Documentation

There are a number of resources available to learn how to write programs with ispc.

To get started with the language, there is a walkthrough of a simple program written in ispc that highlights some of the main features and language constructs.

After reading the example, see the User's Guide, which provides a complete reference to the language and standard library, and ISPC for Gen user’s guide for additional information about GPU support. You may also find that the Performance Guide provides useful information about getting best results from the system.

The examples/ directory of the ispc distribution has approximately ten examples of using the language to accelerate various computations. All of these have reference serial C++ implementations, which makes it easy to compare the differences between ispc and C++ implementations of various algorithms. (You can also browse this code directly on github.)

A technical paper on ispc, ispc: A SPMD Compiler for High-Performance CPU Programming, by Matt Pharr and William R. Mark, has been accepted to the InPar 2012 conference. This paper describes a number of the design features and key characteristics of the ispc implementation.

Finally, there is a growing list of frequently asked questions (FAQs).
