again, as I said, you develop and propose a patch to the ublas
mailing-list. We're happy to see contributions from anybody.

Now I must say that we are interested in Neon instructions for ublas.
It has been on the todo list for quite a long time too:
http://ublas.sf.net

What I want to say is, apart from the 2 GSOC students and myself
(general maintenance, official releases), nobody has a specific task
assigned to.

So if you want to contribute, you just work on it and talk about it on
the mailing list so that people can be involved and help you.

If little by little you contribute with amazing ARM Neon code, then
people will naturally take for granted that you are the ARM Neon
specialist for ublas. As simple as that.

If someone comes with a better code than you then we will choose the
other code. If you come with a better code than someone else, then we
will choose your code.

So please, contribute.

Are you testing your code on a specific machine or a virtual one ?
What's about things like Raspberry Pi ? I'd like to see benchmark on
this little things. Maybe you can start benchmarking ublas on a tiny
machine like that and/or an Android device and see how gcc is able to
generate auto-vectorized code for this machine. Check the assembly
code to see if Neon instructions have been correctly generated.

Best,
David
