Benchmarking A\b on the GPU runs on CPU in parallel?

Asked by Ivan
on 19 May 2013
Hi,
I want to ask if the this benchmark: http://www.mathworks.com/products/parallel-computing/examples.html?file=/products/demos/shipping/distcomp/paralleldemo_gpu_backslash.html runs on the CPU in parallel or sequentially. I have Intel Xeon L5640 with 12 cores and i want to now if the benchmark runs on all cores or just 1.
Thanks for answer.

The CPU portion of this benchmark is multithreaded, so you should see more than one core working during the linear system solve.
