why does multiple gpu not work?

[Shyam Prasad V Atri]

I have a tank which has these dimensions

x [-0.7,0.7]

y[-0.5 0.5]

z[-0.5 0.5]

I am trying to run the simulation with 4gpu and i keep getting error in the simulation. This error is so generic and i dont know why it is causing

Error:QSocketNotifier: Can only be used with threads started with QThread

I have given the correct gpu slicing --multi-gpu-slicing-direction=X but still i get this error

Can anyone suggest why?
