Hello everyone, I'm a french student preparing a Master in Computer Science. I'm highly interested in participating in the 2011 GSoC with Boost. I'm particulary keen on working on the boost.simd subject. I think having SIMD abstraction in boost could be really beneficial (the first example which comes to mind is boost.math). However I have some questions about the subject in order to do my proposal, some of them have already been discussed with Joel Falcou and Mathias Gaunard on IRC, but here it is : One of the main concern I have is that nt2 relies heavily on cmake to detect various things like SSE instruction set support etc. From what I know (I ported nt2 to OpenBSD a while ago), depending on the architecture different methods are used, in order to be portable, like reading from sysctl in OSX or lauching a little executable which collect various informations using cpuid. So the question is : is bjam able to do everything we need to do, or will we need to do the detection in any other way? I use, and I kind of know bjam but I'm not an expert either, I believe Vladimir Prus will be able to help here. Another thing that is a bit blur for me at the moment, is what is the scope of boost.simd? I mean, from what I see the simd part is quite deep-rooted in nt2, has dependencies on several modules of it, so will boost.simd be a subset of nt2 simd module or will we need to rewrite part of it to avoid dragging huge dependencies (and well, end up doing boost.nt2).
