Darktable is geared towards using the GPU whenever possible; the CPU is mostly used for "bookkeeping". While it might theoretically be possible to handle multiple images in parallel, it wouldn't get you much (if anything): treating several images in parallel on the GPU cannot be faster than treating them sequentially. In addition, you'd need to have the RAM to deal with multiple images.
