TDA4VM: In Pc emulation mode, run the stereo and DOF application simulataneously.

hi,

We have not really tried running two applications simultaneously in host emulation mode, so could you help us with the requirement here? Why do want to run them together?

We want run them in Emulation mode in parallel. This will save us a lot of time while running the sample scenes for evaluation. Is there any way to run them in parallel? 

Hi,

From the above error, it seems it has run out of memory while allocating memory for user data object. Let me check with the team if we can somehow allocate this memory.

Thanks a lot. 

Hi,

May I know which SDK version are you trying this on? I could try to reproduce the same at my end on the same SDK version.

Hi,

I tested this on SDK 8.6 and i was able to run ./vx_app_sfm and ./vx_app_dense_optical_flow in parallel on PC emulation.

Could you please share the exact steps that you are following for exectution?

Did parallel execution work with SDK 8.6?

SDK: rtos-j721e-evm-08_04_00_02

After the setup, try to run app_dof in a infinite loop. While the app_dof is looping, try running app_stereo. That will produce the above error. So, it looks like app_stereo can't run while app_dof is still running. 

You also get seg fault on the first program, when you try running two instances  paralllelly.

Sorry, what you mean by running in infinite loop? You should just start Dof application and let it run..

Did not get it. Are you also seeing seg fault?
