if you're talking about ann_mlp, it seems, that only the rprop method uses multi cores. if you're using standard backprop, more cores, or any kind of tbb/omp/pthread support won't help.

gpu support is an entirely different beast. if the Mat sizes are large enough to justify the upload cost, opencl will be used under the hood (think gemm).
