DSL Design Principles#
Abstraction Level
- High enough for ML practitioners to use effectively
- Low enough to enable hardware-specific optimizations
- Familiar syntax and semantics for target audience
- Composable and modular design
Performance Optimization
- Automatic kernel fusion and optimization
- Memory access pattern optimization
- Hardware-specific code generation
- Runtime adaptation and tuning
Developer Experience
- Debugging and profiling tools
- Integration with existing ML workflows
- Clear error messages and documentation
- Gradual learning curve
Helion DSL Deep Dive#
Architecture Overview:#
- Python-embedded DSL for ML kernel authoring
- Compiles to Triton for GPU execution
- PyTorch-like syntax for familiarity
- Ahead-of-time autotuning engine
Key Features:#
# Helion DSL example
import helion
@helion.kernel
def matmul_kernel(a, b, c, M, N, K):
# PyTorch-like syntax
for i in helion.grid(M):
for j in helion.grid(N):
acc = 0.0
for k in range(K):
acc += a[i, k] * b[k, j]
c[i, j] = acc
Autotuning Engine:#
- Automatic search space exploration
- Performance model-guided optimization
- Hardware-specific parameter tuning
- Caching of optimal configurations
