Lovely board, lots of potential - but no community because it's hard<br>
to program the fast cores - lots of low level C programming to make<br>
best use of it, though someone did do a GNURadio port for Google<br>
Summer of Code a while back<br>
<br>
I was a Kickstarter backer - but chickened out of the significant<br>
porting effort needed. The orignal Kickstarter board came without<br>
significant heatsinking so needed extra fan cooling. There was<br>
an Ubuntu port for it - and it would probably run Debian with no<br>
huge problem - armhf.<br>
<br>
It's an ARM, FPGA and then however many Epiphany cores - Anders<br>
Olofssen (? spelling ?) built his ideal system for signal<br>
processing tasks because he couldn't find the necessary for his<br>
Ph.D - the paraphrase on lack of community is from his site.<br>
<br>
Ericsson and others have, however, funded additional R&D so<br>
they've got to 1024 core boards. Really useful for a compact<br>
supercomputer / specialist 5G hardware but fairly tough<br>
for pretty much everybody else to get a toehold because the<br>
initial learning curve is non-trivial.<br>
