The tasks are running very slowly on my Oneplus 8T Android 14 phone.

Is there any way to make them run faster.

And yes, I have enabled the advanced settings, and enabled all the CPU cores, an d high performance mode on my phone, and it is plugged in.

your phone uses a mixed CPU architecture
1x fast core
3x performance cores
4x efficiency cores

Using all cores isn't ideal due to thermal concerns. In your case, I recommend limiting usage to 4 cores.

The app already utilizes optimal ASIMD optimizations, so no further architectural improvements are possible. It's still a mobile device, so don't expect performance comparable to laptop/desktop/server PCs.

Thanks for the response.

Yes, I also found the best performance limiting to 4 CPU cores, but fortunately I will be upgrading to the new Oneplus 13, with the new Snapdragon 8 Elite chip, and it has no efficiency cores, much higher performance, and much better thermals, but for now, only this project works on mobile, so not really attractive, and especially not if the GPU cores can't be utilized as well.

einstein@home offers a beta (CPU) app, that should work on your Android

btw I recently tested my Ardeno 750 GPU:
1/ Primegrid performance (GFN) was terrible https://github.com/galloty/genefer22/issues/12#issuecomment-2558303608
2/ AP27 even worse. Unusable.
3/ Einstein (BRP4) was ok (like Intel iGPUs). However, there were server/platform challenges, so it may take some time for them to release it if ever.
4/ The Asteroids app cannot utilize the GPU because Adreno lacks FP64 support.
