To learn more please visit the C++ AMP blog, and we encourage C++ AMP questions in the Parallel Computing in C++ and Native Code MSDN forum. en Thu, 23 May 2013 20:45:51 GMT Thu, 23 May 2013 20:45:51 GMT Rev9 Re: Matrix Multiplication with C++ AMP Awesome Smiley  Tnx a lot for this videocast...

Thank you for this video lecture.

You should have showed the time it takes for each version at the end....
Now I have to write the code and try it. :)

Thanks!

@Elad:Thanks, glad you found it interesting. Yes I leave the time measurement to you so you can explore the benefits on your specific hardware Wink

I'm relatively new to AMP. comparing with what i know from using sse intrinsics for example (not really comparable, i know, but some concepts are at least similar) i'd expect some code for dealing with odd length vectors i.e. padding or computing the rest in a non-tiled way (painful). did i miss something here? im sure i did..

cheers!
