Multiple GPUs for AI/number crunching.

Sat Nov 17, 2018 9:22 am

There has been some good work done on getting the GPU to do some serious number crunching and I was just wondering if a future version of the Pi could possibly include multiple GPUs for extra processing?
We really need to get kids into AI as well as programming and this may be a cheaper more acessible way to do it.

The Raspberry Pi all current models have a VPU VideoCore4:

When it comes to AI the low-cost Pi0/Pi0W respectively the embedded QPUs (rouphly speaking: 12 vector-processing units ) are an option (Details: https://docs.broadcom.com/docs/12358545, https://elinux.org/BCM2835_datasheet_errata )

(1) Qlib

(2) opencl

Generally speaking :
Videocore V :
16 QPUs (currently: 12),
register width: 16*32 (16*float) AND 32*16 (32*short float) witch would roughly doubled the AI performance.

In the meantime:
Multible Pi0s/multible Videocore IV:
