A13 Cluster & Linux-Libre Kernel
« on: August 14, 2014, 05:55:14 AM »
Is it possible to make a small computing cluster out of the A13 and have all the processing power and RAM and peripheral devices utilized by Debian natively? If so, how would I do it?

Also, is it possible to run the A13 (or any OLinuXino board) with the Linux-Libre kernel instead of the default kernel? Has anyone tried it? If so, was any functionality lost? If not, does anybody want to give it a go?

You can build a cluster from any Linux-capable hardware, but A13 does not have LAN (and WiFi is not an usable alternative). A10 or A20 will be probably better option. And there are many HOWTOs on web about the Linux clustering.

You can do it, but you will need to (back-)port too many things, eg. USB, framebuffer, GPIO, SD card driver and much more (look at the options which have SUNXI in it). IMHO there is no need to do it, because unless you want to use Mali graphic core, you can build a fully GPL-ed kernel, completly without any proprietary code.
