Hello guys - hope everybody is safe and health during the days of COVID-19. I have a case with a project running Monte Carlo simulations on standalone dedicated servers by launching a simulation panel consisting of four different displays to control the simulation. We want to do a system checkpoint right before an event occurs on the simulation, about 20 minutes after it started.
I have found that DMTCP doesn't support X-apps by default (https://sourceforge.net/p/dmtcp/mailman/message/35038633/) and followed the example describing the use of XPRA servers to start the sim panel. I have validated dmtcp_launch can run together with the sim as expected, delays and latency involved when interacting with the sim panel but assume due to the work-from-home involved challenges. Terminal 1: $ dmtcp_launch /usr/bin/dbus-launch /usr/bin/xpra --no-daemon --no-mdns --no-pulseaudio start :100 --start-child='./myProgram.exe MyInput.py' Terminal 2: $ xpra attach :100 Problem shows up when I detach from server (Terminal 2) to do the checkpoint then my sim crashes. Am I missing something in the middle or is there an easier way to deal with X-apps and DMTCP? Again, your input and help is greatly appreciated!
