I recently acquired a GPU, a graphics processing unit. It's called a GPU because such processors were originally intended to speed up graphics. But MATLAB uses it to speed up computation. Let's see how the gpuArray object benchmarks on my machine. I have been doing computer benchmarks for years. I like to do profiles where I vary the size of a task and see how the amount of memory required affects performance. I always learn something unexpected when I do these profiles. Ben Todoroff is on the MathWorks Parallel Processing team. Last year he contributed #34080, gpuBench to the MATLAB Central File Exchange. He has been able to compare several different GPUs. I am going to consider the performance of only one GPU, but in more detail. Important note. This is only about double precision. Single precision is another story. ... read more >>

I am addicted. I keep coming back to John Conway's Game of Life. Years ago, I wrote a chapter about Life in Experiments with MATLAB. I wrote a three-part series about Life shortly after I started blogging. Part 1, Part 2, Part 3. I have recently made significant enhancements to my MATLAB program for Life. I never seem to finish the code because I get diverted by actually using the program to explore the Universe. I invite you to join me. But, fair warning, you might become addicted too.... read more >>
