Lab Information

Server Info

The lab has a multi-GPU server on campus dedicated to research use called El Capitan.

Logging In

You can log in with your Cal Poly credentials. You need to be on the Cal Poly VPN if you are off campus.


You will want to work on the local storage rather than your home directory which is network storage. Each user has a directory at


Datasets can be stored under



Everything is done through Docker on the server.

To use Docker, you need to create a Dockerfile and store it in a sub-directory. For example, create a textfile at “docker/Dockerfile.” Here is an example Dockerfile for Tensorflow:

FROM tensorflow/tensorflow:latest-gpu-py3
RUN apt-get update ; apt-get install vim git wget -y
RUN pip install --upgrade scikit-image tqdm opencv-python

To build the Dockerfile:

docker build docker -t <tag>

You can choose whatever you want for the tag.

To start Docker:

docker run -u $(id -u):$(id -g) --rm --gpus=1 -it -v /data:/data -v /data2:/data2 -e USER=$USER -e HOME=/data/$USER -w $PWD <tag> bash


You can run Docker sessions inside of “tmux”. Use ctl-b ctl-d to leave tmux and “tmux attach” to get back into it. You can finds lots other keyboard commands for tmux.
