Rust and CUDA C++ outperform Triton on irregular GPU workloads

A new research paper compares the performance of CUDA C++, Rust, and Triton for GPU workloads, particularly focusing on irregular operations like hash table insertions. The study found that while all three languages perform similarly on regular, dense linear algebra tasks, Rust and CUDA C++ significantly outperform Triton on irregular workloads. Triton's limitations in expressing probe loops and atomic operations lead to substantial performance degradation and even data loss in certain scenarios. AI

IMPACT Highlights how programming language choice significantly impacts performance on irregular GPU computations, crucial for AI model training and inference.
