[Boost.SIMD] Interest in library
Hi, I'm interested in trying out Boost.SIMD. Where can I download the latest stable version? Any idea when it might get proposed for Boost review? I think it would be beneficial if it is added to the Boost Incubator until then. Also, in http://meetingcpp.com/tl_files/mcpp/slides/12/simd.pdf slide 36 I see mention of a vectorized Thomas Tri-diagonal Solver. I thought the data dependency made the algorithm unfeasible for vectorization, so I'm *very* interested to learn how Boost.SIMD helps in this case. Is there more information available about this? Thanks for working in a library that shows a lot of potential.

Latest stable version is 3.1.0, that you can download at <http://nt2.numscale.com/downloads/> Documentation is here: <http://nt2.numscale.com/doc/html/boost_simd.html>

We're working on improving compilation times, which requires some important redesign of the library. The library will be submitted for review after that. It's been going on for the past few months, but those efforts are finally coming to an end! Expect something soon-ish.

You can try looking at the paper on this topic, "A Parallel Solver for Incompressible Fluid Flows" by Yushan Wang. Hopefully Joel Falcou, who also worked on this project and also browses this mailing list, can tell you more about this.

Thanks for the info!

Do you know if it will support C++03 or will it require C++11?

From that paper: "The SIMD opportunity in our algorithm stands from the fact that solving the tridiagonal systems with multiple RHS can be performed in parallel."
Darn! I only have a single RHS, too bad! Thanks!

Looking forward to this. I remember talks about this library back in 2009! -- Cory Nelson http://int64.org
