Initial System Preparation

CUDA Installation

Let's start with installing CUDA. Follow these steps carefully:

bash
# Download CUDA 11.8
wget https://developer.download.nvidia.com/compute/cuda/11.8.0/local_installers/cuda_11.8.0_520.61.05_linux.run

# Make the installer executable
chmod +x cuda_11.8.0_520.61.05_linux.run

# Run the installer
sudo ./cuda_11.8.0_520.61.05_linux.run

# Add CUDA to your PATH
echo 'export PATH=/usr/local/cuda-11.8/bin:$PATH' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=/usr/local/cuda-11.8/lib64:$LD_LIBRARY_PATH' >> ~/.bashrc

cuDNN Setup

After downloading cuDNN from NVIDIA's website:

bash
# Extract cuDNN
tar -xvf cudnn-linux-x86_64-8.6.0.163_cuda11-archive.tar.xz

# Copy files to CUDA directory
sudo cp cuda/include/cudnn*.h /usr/local/cuda/include
sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64
sudo chmod a+r /usr/local/cuda/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*

TensorFlow Installation Process

Virtual Environment Setup

Creating a dedicated virtual environment is crucial for managing dependencies:

bash
# Install virtualenv if needed
pip install virtualenv

# Create a new virtual environment
python -m venv tf_core_ultra

# Activate the environment
source tf_core_ultra/bin/activate  # Linux/Mac
.\tf_core_ultra\Scripts\activate   # Windows

Package Installation

GPU Support Configuration

Install TensorFlow with GPU support:

bash
# Install TensorFlow
pip install tensorflow==2.12.0

# Install additional GPU support packages
pip install tensorflow-gpu==2.12.0

Library Dependencies

Install required supporting libraries:

bash
# Install essential packages
pip install numpy scipy pandas matplotlib
pip install keras scikit-learn
pip install core-ultra-sdk==2.5.0

Configuration and Testing

Environment Variables

Set up the necessary environment variables:

bash
# Add to ~/.bashrc or equivalent
export CUDA_HOME=/usr/local/cuda
export PATH=$CUDA_HOME/bin:$PATH
export LD_LIBRARY_PATH=$CUDA_HOME/lib64:$LD_LIBRARY_PATH
export TF_FORCE_GPU_ALLOW_GROWTH=true
export TF_GPU_ALLOCATOR=cuda_malloc_async

Verification Tests

Run these tests to verify your installation:

python
import tensorflow as tf

# Check TensorFlow version
print("TensorFlow version:", tf.__version__)

# Check GPU availability
print("Num GPUs Available: ", len(tf.config.list_physical_devices('GPU')))

# Simple test computation
with tf.device('/GPU:0'):
    a = tf.constant([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
    b = tf.constant([[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]])
    c = tf.matmul(a, b)
    print(c)

Common Issues and Solutions

Installation Troubleshooting

Here are solutions to common installation issues:

1. CUDA Version Mismatch:

bash
# Check CUDA version
nvcc --version

# If needed, create symbolic link
sudo ln -s /usr/local/cuda-11.8 /usr/local/cuda

2. Library Path Issues:

bash
# Add to LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/extras/CUPTI/lib64

Performance Optimization

Optimize your TensorFlow installation:

python
# Configure memory growth
gpus = tf.config.experimental.list_physical_devices('GPU')
for gpu in gpus:
    tf.config.experimental.set_memory_growth(gpu, True)

# Set mixed precision policy
policy = tf.keras.mixed_precision.Policy('mixed_float16')
tf.keras.mixed_precision.set_global_policy(policy)

Advanced Configuration

Multi-GPU Setup

Configure TensorFlow for multiple GPUs:

python
strategy = tf.distribute.MirroredStrategy()
with strategy.scope():
    model = tf.keras.Sequential([
        tf.keras.layers.Dense(64, activation='relu'),
        tf.keras.layers.Dense(10, activation='softmax')
    ])

Custom Build Options

For custom TensorFlow builds:

bash
# Clone TensorFlow repository
git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow

# Configure build
./configure

# Build with bazel
bazel build --config=opt --config=cuda //tensorflow/tools/pip_package:build_pip_package

The Core Ultra 200S platform, when properly configured with TensorFlow, provides a powerful environment for deep learning development. Following this guide ensures you'll have a stable and optimized setup ready for your AI projects.

Frequently Asked Questions

1. Why isn't TensorFlow recognizing my GPU? This usually occurs due to mismatched CUDA versions or incorrect environment variables. Verify your CUDA installation and ensure all paths are correctly set in your environment variables.
2. How can I check if my TensorFlow installation is using the GPU correctly? Run a simple test script that prints tf.config.list_physical_devices('GPU') and performs a basic computation on the GPU to verify both detection and functionality.
3. What's the best way to handle TensorFlow memory issues on Core Ultra 200S? Enable memory growth using tf.config.experimental.set_memory_growth() and consider using mixed precision training to reduce memory usage.
4. Can I use multiple versions of TensorFlow on the same system? Yes, by creating separate virtual environments for each version. Use virtualenv or conda to manage different TensorFlow installations.
5. How do I optimize TensorFlow performance for Core Ultra 200S specifically? Enable XLA optimization, use mixed precision training, and ensure your CUDA compute capability matches your GPU. Also, configure the Core Ultra 200S specific parameters in the SDK settings.
