stereo_tir running slowly #322

I try to run the data processing example for HiRISE in asp_book 11.2. The stage triangulation spends more than 20 hours, but other stage only spend 2 hours in total.

Skip step of cam2map4stereo.py, the time spend by triangulation is greatly reduced.

Is there something wrong with the application build by myself?

Thank you.

You should use parallel_stereo instead of stereo. I updated this in the doc at that location and many related places. Thanks for pointing this out.

The reason this takes so long is because the triangulation step is single-threaded, unlike the other ones, which is something we inherited from ISIS.

BTW, you can also run stereo from stereo_gui, which will allow one to select some clips on which to run things, if desired to get a quick result.
