ysapir,

Thank you for taking the time today, to create this guide. Listed below, is the output of the matmul-16 example, from my prototype board.

Matrix: C[512][512] = A[512][512] * B[512][512]

Seed = 0.000000
Loading program on Epiphany chip...

Writing A[1048576B] to address 00000000...
Writing B[1048576B] to address 00100000...
GO Epiphany! ... Writing the GO!...
Done...
Finished calculating Epiphany result.

Good to see Your log. Until our delivery (2013Q2) we have some time to [wait|read|learn|code|test|simulate...] Would not like to share Your device via a public IP with root login?! ... Congratulations(!) +1 . Regards, Gabor

Actually Gabor

When Sundance get ours (soon, I believe the snow has delayed it ) and get it going, then I am going to setup a "Dial-In" to allow our external/remote/home workers (one happens to be in France!) to get access to the Platform if/when required.

We currently do this all the time and have a 100Mbit/sec fibre to the Outside World and I can't see my IT having problems getting this to be shared to the rest of the World, as it's not shared with our own Network to avoid Firewall problems and latency delays. We also add a Web-Cam to show the LEDs flashing, etc. Only problem could be that the 4000+ backers wants to connect at the same time

I will create a new Topic if/when this actually is possible; the key to succcess is sharing

@Sundance

That's very generous!

I did something similar once. What I learnt: you need some mechanism to reset the device to a known state automatically. I booted my shared device (a SheevaPlug) from the network instead from flash and had the device powercycled automatically every hour. This way everybody could have root access and if anything was destroyed it would be okay again at the full hour.

The one thing you should keep in mind is that he Epiphany device cannot really be shared among users (at this time, at least), so you should have some kind of user connection management system.

Oops. 'To share Your device' was just a joke at my side. But(!) If You are not kidding then drop a message about the details to [me|us]. Well, seriously, later (later = ++year_now) on: I can imagine [open|shared|distributed] 'system(s)' based on Epiphany ARCH board(s). Regards, Gabor
