These utilities help identify bottlenecks. They ensure your training runs efficiently. Real-time monitoring allows quick adjustments. This prevents crashes and optimizes performance.

# Install htop if not already present
sudo apt install htop
# Run htop to monitor CPU, memory, and processes
htop
# Monitor NVIDIA GPU usage in real-time (updates every 1 second)
watch -n 1 nvidia-smi

htop shows CPU core usage, memory consumption, and running processes. You can sort by various metrics. nvidia-smi displays GPU utilization, memory usage, and temperature. This is crucial for deep learning tasks. These essential Linux tools give you full visibility into your system’s health. They are vital for resource-intensive AI workloads.

Remote Access and File Transfer

AI development often involves remote servers or cloud instances. Secure Shell (ssh) is the standard for remote access. It provides an encrypted connection. Secure Copy (scp) transfers files between local and remote machines. These tools are fundamental for managing remote AI infrastructure. They enable seamless interaction with distant compute resources. You can execute commands and manage files remotely.

# Connect to a remote server
ssh username@remote_server_ip
# Copy a local file to a remote server
scp /path/to/local/model.pth username@remote_server_ip:/path/to/remote/destination/
# Copy a directory from a remote server to your local machine
scp -r username@remote_server_ip:/path/to/remote/data/ /path/to/local/destination/

ssh allows you to run commands as if you were locally present. scp handles secure file transfers. The -r flag is for recursive directory copies. These essential Linux tools are indispensable for distributed AI development. They simplify working with remote GPUs or data storage.
