===== Learning on GPU Servers =====

There are [[https://cyber.felk.cvut.cz/cs/study/gpu-servers/|GPU servers]] available via remote access (''ssh'').
Log in via one of these commands (use your faculty username):\\
''ssh -X username@cantor.felk.cvut.cz''\\
''ssh -X username@taylor.felk.cvut.cz''\\
Singularity images may also be located under ''/local/singularity_images''.
You can follow, more or less, the [[courses:aro:tutorials:ros#at_labs|instructions for labs]] once you are there.

Also, please read [[https://cyber.felk.cvut.cz/cs/study/gpu-servers/|the instructions]] on GPU usage.
Most notably, use at most one GPU at once.
Select GPU to use via environmental variable ''CUDA_VISIBLE_DEVICES'', e.g.\\
''CUDA_VISIBLE_DEVICES=2 my_command''\\
Prevent using any if you don't need it:\\
''CUDA_VISIBLE_DEVICES= my_command''\\
You can export it to stay in effect for all the following commands:\\
''export CUDA_VISIBLE_DEVICES=2''\\
''my_command''
