Running Remotely

Requirements:

• Make sure your system has Python 3.7 or greater.

• Make sure MCS has been installed per the install instructions

To run MCS on a remote GPU server, use the following steps to launch an X11 server.

# Update and install dependencies
$ sudo apt-get install xserver-xorg
$ sudo apt-get install xorg
$ sudo apt-get install nvidia-driver-470
$ sudo apt-get install glxinfo

# Identify your machine's GPU BusID
$ nvidia-xconfig --query-gpu-info
GPU #0:
Name      : Tesla K80
UUID      : GPU-d03a3d49-0641-40c9-30f2-5c3e4bdad498
PCI BusID : PCI:0:30:0

# Create the Xserver configuration using the BusID
# Your virtual display size should be much larger than the MCS Unity window size (default 600x400)
$ sudo nvidia-xconfig --use-display-device=None --virtual=1200x800 --output-xconfig=/etc/X11/xorg.conf --busid=PCI:0:30:0

# Launch Xserver
$ sudo /usr/bin/Xorg :0 &

# Test the display setting using glxinfo
$ DISPLAY=:0 glxinfo
name of display: :0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4

Remote Cache Addressables Script

# Activate your python virtual environment
$ DISPLAY=:0 cache_addressables

Remote Runs on AWS

The following code was run on an AWS p2-xlarge with the Ubuntu Deep Learning AMI.

# Follow the instructions listed above to launch Xserver
$ sudo nvidia-xconfig --use-display-device=None --virtual=1200x800 --output-xconfig=/etc/X11/xorg.conf --busid=PCI:0:30:0
$ sudo /usr/bin/Xorg :0 &

# Download the MCS repository
$ git clone https://github.com/NextCenturyCorporation/MCS.git
$ cd MCS

# Install and activate a new python virtual environment
$ sudo apt-get install python3-venv
$ sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1
$ python -m venv venv
$ . venv/bin/activate

# Install the python dependencies
$ pip install --upgrade pip setuptools wheel
$ python -m pip install -r requirements.txt
$ python -m pip install -e .

# Do a test run
