Shell Commands for the GPU Server¶
The following is a list of shell commands for the AI Racing League GPU Server. We have moved all the commands for setting up the NVIDIA GPU to the file NVIDIA Driver Install.
The samples below are run if you are on the GPU running the Terminal shell or you have logged on using the secure shell program.
Secure Shell Login¶
$ ssh arl@arl1.local

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¶
free -m
Response:
total used free shared buff/cache available
Mem: 32124 1627 28879 75 1618 30019
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¶
df -h /
Response:
Filesystem Size Used Avail Use% Mounted on
/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¶
du -hs /home/* 2>/dev/null
Response:
8.5G /home/arl
1.4G /home/dan
16K /home/dan2
155G /home/donkey
Add A New GPU Server User¶
adduser donkey
sudo usermod -aG sudo donkey
Change the Hostname¶
sudo vi /etc/hostname
Change the name to "gpu-server2" or a similar name.
GPU Commands¶
Display Type¶
sudo lshw -class display
Response:

This display is difficult to read. But the key item is in the second column under the Memory-Usage area:
184MiB / 11018MiB
This says that we are using 184 megabytes and have 11.018 Gigabyte to use to run our machine learning tasks.
NVIDIA GPU Monitor¶
The runs similar to the UNIX top command, but for the GPU.
watch -d -n 0.5 nvidia-smi
NVIDIA GPU Utilization¶
This shows the GPU running at 42% utilization during the training process.
