall computation A LOT. your GPU is waiting around for memory transfers more than it's actually computing, that's why the power used is so low, because it's not working that hard. it's not a problem, its just the nature of the application.

Primegrid is just crunching numbers, and doesnt have the same reliance on VRAM transfers, primegrid tasks mostly fit within the L2 cache on the 40-series cards from what i remember, and they are more optimized than the apps here. you basically can't compare two apps that are doing two totally different things.
