Course content

1 section5 lectures34m total length
  • Introduction0:28
  • PyTorch Softmax7:14

    Explore a naive softmax in pytorch, including exponentiation, max-subtraction, and normalization, and learn why op fusion is key for gpu performance with triton on colab.

  • Writing the Triton Kernel7:41

    Learn to implement a Triton kernel by managing input and output pointers, strides, and block sizes, using on-chip memory and masking, exponentiation, and dividing by the sum, writing to HBM.

  • Preparing the Kernel for Execution12:16

    Prepare the kernel for execution by configuring the device and querying streaming multiprocessors, registers, and shared memory, then compute occupancy to optimize kernel launches via Triton IR to CUDA binary.

  • Running the Kernel and Comparing to PyTorch6:52

    Run a softmax kernel and compare its results to PyTorch's naive softmax to verify numerical accuracy and understand floating-point tolerance in GPU scripting.

Requirements

  • Experience in machine learning and PyTorch.

Description

Unlock the power of GPU acceleration without writing CUDA code! This hands-on course guides you through creating custom high-performance kernels using Triton and PyTorch on Google Colab's T4 GPUs. Perfect for ML engineers and researchers who want to optimize their deep learning models.

You'll start with Triton fundamentals and progressively build toward implementing an efficient fused softmax kernel - a critical component in transformer models. Through detailed comparisons with PyTorch's native implementation, you'll gain insights into performance optimization principles and practical acceleration techniques.

This comprehensive course covers:

  • Triton programming model and core concepts

  • Modern GPU architecture fundamentals and memory hierarchy

  • PyTorch integration techniques and performance baselines

  • Step-by-step implementation of softmax in both PyTorch and Triton

  • Deep dive into the Triton compiler and its optimization passes

  • Memory access patterns and tiling strategies for maximum throughput

  • Register, shared memory, and L1/L2 cache utilization techniques

  • Performance profiling and bottleneck identification

  • Advanced optimization strategies for real-world deployment

  • Hands-on practice with Google Colab T4 GPUs

You'll not just learn to write kernels, but understand the underlying hardware interactions that make them fast. By comparing PyTorch's native operations with our custom Triton implementations, you'll develop intuition for when and how to optimize critical code paths in your own projects.

No CUDA experience required - just Python and basic PyTorch knowledge. Join now to add hardware acceleration skills to your deep learning toolkit and take your models to the next level of performance!

Who this course is for:

  • Machine learning developers who wish to author their own kernels.
