I'm sure there are others who would try to tinker with it to squeeze even more juice out of the code, with tricks like ensuring code and data alignment, etc. Loads of fun to be had.

We now have two excellent early demos of what a E16 can do. So what would these demos look like running on an E64?

@Andreas: You now have shodruck's open source code, can you run these demos in your labs on an E64 board, over a longer range of active cores?


I believe Adapteva will show the demo running on E64. :mrgreen:

That's inevitable (Amdahl seriality, etc), but the speed-up results should still be impressive.


I posted about that,

Adapteva should not ship it to me because thousands of people are still waiting their Parallella.
I can develop programs using my E16 board and Adapteva can port it to E64 board easily.

Once upon a time, PC needed one day to render only one frame of Ray-tracing animation. :shock:

Yes I can remember playing around with a program called "POV".

It took an age to render a frame just to find you messed a coordinate up and have to redo the frame.


Kind Regards,

Yeah indeed. :lol:
Today, it's in realtime, using only 2W!!
I feel just like I'm living in a science fiction movie...
The future is here NOW!!!! :D

You have come up with a real treat Shodruky. Many Thanks ! :-)

Like, ray tracing is the ultimate method of 'reality rendering' and in real time to boot. I am poring over your code as we speak - thank you indeed for making that public domain - as it has a simple production structure which I will adopt ( as the Eclipse approach is in flux at present ) :

host code + Epiphany code -> makefile -> run via script

Actually I once had a Pentium 90 that did such ray-tracing ( ~ 1995 ) and yes it was awfully slow. You could leave it overnite to punt out a few dozen frames ....

Cheers, Mike.

So, to be exact, you are developing on the Parallella via TTY/ssh under the native Linaro ?

That works well, evidently ?? ;-) :-)

Cheers, Mike.

Yeah, it's very comfortable for me. :D
and sometimes I use native Parallella X environment.

I've added "Play Mode".
You can play Blobubska manually. Enjoy! :D

and I want to do this with a kinect and multiple monitors.
64 monitors with 64 Parallella boards!!!! hehe...
Of course I don't have money to do this. :lol:
I'm considering entering it in this competition.

Ah, may your coding loins be fruitful ! :-)

[ Barbican are cool dudes. They have a James Bond exhibition here in Melbourne ( Victoria, Australia ) currently, presenting a host of JB stuff to witness the style and trends over time of that franchise. I even got to see the teeth that Jaws used, the actual Golden Gun, and that famous Aston Martin* ! :-) ]

Cheers, Mike.

* Well, one of them at least. Alas not the one with the machine guns, the rotating number plates, passenger ejector seat and pop-up rear bullet proof shield.
