User and Reference Guide for the Intel® C++ Compiler 15.0

The following are some important features of the compiler:

Getting Started with the Compiler

Getting Started explains how to invoke the compiler on the command line or from within an IDE.

Intel® Cilk™ Plus

Intel® Cilk™ Plus lets you add parallelism to both new and existing programs to efficiently use multiple processors and the vector instructions available on modern CPUs.

Intel® Many Integrated Core Architecture

The Intel compiler supports elements that enable programming for and building binaries to run on the Intel® Many Integrated Core Architecture (Intel® MIC Architecture).

Intel® Graphics Technology

In many models of Intel processors that include Intel® Graphics Technology, you can offload a reasonable amount of parallelizable work. The Intel® C++ Compiler facilitates offloading existing scalar or parallel C/C++ code written for the CPU to the processor graphics.

OpenMP* Support

The compiler supports many OpenMP* features, including most features in the OpenMP* Version 4.0 API specification.

Compiler Options

Compiler Options provides information about options you can use to affect optimization, code generation, and more.


Intrinsics let you generate more readable code, simplify instruction scheduling, reduce debugging, access the instructions that cannot be generated using the standard constructs of the C and C++ languages, and more.


Pragmas provide the compiler with the instructions for specific tasks, such as splitting large loops into smaller ones, enabling or disabling optimization for code, or offloading computation to the target.

For more complete information about compiler optimizations, see our Optimization Notice.
