MATLAB built for Speed: Jacket SGEMM tops 700 GFLOPS on the GPU

I'm kind of surprised that MathWorks hasn't acquired Accelereyes yet. It seems to me that Jacket would be a great thing to either integrate into the core of MATLAB, boosting MATLAB's competitiveness with other tools such as IDL and Maple, or to sell as one of the many add-on toolboxes, leveraging their long-standing relationship with academia to build mindshare among young engineers.

Jacket is incredibly impressive. However, since I started using it I’ve noticed that I’ve spent more time benchmarking than I have doing math! Furthermore, I suspect it’s prohibitively expensive for most. However, GPUmat (<a href="http://www.gp-you.org" rel="nofollow">http://www.gp-you.org</a>) is a notable free alternative.

@Q6T56nT668w613m<p>That is what you get when you have a shiny new toy you can not get your hands off ;)<p>As for it being prohibitively expensive, it is competitive (and sometimes a lot cheaper) than the equivalent matlab toolboxes.
