Here is some suggestions and attempts about the "clock matter" of eSDK:

With you may be I woukd suggest, if still not yet attempted, to make eLink cluster / matrix working with the old ubuntu, then what about to try recompiling the last ubuntu img including the old eSDK that made eLink cluster working as it was done now with your work?


Hi, Claudio.

I tried recompiling the old eSDK under parabuntu 18.04, but I had lots of problems: Nick Lombard has got a lot further!
https://github.com/supercores/epiphany-sdk/releases

I tried, trivially, to use the last ubuntu 2016.11.1 simply putting the old eSDK 2015.1 into /opt/adapteva and it didn't work.


I tried that too, but it didn't work so I tried recompiling it from source: Please read Nick's posts about it on GitHub:
https://github.com/parallella/parabuntu/issues/19

Would you let me collect all the suggestion I received to work on it ? I can get all them from the threads and publish again here.


Yes, I think it would be very useful to collate all the information and post a summary on the "supercores" project:
https://github.com/supercores

My cluster now does work with 64 cores and I can use it for my project.
I'd like to run the slaves epiphany at boot, in a way they are ready to work in matrix.
Then acting only with the Master board and Master Epiphany to load all the task, synchronize and getting the results.
Better if it will work with hdmi and last ubuntu release.


I think it is a mistake to use a non-LTS Ubuntu release, which is why I'm working on 18.04.

My best, yet still really interested in Parallella experiments.
Nvidia (xavier I have) doesn't permitt to load different tasks for each core.


Thanks, it's encouraging to see a flicker of life left in the Parallella community :-)

The limit is to have a NON-HDMI FPGA setting for this release.

Hi claudio4parallela and ajtravis,

Hope you are all healthy and safe these COVID days...

I've had my boards (desktop hdmi w/z7010) for several years, but I'm just getting around to setting up a 4-board cluster and would prefer to use the e-links via Porcupine adapters. I've read the earlier comments concerning all the issues with compatibility between the OS and ESDK, so because it's been a while since the last posting I'm wondering:

1. is there now a recent OS (at least 18.04) and ESDK combination that provides functional e-links? And if so, is there any rebuilding required? I'm assuming that the OS would be headless...
2. if a recent OS + ESDK combination is still unknown at the moment, what would be the next oldest releases to use? I'm assuming that the OS would be headless here too...
2. it's not a huge deal, but is it possible for an hdmi OS and appropriate ESDK to have functional e-links? And if so, what rebuilding if any is required?

I've been looking through the forum categories and all the Git repos including Supercores to get myself up to speed, but any suggestions as to how to proceed would be greatly appreciated!

Thx,
Ross

Hi, Ross.

Well, I've had my Covid-19 vaccination now...

Nice to see a little activity on the Parallella forums again.
I've not done anything with my Paralella's recently either, but I have bought the Porcupine boards and e-link cables, so I'm interested in hearing how you get on?

I've not looked at the Supercores repo for quite a while now, because I've been using a Pinebook Pro and Rock64 SBC, but I am still interested in the Paralella, but probably running Armbian if I can get it to boot: https://www.armbian.com/

Thanks for posting,

Tony.

Hi Tony,

I haven't had my vaccination yet - they are rolling out by age-group in Vancouver, Canada so for me that means probably in the next few months...

I've received a couple of porcupine boards and the ribbon cable and connectors for the e-links, so I'll be working on getting things put together and tested shortly.
I'll post again with my results.

Cheers,
Ross
