Bend Programming Language
Introduction to Bend
Welcome to the fascinating world of Bend, a high-level, massively parallel programming language designed to make parallel programming both approachable and efficient. In this guide, we’ll explore the ins and outs of Bend, from its basic syntax and constructs to its advanced features that allow you to harness the power of parallel hardware like GPUs.
What is Bend?
Bend is a programming language unlike any other. Built on top of Rust, it carries the ambition of making parallel programming not just possible but inherently simple. Bend achieves this by removing the traditional barriers associated with parallel programming—such as thread management and explicit synchronization primitives—and instead, promises that “Everything that can run in parallel, will run in parallel.”
This promise is rooted in Bend’s design philosophy, which combines the expressive power of languages like Python and Haskell with the performance capabilities of low-level languages like CUDA. Whether you’re managing fast object allocations, utilizing higher-order functions, or dealing with recursion, Bend handles the complexity behind the scenes, allowing you to write code that scales almost linearly with the number of cores available.
Why Bend?
The world of computing is increasingly moving towards parallelism, with modern CPUs and GPUs offering more cores than ever before. However, traditional programming languages often require developers to manually manage the complexities of parallel execution. Bend is here to change that narrative:
Simplicity in Design: Write high-level code without worrying about the low-level details of parallel execution.
Performance: Bend’s programs are designed to run on multi-core and many-core architectures, squeezing out nearly every bit of performance from the hardware.
Safety: Powered by Rust, Bend inherits strong safety guarantees, helping to prevent common parallel programming bugs like race conditions.
Open Source: Bend is open source, inviting collaboration and innovation from developers around the world.
