Usage Examples

Intel compilers are optimised for computer systems using processors that support Intel architectures. They are designed to minimise stalls and to produce code that executes in the fewest possible number of cycles. The Intel C++ Compiler supports three separate high-level techniques for optimising the compiled program: inter-procedural optimisation (IPO), profile-guided optimisation (PGO), and high-level optimisation (HLO). The Intel C++ compiler in the Parallel Studio XE products also supports tools, techniques and language extensions for adding and maintaining application parallelism on IA-32 and Intel 64 processors and enables compiling for Intel Xeon Phi processors and co-processors.

• Profile-guided optimisation refers to a mode of optimisation where the compiler is able to access data from a sample run of the program across a representative input set. The data would indicate which areas of the program are executed more frequently, and which areas are executed less frequently. All optimisations benefit from profile-guided feedback because they are less reliant on heuristics when making compilation decisions.
• High-level optimisations are optimisations performed on a version of the program that more closely represents the source code. This includes loop interchange, loop fusion, loop unrolling, loop distribution, data prefetch, and more.
• Inter-procedural optimisation applies typical compiler optimisations (such as constant propagation) but uses a broader scope that may include multiple procedures, multiple files, or the entire program.

Modules

Compiler Use

Prerequisites

To invoke the compiler from the command line, first, you need to load the module:

[user@login01]$ module purge
[user@login01]$ module add intel/compiler/64/2016

Using the Command Line

To invoke the compiler from the command line, use a command similar to the following:

use a command similar to the following:

• For C source files: icc my_source_file.c
• For C++ source files: icpc my_source_file.cpp
• For Fortran source file : ifort my_source.f17

Following successful compilation, the compiler creates an executable file (usually a.out if not specified in the command line) in the current directory.
