Bend is an interactive programming environment (REPL) built on top of the Kotlin language, designed to allow users to explore, experiment, and learn Kotlin in a live, feedback-driven manner. The tool lets you define variables, functions, or values at the prompt and iteratively refine them—immediately seeing output and types—while preserving state across commands. It emphasizes discoverability and experimentation: users can inspect functions, call them on sample inputs, and evolve logic without a full project scaffold. Because it’s embedded in a graphical or console interface, Bend aims to reduce the friction of switching between editor and runtime when prototyping or debugging ideas in Kotlin. It can also be extended with libraries or domain-specific tools, making it a flexible playground for domain scripting, education, or data exploration.
Features
- A high-level language that feels like Python to write parallel computation for CPU/GPU without deep expertise in concurrency or CUDA etc
- Automatically parallel execution of work that can be parallelized, with runtime handling threading, task scheduling etc
- HVM runtime: capable of scaling to many threads (hundreds / thousands depending on cores) to achieve near-ideal speedups on multi-core hardware
- Support for both CPU and GPU execution to leverage both types of hardware as available
- Simplified concurrency model: developer doesn’t need to manage low level concurrency primitives (locks etc) manually
- Designed for performance: speedup nearly proportional to available cores / hardware, focusing on efficiency of parallel computations
