Bend is a revolutionary high-level, massively parallel programming language that combines the simplicity of Python with the power of functional programming, enabling effortless parallelization and unprecedented performance.
บทคัดย่อ
The article introduces Bend, a new programming language that aims to revolutionize parallel programming. Bend is described as a high-level, massively parallel language that feels like Python but scales like CUDA, running on both CPUs and GPUs.
The key highlights of Bend include:
- Automatic parallelization: Bend automatically utilizes thousands of threads to parallelize code, as long as the code is not "helplessly sequential".
- Embracing immutability and functional programming: Bend's design focuses on immutability and functional programming principles, making it easier to write correct and efficient parallel code compared to traditional parallel programming approaches.
- Simplicity and expressiveness: Bend combines the simplicity and ease of use of Python with the power of languages like Haskell, allowing developers to write concise and expressive code that can still run at high speeds.
The article provides a brief "Hello World" example in Bend, showcasing its syntax and parallel tree-building capabilities. It then highlights the impressive performance of Bend, demonstrating significant speedups over single-threaded execution, up to 181x on an NVIDIA RTX 4090 GPU.
The article concludes by discussing the future plans for Bend, including the addition of immutable textures, which could enable the development of entire game engines in this Python-like parallel programming language. The author encourages readers to join the Bend community on Discord and be part of the revolution in parallel programming.

On an Apple M3 Max with a single thread, a simple parallel sum took 147 seconds.
On the same Apple M3 Max machine with 16 threads, the same parallel sum took only 8.49 seconds, a speedup of 18x.
On an NVIDIA RTX 4090 with 16,000 threads, the same parallel sum took only 0.82 seconds, a speedup of 181x over the single-threaded version.
