Hi all,

 

This is my first post after reading all the good work this community has done.

My goal is to create a cheap cluster of ARM boards. I started with the RPI3 but that's getting expensive real quick and the board isn't that good performance wise.

So I started looking for different, cheaper boards but it still wouldn't be cheap enough if you plan to run 30-40 of them.

So I started looking at older Smartphones with OpenCL support and came to the Samsung Galaxy S4 (The Exynos version).

It is an older phone but once was one of Samsungs flagships and still offers good performance for what I want.

 

I know the Exynos 5410 was used on the Odroid XU, so in my opinion (and knowledge) it could work.

The boards sell for 10 - 20$ on Ebay and complete phones are also cheap.

 

My question, could this be done?

Is it as simple as just flashing the Odroid XU package on this phone?

 

Thanks for your help and information guys

Be careful since Armbian only supports XU4 (based on Exynos 5422 instead). No idea whether flashing old ODROID-XU images to a cellphone works (and I doubt people here do have the knowledge).

 

Anyway: an interesting alternative to RPi 3 might be NanoPi M3 (also not supported by Armbian currently but at least we tested the board already thoroughly ):
