Andrew,
Out of curiosity, what would you hope to offload to the other
cores? How do they communicate? Would you be looking for
Mosquitto/MQTT to be a pub/sub solution between the cores, or as a
gateway to send messages off chip to a server?

Hi Andrew,
I really wanted to do some reading around parallela before
replying - that's not happened though. I can say for certain
that they look like very neat boards. Definitely the kind of
thing you itch to have but without necessarily having a plan of
what to use it for.
At the moment the mosquitto broker is entirely single threaded,
so it's perhaps difficult to see the advantage for the broker on
its own, but you could run other application level or support
software on the same board... Not very exciting perhaps.
Looking at threading for the broker is something it would be
good to do - perhaps for 2.0 though. I dare say using that many
cores effectively would be quite a challenge.

Hello,
Firstly, by way of an introduction, I'm community manager for
the
Parallella project [1].
Earlier this year at FOSDEM I met with Mike Millinkovich and
we
briefly discussed the idea of running mosquitto on the
Parallella
computer. Since then a demo was put together [2], but just
making use
of the ARM host and not Parallella's 16-core floating-point
accelerator.
So, I wondered if anyone might be able to comment on whether
mosquitto
and Parallella could be a good match, using the Epiphany chip
to
offload certain operations. The hope being that given the
Parallella/Epiphany architecture [3] and that mosquitto
brokers many
small messages, the combination of the two may be able to
yield some
interesting performance figures.
Thoughts?
Regards,
Andrew
