Parallella Community

Ola has spun up a server with the GCC Explorer tool installed on it supporting Epiphany.
Really fast and quite useful for code optimization.

Thanks for the pointer. I've noticed it produces sensible-looking Epiphany assembly if fed with http://tweetnacl.cr.yp.to/software.html

Publication describing it is here https://cryptojedi.org/papers/tweetnacl-20140917.pdf

I've also successfully built https://github.com/sbp/tweetnacl-tools for ARM. The library is small enough to fit the Epiphany nodes.

While the current cores do not have crypto ISA extensions, I think they would be good crypto accelerators for the power envelope.

Notice that cjdns (which uses cnacl, but tweetnacl should be a drop-in) does build on Parallella for ARM on Paraubuntu if provided with Seccomp_NO=1 ./do.

What is still missing on Paraubuntu is ability to create /dev/net/tun

Apart from that it could be an interesting practical cjdns router, even when not using Zynq FPGA space for switch/crypto implementations.

Ola,

I use http://gcc.parallella.org/ occasionally. If it's not too much trouble, could you add the latest e-gcc. The current version 4.8.2 is a bit dated.
