Feature Request: Port to ARM
scrypt.cpp wouldn't compile on ARM platform, because it's been optimised for IA32 architecture.
include <emmintrin.h>
ARM intrinsics are different:
include <arm_neon.h>
Intel has a nice guide on porting ARM code to IA32, but I am struggling to find any good reference on porting in opposite direction.
I am far from programming these days. What would it take to port scrypt.cpp to ARM?
I've highly experimental ARM NEON port on my fork. It's successfully running on Jetson TK1 ARM device, which also has 192 CUDA cores. Feel free to try it :)
@noxo could you please add x11 to your build? GPU mining on scrypt is pointless, the only way to make anything remotely profitable with the jetson is x11. I have two jetsons and have been using your build for a while now. It works but i would much rather have x11..
I would fork your code and do it but i wouldnt know where to start...
I can confirm it works on the jetson though:
