[ANN] A blog post about using NMatrix to achieve a 400x boost on matrix multiplication

[Abinoam Praxedes Marques Junior]

Hi all,

I've just made a small blog post with a benchmark of NMatrix#dot.
I hope you enjoy!

Hi Abionam,

Nice work!

In the code I see 200 and 800 elements. You should try with more no. of elements.

Also, if you try using nmatrix-atlas instead of nmatrix, you go 8000x faster.

Regards,

Prasun

Hi Prasun,

I'm really a newcomer on this field! I just was amazed how NMatrix can be helpful.
So, don't understand much about ATLAS, etc.

But, 8000x!?! I'll have to try it!

Thanks for the feedback.
I wrote the blog post so more Ruby devs get to know NMatrix and SciRuby.

Best regards,
Abinoam Jr.

And then we'll be adding GPU support this summer...

[Prasun Anand]

Yes. NMatrix is indeed helpful.  I guess you can make more tweaks.

SciRuby appreciates your effort. Its a good first try ;) .

Prasun
