Hi there,

I have a very simple question for you.

I just unpacked my new GTX 690 and I was on the point of starting the preliminary tests on my MATLAB application. Since the algorithm involves very simple arithmetic operations, I managed to obtain a very good speed-up by just using the Parallel Computing Toolbox with “gpuArray” (with my previous card, a GTX 460, I obtained a speed-up of about 40x).

The problem is that the new GTX 690 is a dual graphic card, since there are two coupled GPUs inside it. I thought that MATLAB would anyway see it as a single card, thus avoiding the burden of modify the code in order to manually balance the computing load between the two cards. It does not seem to be the case: MATLAB recognizes it as two separate cards, so I am afraid I will have to change my script and manually distribute and synchronize the computation.

Does anybody have any suggestion on how to use the GTX 690 as a single graphic card with MATLAB Parallel Computing Toolbox??

Since the card is quite new, I didn’t found anything interesting on the web…

Thank you guys!

Cheers,

Alberto
