x=x(k,t); y=y(k,t); z=z(k,t)
that is working using a double loop, one numeric (for i=0;i<width;i++) and the other one through the parallel calculation of cores both in a single board asset of 16 cores or using a cluster of Parallella boards using boards*16 cores (in theory up to 8 boards, 128 cores).
Using a single board (16 cores) or a cluster (for example my 64 cores cluster) it is possible to run multiple cycles in parallel: multiple of 16 cores if using a single board or multiple of 64 cores in a cluster of boards in order to process the evolution of trajectories of f(x,y,z) one by each core.
The Host program has a run.ini file in order to run options:
axis yes/no; frame yes/no; assonometry view yes/no; +-zoom value; rotation xy, zy, xz; boost x y or z; step length; number of parallel batteries of cores; number of boards used.
Each core run its own program to model and calculate its f( x(t,k) y(t,k) z(t,k) ) in a form of a template to realize the evolution of the parametric functions.
Actually I'm running and using a cluster of up to 4 and 5 boards with 64 and 80 cores in a cluster of epiphany chips via eLink (North/South gates).
I'm going to apply Runge Kutta applications for 3D derivation of f(x,y,z) through 3D trajectories.
I can only image what we could do if it would be possible to using an access to a Framebuffer or an HDMI output.... still I've not been able to use any HDMI version of the Bitstream.
I hope someone could be able to add an HDMI and a Frambuffer to visualize dinamic 3D functions.
I'm available to share cluster setting and my application to work with multi cores boards.

Did you find a buyer for your 4-board Parallella cluster?
If not sold, what boards are they - desktop or server, 7010 or 7020?
Were you also able to get a newer OS installed with clustering and HDMI supported (if desktop boards)

has anyone tried to write a software renderer for parallella?

A phone or a tablet is being used to mostly read a book while listening to music or switching between video watching and book reading.
So most of the time when a tablet or a phone runs it only needs little graphics transformations raw photos video audio decoding (but with spotify there wont be much other possibilities for listening to music the way it was introduced by itunes), font rendering.
Apple iPad, being a particular case since desktop publishing photo editing music making, recording and mixing (with hundreds of audio tracks and audio plugins) is in apples dna but I'm not sure one would need to write a video editor with desktop plugins in order to know.
Most complex applications usually dont "collide" in terms of running concurently.
Audio video decoding could be paralelized by "turning video off" making the zero (epiphany 64 core?) a powerful chip for xy sliding photo (couple of seconds) transformations and color editing transforms or more complex effects with detection features.
I do not think image signal processing or AI circuits are necessary in order for a future zero chip to compete on mobile market since many applications on googlestore are useless (even games).
One would probably need to port android (glodroid etc) in order to show that the chip is capable of running apps important for every user.

I'd like to ask whether the project is still alive? I thought the difference between octacores risc-V and epiphany would be that epiphany is something like a DSP processor whereas octacores and hexacores are central processing units adding cores
So epiphany should still be faster then current hexacore processors or am I wrong? Also the idea of throwing out the FPGA and having a dual core single chip with integrated epiphany (if its that simple
) would create at least a very interesting competing board if not a mobile platform which doesnt necessarily be a mobile phone.thanks for answers,
Marek

If I have some time over the next few weeks, I'll try to get some kind of system image going, but I need to look at a few things like the expanding filesystem scripts, other details, I have a github and will post a link if I make any progress. I think it would be best to go with a longer supported Ubuntu image, however, looking at e-gcc, and some of the parallella specific stuff, it will be a steep learning curve.
Who would have the best info on 7010/7020 support?
Sorry I'm late to the party, hopefully there are still a few people interested in this project. It's great for development.

I have a well working and ready cluster of 4 Parallella Adapteva boards with 4 Porcupine Boards and eLink interface that I do not use anymore.
Anybody is interested to purchase the full package ?
I repeat, well working with original P-Ubuntu for Cluster.
With Heat sink and fan, cables, 4 USB cables for powering each board.
Picture here attached.
Let me know, I could ship everywhere, shipment expenses and customs fees on charge to purchaser.
Best price to be agreed.
Thanks and best regards

Hope you are 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 more 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

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
