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 developer 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.
It uses the LLVM Compiler Infrastructure for back-end code generation and optimization.
Features include:
- Familiarity as an extension of the C programming language: ispc supports familiar C syntax and programming idioms, while adding the ability to write SPMD programs.
- High-quality SIMD code generation: the performance of code generated by ispc is often close to that of hand-written intrinsics code.
- Ease of adoption with existing software systems: functions written in ispc directly interoperate with application functions written in C/C++ and with application data structures.
- Portability across over a decade of CPU generations: ispc has targets for SSE2, SSE4, AVX, AVX2, and AVX512.
- Portability across operating systems: Microsoft Windows, macOS, and Linux are all supported.
- Debugging with standard tools: ispc programs can be debugged with standard debuggers.
