GUI to control multiple remote hosts (using the same GUI for simulation and real hardware)?

Since you already have a mechanism that works to spawn the processes on the local machine, it sounds like the only thing you're lacking is a way to spawn the processes on the remote machines. I would go with simple ssh connections as it would require the fewest changes to both your infrastructure and your code.

I agree that it seems to be the most straight forward solution, however, it is too low level, and in the future I may need to add more complex interaction,so I want to be sure I'm doing a good choice from the beginning. Thanks – OpenI Oct 5 at 8:08.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
