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 On Wed, May 29, 2013 at 8:50 AM, Aditya Avinash wrote:

Thank you! Can i develop a new kernel for uBLAS using NEON?

Hi, i want to develop boost.arm or boost.neon library so that boost is implemented on ARM.

Hi,

Boost works well on arm, so nothing should be really developed. But if you ate talking about SIMD for ARM, that you shall take a look at Boost.SIMD and maybe propose library developer your help.

Even if it's not openly provided by developers of NT2, nothing prevents you from implementing it yourself.

yes and no ... if the nt2 devs submit boost.simd to become an official part of boost, it is the question if they'd merge an independently developed arm/neon support, if it conflicts with their business interests ... the situation is a bit unfortunate ... tim

According to https://www.lri.fr/~falcou/pub/pact-2012.pdf .In the last page, they have mentioned about extending boost to SIMD enabled ARM processors. ---------------- Atluri Aditya Avinash, India.
