An open-source compiler for high-performance SIMD programming on CPU and GPU

ispc is a compiler for a variant of the C programming language, with extensions for "single program, multiple data" (SPMD) programming. Under the SPMD model, the programmer writes a program that generally appears to be a regular serial program, though the execution model is actually that a number of program instances execute in parallel on the hardware. (See the ispc documentation for more details and examples that illustrate this concept.)

Features

• High Performance: Optimized for SIMD programming, ensuring efficient parallel execution.
• Open Source: Freely available for modification and distribution.
• SPMD Model: Simplifies parallel programming with a familiar serial programming model.
• CPU and GPU Support: Compatible with both CPU and GPU architectures.
• Extensible: Easily integrates with existing C codebases and development workflows.
