From: Rafael Waldo Delgado Doblas <>
Subject: Re: Parallella: OpenCL


I have advanced with my experiments with native epiphany code. Now I have a
make target for linux-parallella-16 that loads in epiphany's cores the
source code that in the BF patch says that is to be executed in FPGA. I'm
using the shared memory to load the variables from the host to the epiphany.

It's still not working. When I execute "./john --format=BF --test" I got
FAILED (get_hash[0](0)) but at least I know that the write and read to/from
de shared memory works fine and something it's running on the epiphany

Best regards,
