PIX4Dmapper cannot distribute processing over multiple computers. However, it is optimized to take advantage of multi-Cores and multi-Processors. You can find more information here: https://support.pix4d.com/hc/en-us/articles/202556809-macOS-Windows-XP-Linux-Remote-access-Parallel-processing

If this is the case, PIX4Dmapper is not creating this kind of output (also, it will not be possible to create these images for images at the border of the project). If you need an orthoimage of a region smaller than the entire project, you can use the Processing area feature in PIX4Dmapper as described here:
