MATLAB GPU toolbox: PCT, GPUMat and Jacket revisted

In my last benchmark of the MATLAB GPU toolboxes, I compared PCT from The MathWorks, Jacket from Accelereyes and GPUMat from GPYou. I now updated theses results with new hardware and new some more optimized code. Previously, we used a GeForce GTX 275. Now, we also use the GeForce GTX 520 Ti. On this hardware, […]

Matlab GPU toolbox: Benchmarking Accelereyes vs. MathWorks vs. GP-YOU?

Graphics Card

There is a great option for speed-up of your Matlab code: Use your graphics card. If you have an Nvidia graphics card, there is a whole universe of optimized code for these cards. The underlying technology is called CUDA and many of the required functions for a transparent usage from Matlab already exist. There are […]

The Cost of Redundancy

The Cost of Redundancy Expensive resources spent on computer grids are often wasted. An example from the financial industry teaches how repeated and redundant calculations can eat up all the computing power. Theta Proxy, a simple and yet generic solution, has the potential to save millions in server costs. Nowadays much of the computation time […]
