Setting Up Environment Variables

Understanding CUDA Environment Variables

Environment variables tell your system where to find CUDA binaries and libraries. The PATH variable enables command-line access to CUDA tools like nvcc (NVIDIA CUDA Compiler).

LD_LIBRARY_PATH helps the system locate CUDA runtime libraries during program execution. Incorrect library paths cause “library not found” errors when running CUDA applications.

CUDA_HOME provides a standard reference point for build systems and development tools. Many compilation scripts and makefiles rely on this variable to locate CUDA installations.

Permanent Environment Configuration

Edit your shell configuration file to add CUDA paths:

nano ~/.bashrc

Add the following lines at the end of the file:

export PATH=/usr/local/cuda-12.2/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-12.2/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export CUDA_HOME=/usr/local/cuda-12.2

Adjust the version number (12.2) to match your installed CUDA version. Save the file and exit the editor.

Apply the changes to your current session:

source ~/.bashrc

For system-wide configuration affecting all users, add these variables to /etc/environment:

sudo nano /etc/environment

System-wide configuration requires administrative privileges and affects all user accounts on the system.

Verification of Environment Setup

Test PATH configuration by checking nvcc accessibility:

which nvcc

Successful output shows the path to the CUDA compiler, typically /usr/local/cuda-12.2/bin/nvcc.

nano test_cuda.cu

Add basic CUDA code:

#include <stdio.h>

__global__ void hello() {
    printf("Hello from GPU!\n");
}

int main() {
    hello<<<1,1>>>();
    cudaDeviceSynchronize();
    return 0;
}

Compile and run the test program:

nvcc -o test_cuda test_cuda.cu
./test_cuda

Successful execution prints “Hello from GPU!” confirming end-to-end CUDA functionality.

lsmod | grep nvidia

If no output appears, manually load the driver:

sudo modprobe nvidia

For persistent loading issues, check secure boot settings. Disable secure boot in BIOS/UEFI settings, as it can prevent unsigned kernel modules from loading.

Display manager conflicts during installation

Switch to a text terminal (Ctrl+Alt+F1) before driver installation. Stop the display manager:

sudo service lightdm stop

Complete the installation in text mode, then restart the display manager:

sudo service lightdm start

Kernel module compilation failures

Ensure kernel headers match your running kernel:

sudo apt install linux-headers-$(uname -r)

Mismatched headers prevent proper kernel module compilation during driver installation.

CUDA Toolkit Issues

“nvcc: command not found”

This indicates PATH configuration problems. Verify CUDA installation directory:

ls -la /usr/local/cuda*

Add the correct path to your shell configuration:

echo 'export PATH=/usr/local/cuda/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

Library linking errors during compilation

Set LD_LIBRARY_PATH to include CUDA libraries:

export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

For permanent configuration, add this to ~/.bashrc.

Permission denied errors in CUDA directories

Fix ownership and permissions for CUDA installation:

sudo chown -R root:root /usr/local/cuda*
sudo chmod -R 755 /usr/local/cuda*

Performance and Runtime Issues

GPU not detected by CUDA applications

Verify GPU visibility to CUDA:

nvidia-smi
nvidia-smi -L

Check that your application uses the correct GPU if multiple cards are installed. Set CUDA_VISIBLE_DEVICES environment variable to specify GPU selection.

Out of memory errors during execution

Monitor GPU memory usage:

nvidia-smi --query-gpu=memory.used,memory.total --format=csv

Reduce batch sizes or model complexity to fit available GPU memory. Consider using gradient checkpointing or mixed precision training to reduce memory requirements.

Poor performance compared to expectations

Check GPU utilization during workload execution:

nvidia-smi dmon

Low utilization may indicate CPU bottlenecks, insufficient data loading speed, or suboptimal algorithm implementation.
