On the GUI

Created page with " The GPUs accessible by your system in an interactive session (i.e., assuming you can directly ssh onto the node where the GPUs are installed) can be shown with {{t|nvidia-smi..."

New page

The GPUs accessible by your system in an interactive session (i.e., assuming you can directly ssh onto the node where the GPUs are installed) can be shown with {{t|nvidia-smi}}.

Remember that some GPUs are dual devices. A single NIVIDIA K80 will show as two different devices, with two different integer numbers.

==Setting the identifiers==

You need to make certain that the identifiers that you pass to the project are correct. During unfolding, ''Dynamo''will not check that the device numbers are correct!

=== On the GUI===

In the [[dcp GUI]] go to the [[computing environment GUI]]. In the GPU panel there is an edit field for the gpu identifiers.

===Through the command line==-

The parameter is called {{t|gpu_identifier_set}} (short {{t|gpus}}). You can set it into a project using {{t|dvput}}, for instance:

<tt>dvput myProject gpus [0,1,2,3]</tt>

==Environment variable==
In some rare systems, you might to be required to manually set the environment variable {{t|CUDA_VISIBLE_DEVICES}} to the device numbers that you already selected inside ''Dynamo''.
