Features

The Intel® SPMD Program Compiler (ispc) provides a number of key features to developers:

  • 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 the Intel® SSE2, SSE4, AVX, and AVX2 instruction sets.
  • Portability across operating systems: Microsoft Windows, Mac OS X, and Linux are all supported by ispc.
  • Debugging with standard tools: ispc programs can be debugged with standard debuggers. OS X, Linux and Windows are supported (but debugging support on Windows is limitted).
