GPU calculation : step 3

For running the benchmarks, I will use the Jacket plugin for Matlab. Jacket is a Matlab add-on which provide easy-to-use GPU enabled functions.

After running the tests, the results are not those expected, the GPU calculation is slower than the CPU calculation. After discussion with the Jacket customer support, it appears that our GPU (an nVidia Quadro 2000D) is not powerful enough.

Hopefully the University of Oxford just allows me to use one of their supercomputers. This computer called 'Skynet' is equipped with 4 nVidia Tesla C2020 GPUs.
