Harlan is a small domain-specific language implemented in Scheme for programming GPUs, compiled to OpenCL. It serves primarily as a research testbed for exploring compiler analyses and optimization techniques.
Use cases
- write gpu kernels in a high-level dsl
- experiment with compiler optimizations for gpu code
- compile scheme-like programs to opencl
- research testbed for compiler passes
- learn how gpu compilers work internally
When to choose
- you are researching compiler optimization techniques for gpu computing
- you want a small, hackable dsl compiler codebase to study or extend
- you need a scheme-based language that targets OpenCL
When to avoid
- you need a production-ready gpu programming tool with active maintenance
- you want mainstream gpu development with CUDA or OpenCL directly
- you require Windows support or modern OpenCL compatibility
