The key is that we have 12 CPUs and each CPU has two threads. That means that we have 24 threads that run concurrent operations on this server. This is plenty of capacity for our GPU server.

RAM

Swap:          2047           0        2047

This indicates we have 32 GB RAM. The GPU server should have a minimum of 8 GB of RAM.

Disk Space

/dev/nvme0n1p3  229G  178G   40G  82% /

This shows we have a total of 229 gigabytes of RAM and we have 40 gigabytes available. We will need about 4 GB for each training set we store.

Per User Disk Usage

Add A New GPU Server User

1
adduser donkey

You can also allow the user to have "sudo" rights by using the following command:

1
sudo usermod -aG sudo donkey

Change the Hostname

1
sudo vi hostname

Change the name to "gpu-server2" or a similar name.

NVIDIA GPU Monitor

The runs similar to the UNIX top command, but for the GPU.

1
watch -d -n 0.5 nvidia-smi

NVIDIA GPU Utlization

This shows the GPU running at 42% utilization during the training process.
