I red you were in trouble with clock and other issues during your first attempts.

So I'll go deeple into tests with eLink speed.

What do you think if I'll test this eLink-Cluster system:

MASTER: I'll use last Ubuntu image 2016.11 that should have eLink at FULL SPEED
SlAVE: I'll use the Ubuntu old 2015 image that should have eLink at partial SPEED.

I'll adjust/devide eLink clock on MASTER so, this system I think will point out how to go back to previously working eLink feature via cable.

Thanks a lot, I'll let you know.

At present I'm developing applications over 64 cores (4 parallellas) and the environment works like a juice!
I'm still using pubuntu-14.04-esdk2015.1-20150130 without HDMI , headless.
Scientific calculation is welcome, graphics is possible only using libpng.
At least the Master Parallella should have lxsession to watch results ....
Each core could individually move one of this ? ( I'm working on porting this from javascript to C).
I'll notify the request, thanks

If you make modifications, you can submit a pull request to the original repository. I doubt this is a high priority item. You should probably coordinate with Ola directly if you have particular questions.

Please, after many attempts I'm still using the old version of "PUBUNTU 14.04-esdk2015.1" as suggested by "Parallella Epiphany Cluster Technical Report", written at Parallel Systems lab.

Any attemp to port the to the last eSDK 2016.11 Ubuntu image was a failure.

Question and request for help:
I've noticed that one of the important upgrades from old images to last ones was the settings of FULL SPEED to the eLink instead of the initial partial timing.
I'm suspecting that this is the reason why the Cluster described is not well working with last image.

Could anybody support me to change time clock, eLink TIME SPEED for eLink in order to have a slower clock and try the eLink Epiphany Cluster using a short flat cable between Porcupines with the last Ubuntu and eSDK available with HDMI ?
