How to run two programs simultaneously

Hello everyone, everything good?

Would it be possible to run two machining programs simultaneously within Linux CNC?

I have a lathe with 2 spindles, each spindle has its respective X and Z.

So I can work with simultaneous cycles at the same time.

Thanks

This is currently not possible.
If you are experimental you could try running two PCs with LinuxCNC on each and then think of a way to control gcode execution of one PC with the other.

Do you know if anyone has tried this?

Would it be very difficult to make this modification in Linux?

My objective would be to control a machine with 6 spindles

a machine like this:

Well, now you have gone from a lathe with 2 spindles to a machine with 6 in two posts.

I don't know of any reports on using more than one instance of LinuxCNC, so it would be experimental even for 2 spindles let alone for 6.

Yes. I know of someone who've accomplished a dual-workstation synchronized motion controller. One of them servicing gcode and acting as a "wait-server" and the other servicing gcode only. Wasn't made with linuxcnc, however the same can be achieved given a significant amount of passion. 

Synchronized channels are only possible if post-processed as such. Often using a "wait cycle" or M function for the sync flag, hence the wait-server required to sync both workstations in the context of what member Aciera rightly advised already. You'll also need to acquire a CAM that is adapted for a multi channel machine-tool -the like showcased in your video.
