@gdkrmr Thanks for reporting this. Unfortunately, I have no clue of what is going on here. Does locking the screen also involve potentially putting the computer into sleep? Maybe you could try to ctrl C the julia process and see if it produce any meaningful stack traces.
no, the computer does not go to sleep, the screens get turned off though.
When I interrupted the process later with ctrl-c it was in some cublas
call, but I am not sure if this was just by coincidence. Because of that
issue I finally changed the setup of my graphic cards and now I can lock
the screen without problems. I use bumblebee
now and run my script
with optirun julia myscript.jl
. In general I used to have a lot of
problems with my computer freezing because of the power management of
the nvidia card but since I got bumblebee
to work the nvidia card
is only used when it is needed.
There is one thing that I observed: When I start a process with
optirun
and finish it later the gpu does not get turned off until
I lock my screen.
I doubt that you can fix the problem at Mocha
-level, but some
error message would help.

Closing for now as it seems not possible to fix from our side.
I have the following Issue using the GPU backend:
I am trying the
denoising-autoencoder.jl
example (I changed two lines to make it use the gpu backend) and it seems to work fine. But when I lock my screen, and get back, the julia process will keep consuming 100% cpu without producing any output and the gpu is idle.I am on a laptop with a nvidia 840m and ubuntu 14.04. I did a quick test with Theano and it seemed to work fine, that is why I am posting here.
There are some unresolved issues with the power management and the gpu which probably break some internals and cause my computer to freeze sometimes.
I am posting here, because Theano seems to work fine. If the problem is really the linux/nvidia driver interaction, it would be nice to get an error at least.
