Speeding up orthorectification

I have hundreds of high-resolution images. I need to orthorectify them. How can I parallize otbcli_OrthoRectification to run in my five computers? Can otbcli OrthoRectification be used with Sparks? Any ideas to speed up the process is welcomed.

You can use MPI writers (currently supported are Geotiff and vrt).
Take a look how the MPIWriters work, to implement your own parallel writer (do not hesitate to contribute :innocent:).
