Talk Teaser: Image processing with Mono.Simd

The facts:

Processing time using gdk_pixbuf: 431ms
Same method ported to Mono.Simd: 66ms
That means roughly 6.5 times faster !

Some explanations:

• The gdk-pixbuf is an unoptimized standard gdk operation (gtk+ 2.18.1), but I don't think a lot of them are optimized either using mmx or SSEx for this platform (x86-64). Feel free to prove me wrong here.
• Times are averaged.
• Loading and saving times aren't taken into account here, but both are using gdk_pixbuf operations.
• The Mono.Simd method acts on vanilla pixbufs, and results are plain old usable pixbufs, not some kind of memory buffer or whatnot.
  
• The image attached to this post is not the result of the processing.

This is only a teaser for the short talk I'll be giving at FOSDEM on Sunday Feb 7. Be there if you want to learn more, see the code, or question my sanity for doing this in Mono and not directly as a gdk-pixbuf patch.

Mono devroom @ FOSDEM 2010

Mono got a room at FOSDEM2010 in Brussels, so we won't have to do that in the hallway this year !

Want to speak about something fun you did with mono ? Propose a talk. Using mono on your servers saved your company from bankrupt in 200[89] ? Talk about it too. You are a passionate mono hacker and want to spread the word about what we'll got in the upcoming version ? You know the link.

And for everyone else, eager to learn about it, to discuss it, join on Sunday Feb 7. You're all welcome.

Note: be quick, the deadline for the cfp is around Dec 20.
