existing 16core chips

so one problem, it seems, is although the architecture is scalable, it's difficult to scale software -
e.g. if you write and tune something for a 16 core 512k chip , the decisions might be quite different compared to the 1024core, 64mb chip, where you can fit a much more interesting problem directly in the scratchpads; and similarly, although there are clusters out there, they use message passing / networks, whereas the epiphany uses PGAS.

Would the world be interested in using some of the remaining parallela chips to build a grid, made available online for testing and tuning code much more similar in shape to what the Epiphany-5 could handle. (e.g. imagine if there was a 32x16 x 16core,64mb grid sat online with some web interface)

.. I guess that would still mean designing and building an entirely new board, so maybe this is just as much of a pipedream as even getting the 1024 core chip.. and if you could get any funding together you might as well dive in with that

Sounds like the meta module might be helpful (which I posted about a few days ago, but probably got lost in the spam.) https://github.com/parallella/parallell ... aster/meta which would be 256 Epiphany III cores. On http://www.adapteva.com/andreas-blog/adapteva-status/ it says that this has been manufactured too, not sure what volume though (I guess small numbers.)

There are open source projects coming from the scientific community for scaling your software for multi-core High Performance Computing. I don't recall the name of any right now, but I know places like Oak Ridge National Laboratory uses it, and even had a contest this year for groups to present applications for a chance to run it on their Titan. Because of the contest, they presented numerous webinars with the NCSA this past summer on development on super computers. I think the people using Blue Waters super computer is doing the same.

You may want to check out their web site for these webinars, and the software for scaling your application.

Update: Found one of the webinars (Video available on YouTube)
